Billing to Project Costing interface - After Initial Bill for Prepaid Contracts

Hi,

After generating initial bill for prepaid contracts (Payment) and running BIPCC000 only one side of the entry is being populated in PROJ_RES_TMP_BI table and that's the deferred revenue row (entry created in BI_ACCT_ENTRY table debit Billed AR and credit Deferred Revenue. After running Retrieve Billing Items, this row (deferred revenue side of the entry) doesn't clear from PROJ_RES_TMP_BI table and doesn't get interfaced to PROJ_RESOURCE either. Other transactions flow to PROJ_RESOURCE normally.

1. What entry should the initial bill for prepaid contracts should be populated in PROJ_RES_TMP_BI? Should both, debit & credit go in there or just the deferred rev row as it's happening for us?
