How to map P.O retention in S4HC and proceed same with Invoice.

Dear Folks,

I came to know from SAP , posting invoice against purchase orders with retention is not supported in SAP S/4 HANA Cloud, therefore it is not possible to maintain the required document types.

Before in ECC while invoice process, teh accounting entries for (FI document) were posted with net invoice and retention amount

Do any one has knowledge how to handle retention P.O in S4HC any workaround

Thanks

Emraaan.
