PO creation and GR query

[Former Member]

Hi

I am relatively new to the SRM module and I have query for you guys. In extended classic scenario, (or irrespective of deployment scenarios) for PO creation in the backend R/3 system I believe the BAPI is called through RFC and hence PO is created in R/3 synchronously whereas for GR confirmation and invoice posting the ALE/Idoc is used in which case its asynchronous. What exactly is the logic behind this?

Thanks

Rashmi

P.S if anybody has any useful material or write up about these concepts please send it across to rashmiraj82@yahoo.com

Hi Rashmi,

You are correct : BAPI for PO, PR, reservation and idocs for GR and invoice.

Kind regards,

Thanks Yann. but why? why idocs for some purchasing docs and BAPI for others?
