PL/SQL Stored Procedures :
If you want to make a PL/SQL procedure as a Concurrent Program, then we will define that procedure by using fallowing syntax

(errbuf OUT VARCHAR2,
recoded IN VARCHAR2
PL/SQL statements;
Fnd_file.put_line (fnd_file.output, ’message’variables);
Fnd_file.put.line (fnd_file.log, ’message’variables);

ERRBUF: Used to get the error messages in to the log file if any errors occur in side of procedure.
RETCODE: Used to get the status of Concurrent Program

The Status can be either 0 – for success
1 – for warning
2 – for error

Inside of procedure body we can use all valid PL/SQL statements except DBMS_OTUPUT.PUT_LINE Instead of this we will use fallowing to API’S (Application Programming Interface).
API is nothing but a package.
Fnd_file.put_line(fnd_file.output,’message’variables); – is write for the output file.
Fnd_file.put.line(fnd_file.log,’message’variables); – is used for log file.

Steps for Developing the Procedure:
1. Develop the procedure as per client requirement.
2. Create an executable with execution method as PL/SQL stored procedure
3. Define the Concurrent Program at as
4. Attach the Concurrent Program to the request group.
5. Attach the request group to the responsibility.
6. Attach the responsibility to user.
7. User will submit program from SRW window

Example for ErrorCode and retCode:

                  RETCODE OUT VARCHAR2,
                  ARGUMENT1 IN VARCHAR2,
                  ARGUMENT2 IN VARCHAR2) IS

    L_Retcode Number;

    L_Retcode := Load_Cust_Items_Iface(argument1,

    if L_Retcode = 0 then
        RETCODE := ‘Success’;
    elsif L_Retcode = 1 then
        RETCODE := ‘Warning’;
    elsif L_Retcode = 2 then
        RETCODE := ‘Error’;
    end if;

END Load_Cust_Item;

What is SQL*Loader?
SQL*loader is one of the Oracle tool which will be used to transfer the data from Flat-File to oracle Database table.

Which files in SQL*loader?
1. Flat or Data File
2. Control File
3. Bad File
4. Discard File
5. Log File

What is Flat Or Data File: This file contains the records in a special format; these records will be fetching for other legacy. The extension of these files might be .dat, .txt, or .csv (comma separated view).

What is Control File: This is SQL loader execution file, which will be used to transfer the date from file to table. In side of these control file, we will mention the Data file path, table name, column mapping. The extension of control file is .ctl

Control File Creation:

Load data
INFILE ‘Data File Path’
INSERT INTO ‘Table Name’
WHERE deptno = 10
(column1 , empno
column2, ename
column3, deptno)

Once we develop the control file we will execute this by using fallowing command
C:> sqlldr user/passward @ Database Control = name of control file (with extension .ctl)
This command will start the control file execution, and it will try to read the data and inserting into table. After completion of this execution, automatically three files will gets created
Bad file
Discard file
Log file

Bad File: Bad file contain the records, which are rejected by the SQL*loader. SQL*loader will reject the records, when ever the Flat file format is not correct or if any internal error occurs it will rejected. The extension of bad file is .bad

Discard File: Discard file contains the records which are rejected by the control file, control file reject the records, if record is not satisfying the conditions, which we have mentioned inside of control files the extension of discard file is .dis

Logfile: It contains the complete info of the process, like no of records successfully loaded in to the table
No of records successfully loaded in to the bad file & discard file.
And where the bad, discard file gets created and time taken to complete the process.
Taking the complete log.
SQL* Loader Modes:
We can replaced the data in to the table by using any one of the allowing method

INSERT: When we are using this statement, table should be empty. SQL * loader will insert the new data form the file.

APPEND: This mode will be use to attach the new record to the existing records.

REPLACE: This will replace the existing records with new records.
C:> sqlldr userid/passward@Database control=text1.ctl path=direct

SQL* Loader Paths: We can execution SQL* loader in two paths or nodes

By default SQL*loader will be running in conventional mode, if we want to run in direct mode will use the fallowing syntax
C:> sqlldr userid/passward@Database control=text1.ctl path=direct
Direct mode will disable the table and column constrains and it will insert the data.
Conventional path will check every constrains, if it is satisfied it will insert the record
Conventional path is just like ‘insert statement’
SQL Commands Limitations:
to_date, to_char, upper, lower, Initcap, string, decode, nvl
when clause
sequence_name.next_value, Ref-Cursor
sysdate, ltrim, rtrim, constant

Functional Training  of Purchase Order Flow
What is flow of PO:

Step 1:We will be raising the Requisitions for the items which are needed.
Requisition is 2 types • Internal Requisition • Purchase
Internal Requisition is used when we are getting the items from one organization to another organization of the same business group.
Purchase Requisition is raised when we are getting the items from outside the business group.

