Import via file to extend record in SRM MDM

Hi There,

We are on SRM 7.0 with  SRM-MDM. 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. But because we use an idoc type for the import of products I was wondering how to extend an existing catalog item in MDM with a hyperlink.

Does anyone have an idea?

Thanks in advance.
