Map CRM contact attributes with SAP ECC additional data for contacts

Hi All,

I want to map the additional data(i.e attributes 1 -10 ) in ECC additional data tab for contact person with attributes in CRM for contact person.

I am able to achieve this in case of a prospect where the attributes in CRM classification maps to additional data in ECC.

Where as in contact person there was no CRM classification segment, but I added it manually in field groupings. Now I want to know how I can map this with the additional data for contacts in ECC.

Rgds,

Arun