Step 2:Once the Requisition has been approved, we will be sending (Request For Quotes) RFQ’s to different Suppliers. It contains the information regarding the type of RFQ, terms and conditions, shipments, currency.
RFQ is of 3 types
• Bid RFQ • Catalog • Standard
BID: Used for a fixed specific quantity, Location and date. This will be used for large or expensive price of equipments. That you have never order before. There won’t be price any breaks for a BID Quotation.
CATALOG: This will be used for high volume items for which your supplier sends information regularly. The CATALOG RFQ includes price breaks at different quantity levels.
STANDARD: It is used for items we need only once or not very often for a specific fixed quantity, location and date. It includes price breaks at different quantity levels.

Step 3:We will be receiving the quotations from different suppliers. Quotation is of 3 Types.
• Bid
• Catalog
• Standard

Step 4:Based on the quotations, we will be deciding the supplier and purchasing order is given to that supplier.
Purchasing is of 4 types
• Standard
• Planned
• Blanket
• Contract

Step 5:Once we receive the items from the Supplier we will issue the receipts to the Supplier. This is done in 3 ways.
• Two-Way: In 2-way we will compare PO and Invoice.• Three-Way: In 3-way we will compare the PO, Receipt and Invoice.• Four-Way: In 4-way we will compare PO, Receipt, Inspection and Invoice.

2-Way Matching verifies that Purchase order and invoice information match within your tolerances as follows:Quantity Billed <-Quantity Ordered Invoice Price <- Purchase Order Price (<- Sign is used because of tolerances)

3-Way Matching verifies that the receipt and invoice information match with the quantity tolerances defined:Quantity billed Quantity received

4-Way Matching verifies that acceptance documents and invoice information match within the quantity tolerances defined:Quantity billed <- Quantity accepted. (Acceptance is done at the time of Inspecting goods).Whether a PO shipment has 2-way, 3-way or 4-way matching can be setup in the Shipment Details zone of the Enter PO form (character).

Yes Yes 4-Way
Yes No 3-Way
No No 2-Way
In ‘More’ alternative region of Shipments block, you define the Invoice Matching option, where you can choose 2-way, 3-way or 4-way match.

Step 6:Because of these Transactions Inventory and Payables get affected.

Training  of Account Payables -> Account Payables Flow:
PO -> Receipt -> AP -> GL

Invoice ->; Payments->; Move Transactions from AP to GLIn AP there are 2 Thumb rules.

• Without supplier there is no invoice.
• Without invoice there is no payment.

How many types of Invoices and What are Invoice Types:
1. Standard: We will make all the payments based on the standard invoice. It will have the information of Invoice Number, Invoice Date, Invoice Amount, and Currency.
2. Credit Memo: We will create credit memo invoice whenever supplier is giving the discount and it will be adjusted in standard invoice. It is always negative amount.
3. Debit Memo: Sometimes Company will deduct some amount from the invoice amount. This will be adjusted in standard invoice. It is always negative amount.
4. With-Holding TAX: This type of invoice will be created to make the invoice tax to the Govt. on behalf of supplier.
5. Pre-Payment: If we want to make some payments to the supplier in advance then we create the Pre-Payment invoice.
6. PO Default: If we want to make the invoice as per the PO then we create PO default. We will give Po Number. System will pick up the complete PO information.
7. Mixed: Includes both positive and negative amount. We can match this invoice with PO’s and other invoices.
8. Expense Report: This will be applicable for the employees who are working in the Company where payables and internet expense and project account. Expense will be included.
9. Recurring invoice: We can enter invoice for periodic expense for which we may not receive. Invoice from supplier. To create a Recurring invoice first we will take template.
As per that we will create the invoice.Once the invoice is successfully completed, we can go for payments. It is of 3 types.

Manual Payment: Here we will be mentioning the Invoice Number, Bank Account, and Document Number, Payment Date and Currency.

Refund payment: This is used for Employee expenses and for adjusting the Supplier account,

Quick payment: In this payment, system will automatically generate checks. To print Checks there will be a concurrent program for each check format.Once the payment was done, we will move all the transactions to GL.

