RAR Downstream

We're 405 CD on V5R1 long gone off OSG.

We have BPCS tech support, but management not authorize call them unless emergency. Instead I get string of challenges to figure out.

Latest: A/R to be handled by another system outside of BPCS to get its info from BPCS billing process, such as A/R invoice register, then invoice input to RAR file, after cut-off date, to be deleted. Invoices prior to cut-off date to be processed old way. SIL invoice file remain intact, since it used in massive followup to support customer service inquiry, and price increase analysis.

I can write program to mass delete RAR on invoices after cut-off date. My concern is unintended consequences downstream, so that I can have alternative arrangements in place before they needed, instead of end-fiscal time discovering mountains of problems. Other than invoices awaiting customer payments, and where we apply credit debit memos, where else does BPCS use RAR file data? I don't use XRF because in 405 CD its security corrupts.

For example, do ACR230 customer ranking and SAL300 sales history get info from RCM customer master, which in turn from summarization of RAR? Where in shipping billing cycle are SSH SSD history totals populated with latest sales?

I desire to know what else will be zapped due to RAR mass deletions, because it relies on RAR content, so we can evaluate which of that we can live without, and which needs some replacement system.
