Invoice Original Amount Different From Actual Original Amount

Hello,

We have 1 invoice of $1000 that has 4 item sequence numbers.  

INVOICE_ABC

Sequence 1 is $10

Sequence 2 is $40

Sequence 3 is $50

Sequence 4 is $900

The ITEM_LINE is 0 so only one row is on the PS_ITEM table.  When the AR update is run the ORIG_ITEM_AMT on the PS_ITEM table is $10 instead of $1000.  Should the ORIG_ITEM_AMT be populated on the PS_ITEM table as the total amount for that item ($1000)?

All 4 sequence numbers appear in the ITEM_ACTIVITY table correctly.  We are on 9.1.

Thanks,

Tom