Wo is Suppliers:
Set up suppliers in the Suppliers window to record information about individuals and companies from whom you purchase goods and services. You can also enter employees whom you reimburse for expense reports. When you enter a supplier that does business from multiple locations, you store supplier information only once, and enter supplier sites for each location. You can designate supplier sites as pay sites, purchasing sites, RFQ only sites, or procurement card sites. For example, for a single supplier, you can buy from several different sites and send payments to several different sites. Most supplier information automatically defaults to all supplier sites to facilitate supplier site entry. However, you can override these defaults and have unique information for each site. The system uses information you enter for suppliers and supplier sites to enter default values when you later enter transactions for a supplier site. Most information you enter in the Suppliers window is used only to enter defaults in the Supplier Sites window. When the system enters that information in a later transaction, it only uses supplier site information as a default, even if the supplier site value is null and the supplier has a value. If you update information at the supplier level, existing supplier sites are not updated. When you enter a supplier, you can also record information for your own reference, such as names of contacts or the customer number your supplier has assigned to you.

What is Invoices:
Invoice Type (LOV): The type of invoice. Standard and Credit are the only invoice types you can enter in this window. If you do not enter a value for this field then a value will be assigned during import based on the amount of the invoice.

Standard: A trade invoice you receive from a supplier. The amount of a Standard invoice must be zero or greater.

Credit: Credit Memo. A negative amount invoice you receive from a supplier representing a credit for goods or services purchased. Note that in the Invoice Gateway you can match a credit memo to a purchase order to perform a price correction, but you cannot match a credit memo to an invoice. If you want to match to an invoice, then use the Invoice Workbench.

Debit Memo: Negative amount invoice created by you and sent to a supplier to notify the supplier of a credit you are recording. Usually send with a note explaining the debit memo. Purchase Order Matched Invoices: You can match Payables invoices to purchase orders to ensure that you pay only for the goods that you have ordered, or you can match to purchase order receipts to ensure that you pay only for goods that you have received. Purchase order matched invoices are invoices that you match to any of the following:
• Purchase order shipments
• Purchase order receipts
• Purchase order receipt lines
• Purchase order distributions

Foreign Currency Invoices: When you enter an invoice in a currency other than your functional currency, Payables uses an exchange rate to convert the invoice and invoice distributions into your functional currency for creating journal entries. You define your functional currency during setup for your set of books.
Mixed Invoices: Mixed Invoices are invoices or credit/debit memos for which you can perform both positive and negative matching to purchase orders and to other invoices. For example, you can enter an invoice for –$100 with Invoice Type Mixed. You can match to an invoice for $–200, and match to a purchase order for $100.

Prepayments:A prepayment is a type of invoice you enter to make an advance payment to a supplier or employee. For example, you need to pay a deposit on a lease, or pay an employee an advance for travel expenses. You can later apply the prepayment to one or more invoices or expense reports you receive from the supplier or employee to offset the amount paid to them. The supplier might send an invoice that references a prepayment. The supplier has reduced the invoice amount by the amount of the prepayment and associated tax. You can use the Prepayment on Invoice feature to enter the invoice.
You can enter two types of prepayments:
Temporary prepayments can be applied to invoices or expense reports you receive. For example, you use a Temporary prepayment to pay a hotel a catering deposit. When the hotel’s invoice arrives, apply the prepayment to the invoice to reduce the invoice amount you pay.
Permanent prepayments cannot be applied to invoices. For example you use a Permanent prepayment to pay a lease deposit for which you do not expect to be invoiced.

What are types of Matching? 

2–way matching: The process of verifying that purchase order and invoice information matches within accepted tolerance levels.
Payables use the following criteria to verify two–way matching:

Invoice price <= Order price
Quantity billed <= Quantity ordered

3–way matching: The process of verifying that purchase order, invoice, and receiving information matches within accepted tolerance levels. Payables use the following criteria to verify three–way matching:

Invoice price <= Purchase Order price
Quantity billed <= Quantity ordered
Quantity billed <= Quantity received

4–way matching: The process of verifying that purchase order, invoice, and receiving information matches within accepted tolerance levels. Payables use the following criteria to verify four–way matching:

Invoice price <= Order price
Quantity billed <= Quantity ordered
Quantity billed <= Quantity received
Quantity billed <= Quantity accepted

What is FOB (Free On Board): The point or location where the ownership title of goods is transferred from the seller to the buyer. This indicates that delivery of a shipment will be made on board or into a carrier by the shipper without charge, and is usually followed by a shipping point or destination (e.g. ’FOB Our warehouse in New York’). The FOB code is currently available only for reference purposes. Revenue and cost recognition is not currently determined by the value entered in this field. (Receivables Lookup)

What is Purge : An Oracle Receivables Process, where you identify a group of records for Receivables to delete from the database. Receivables purge each record and its related records. Receivables maintain summary data for each record it purges.
