Import via file to extend record in SRM MDM

Hi There,

We are on SRM 7.0 with the user interface add-on and use SRM-MDM as catalog with TREX  as an index platform.

Masterdata is automaticly uploaded from ECC to MDM datamanager via Idocs.

We have a repository with a little less then 10.000 products and we would like to add images to the products. This can be achieved by maintaining a hyperlink type rendering. But because we use an idoc type for the import of product I was wondering how to extend an existing catalog item with an hyperlink.

Does anyone have an idea?

Thanks in advance.

Jorgen
