Budget Checking for receipt accruals have bypassed lines

Hi,

We are on PeopleSoft 9.2. I am trying to understand the receipt accrual process. During our AP Close, we ran the receipt accrual and then the budget checking for receipt accruals. When I queried the KK tables( header and line), I see some discrepancies in KK_SOURCE_HDR & KK_SOURCE_LN.

Purchasing >> Receipts >> Budget Check-- For transaction types -PO_RAENC & PO_RAEXP.  After running the budget checking, we Query tables KK_SOURCE_HDR & KK_SOURCE_LN. Rows are inserted into header but not all are inserted in line. Rows are inserted into this KK source line table only when they pass budget checking and impact the budget ledger. We see that that for rows where the budget line status is B or bypassed in RECV_LN_ACCTG table, the KK_SOURCE_LN table is not populated. The Transaction type is DST and ENR corresponding to the budget line status for these rows in RECV_LN_ACCTG table. What does budget line status of B or Bypassed in RECV_LN_ACCTG table denote ? Is there any setting on the corresponding PO/receiver which is causing these lines to be bypassed ?
