Thank you for such a detailed blog. i had few queries, can you please help me with those.

Do we need to install CIG add -on, on the S4 HANA system where MDG is installed.
How to add custom fields in the SLP -MDG integration.
I don't see this business partner documents in the mapping tool. What can be the reason for that?

Request you to please help me with the above queries as soon as possible, it would be really helpful.

Hi Bansal,

We had a co-deployed system so we installed CIG on the same system.
Custom fields can be added by enhancing the proxy structures and the values can be passed with FIELD_NAME = 'ZZXXXX' and FIELD_VALUE = 'YYYY' and it can be retrieved in BAdi and added to the CR
Am not sure about this, may need to check with SAP on this via support incident. But by standard documents are not supported as part of SOA.

Hope this helps.

Thanks,

Nalla B,

Hello Balaguruswamy,

Thanks for the post and I have below queries on SLP to MDG-S / ERP integration for Supplier request.

Case 1: If we are using MDG-S as hub type and wanted to integrate Ariba SLP to MDG-S and then to ERP. In this case CIG Addon on ERP system and above mentioned Business partner function activation in MDG-S are enough ? No CIG addon or any other table maintenance is required in MDG-S for SLP ? Basically its not clear from Guides that what to do in MDG and in EPRs. Please comment.

Case 2: If we dont want to have MDG-S in middle of SLP and ERP , can we just add CIG Addon in ERP and activation Business partners above is enough in EPR to create the SLP interfaces ?

Hello guys,

This scenario works as well with S4HANA? In the graph you mentioned SAP MDG / SAP ECC, just want to be clear. We want to install MDG as AddOn and integrate with Ariba, we found there is another scenario but is MDG as a HUB. Your input will be appreciate.

Best Regards
