Invoice Generation
You can generate invoice records either automatically or manually. To generate invoice records automatically, you run the Invoice Generation program (R52121). For advanced contract billing contracts, the system performs these additional tasks when you run the R52121 program:
Summarizes records for funding level contracts that are associated with the same invoice level contract into one invoice.
Compares the period of performance (POP) dates for the funding level contracts with the values in the Bill From Date and Bill Through Date processing options for the R52121 program to determine which transactions to include for processing.
Updates these date fields in the Invoice Summary Workfile table (F4822):
Invoice Print From (Inv Lvl) (invoice print from invoice level)
Invoice Print Thru (Inv Lvl) (invoice print through invoice level)
Invoice Print From (Fnd Lvl) (invoice print from funding level)
Invoice Print Thru (Fnd Lvl) (invoice print through funding level)
Processes cost, fee, and award fee billing lines and, if the amounts for these billing lines are greater than the limits, creates excess billing lines and records in the Billing Detail Workfile table (F4812).
Writes the batch number to both the invoice and funding level contracts.
To generate invoices manually, you use the Create Manual Invoice program (P52121). When you enter a funding level contract number, the system enables an additional tab on which you can enter up to nine additional funding levels. You can also enter an invoice level contract number and the system processes invoices for all funding levels attached to that invoice level. When you generate invoices manually, the system performs the same actions as when you run the R52121 program.
