Unable to find Accounts Payable Accrual Account for Inventory Item

Hello,

As part of PO migration, we are having the wrong values in the accrual account for segment 8.
Expected value: 3916.322900.0000.000.000000.000.0000.00000000.0000.0000
Migrated value: 3916.322900.0000.000.000000.000.0000.NB000001.0000.0000

I am checking the accrual account setup in Procurement.
In CKH_AT_TAD i can see that for accrual account - segment 8 there is no specific segment rule

When I check the account combination rule - CKH AT Accrual Account Rule i can see that for both inventory & expense PO line, there is same setup:

source = Accounts Payable Accrual Account for Inventory Item

Could you please let us know where are we configuring this Accounts Payable Accrual Account for Inventory Item?
