OBSA stands for Offset Balance Sheet Account, a field to enter the Balance Sheet Account for the offset posting code.

When debit offset or credit offset is set to Yes for an event type posting code (posting code A), it indicates the posting code is used to offset the other posting code (Posting code B). The posting code A is called offset posting code. The event type with offset posting code setting will combine debit and credit into a single posting line using the COA entered on the accounting line with the only exception of posting code and balance sheet account. The BSA field will be used for primary posting code (Posting code B) while the OBSA field will be used for offset posting code (Posting code A).

Users are ONLY allowed to manually enter OBSA for the offset posting code when:

1. “Use OBSA from Actg line for Pair X” is flagged for the event type in the Event Type (ETYP) table

2. “Offset Override Allowed” is flagged for the document code on document control page (DCTRL)

If the OBSA field is left blank on the document accounting line, the OBSA will infer the default balance sheet account defined for the offset posting code (Posting code A) on the posting code (PSCD) table. For JV type documents, because JVs are manual adjustments, BSA fields should ALWAYS be used for recording the balance sheet accounts.

Event type AP01 and document code GAX will be used to demonstration the concept here.

AP01 is the default event type for GAX. The credit offset is set to yes for posting code D001 – Disbursement payable, which means the posting code D001 is used to offset posting code D011 – External Accrual Expenditure. The AP01 event type will combine debit of D011 and credit of D001 into a single posting line using the COA entered on the GAX accounting line.

The “Use OBSA from Accounting Line for Pair A” box is flagged on the event type AP01, and the “Offset Override Allowed” is flagged for document code GAX on DCTRL table. This setup allows the users to enter the desired balance sheet account on GAX OBSA field, and post the credit balance of D001 into that desired balance sheet account. If the OBSA field on the GAX accounting line is left blank, the system will infer the default balance sheet account defined on the posting code table for D001.

The default balance sheet account defined for D001 is Disbursement Payable, and the first inference is from System Wide Special Account. Balance sheet account 2100 is defined for Disbursement Payable on special account table, so the credit balance of D001 will be posted to balance sheet account 2100.

Check the posting line of the GAX. A single posting line is created for debit and credit using the COA from the GAX accounting line. The Debit posting uses the primary posting code D011 (Accrued Expense) without a BSA and the Credit posting uses the offset posting code D001 with an OBSA 2100.

If OBSA is not left blank on the GAX accounting line, the balance sheet account entered will override the default 2100 defined on the posting code table for D001. Please see the example below.
