Update/Replace old/exsisting RREQ in S/4 Via SAP CPI-DS

Hello Experts,

We have a requirement to replace old PREQ items with latest PREQ every time, when we send the data (Transport Receipts) from IBP to S/4. To create the PREQ in S/4 we are calling the BAPI_PR_CREATE using its RFC function module via CPI-DS and it is successfully creating PREQ is S/4. But the challenge is every time is it creating new PREQ no even if we are sending same Material, Location Combination from IBP with updated QTY. Is it possible to somehow Update/Replace the old PREQ automatically in S/4 while sending new ones from IBP via CPI-DS?

Thanks,

Ratan
