Using the PO_CHANGE_API1_S.update_po, the following columns can be updated in a Purchase Order.

– Promised_date
– Need_by_date
– Quantity
– Unit_price

Importance of LAUNCH_APPROVALS_FLAG
=================================

– Indicates if you want to launch APPROVAL workflow after the update. Its value could be either ‘Y’ or ‘N’. If not provided, the default value is ‘N’.
– If we are passing launch_approvals_flag =>’N’, the PO is remaining in the Requires Reapproval status.

Post Update PO Validation:
====================
1. Set the PO status to REQUIRES REAPPROVAL.
2. Increment revision number if the PO was in APPROVED status before the update.
3. Launch the PO Approval workflow if LAUNCH_APPROVALS_FLAG = ‘Y’.
4. If the quantity was adjusted down to be equal to the total quantity received or billed, then set the appropriate closed code and roll up the closed code to line and header levels.
