Transaction MMPURPAMEPO is unknown while opening the ERP PO


Hello SRM Gurus,

We are in the classic scenario of SRM 7.02 with ECC 6 EHP 6 and Netviewer Business Client. (Not portal)

The problem I have is, that I get errors while opening any of the ERP documents from the query of the operative purchaser.

The query it self is working fine and I get the list of all ERP documents according the filter settings maintained.

But while opening for instance and specific PO from the list I get Transaction MMPURPAMEPO is unknown error.

It seams that the MM transaction is launched in SRM in this case.

Steps I have done:

1. Assigned the standard harmonized role /SAPSRM/OP_PURCHASER_ERPSRM for which I have generated a profile 1st. to my user

2. Maintained the system aliases in the system landscape

3. Activated the business function SRM_CONT_IMPR1

3. Activated the customizing switch SRM_701_LINK_TO_ERP

4. Maintained the attribute system alias for both the SRM and ERP in PPOMA_BBP

5. I have SAP_ALL and SAP_NEW in both the systems.

Some thoughts here please?

Thanks in Advance,
