BAPI for Process Open items in FPE1

Hello experts,

I was looking for the BAPI to process the open items like we do in FPE1.

So far I found FKK_CREATE_DOC_AND_CLEAR and it works.

However, this FM is not released by SAP.

Wondering if this is used by you guys and is it could be use.

Or is there any better FM or BAPI.

Thanks,

Sachin
