BAPI for Conventional Invoice Verification MR01 - SAP R/3 4.5B

Hello,

I am working on a custom interface that posts a Conventional Invoice Verification

to transaction code MR01.

I am looking for released function modules or BAPI's that will perform this function.

The aim is to avoid BDC due to a greater potential for upgrade issues.

I am working on version 4.5B and have had difficulty trying to find a solution.

I have tried :

1) BAPI_ACC_DOCUMENT_POST - this posts a FI document via FB01.

2) BAPI_ACC_INVOICE_RECEIPT_POST - this posts a FI document via FB01.

Neither of the options above post an Invoice Receipt

that hits MM.

3) IDOC Process Code - the process code behind IDOC processing calls a function module that

uses call transaction and hence BDC processing.

4) OSS searchs, web search, colleagues

I know that SAP moves to Logistics Invoice Verification in later versions and that BAPI

Incoming Invoice and Method CreateFromData is suitable for my requirements.

My question is for version 4.5B are there released function modules or BAPI's that will post

to MR01 without using a screen based approach.

Kind regards,

Mark
