SRM Field Control for Master Data fields e.g. hide Street prefix

Hi Experts,

we are using SRM 7 Ehp1.

For the RFx process we need to create bidders.

To simplify the creation of the bidder for the users we would like to hide

all unnecessary fields e.g. Street prefix / Street suffix.

I tried to use the customizing img "SAP Supplier Relationship Management --> SRM Server --> Cross-Application Basic Settings --> Extensions and Field Control (Personalization) --> Configure Field Control"

I've tried the function "Configure Control for Fields on Header Level".

There is a business object type BBP001 for bidders but only 4 fields are available for field control.

It seems this customizing entry is only for transaction data, e.g. SC, PO but not for master data.

Is it possible to hide fields for bidders within SRM?

Thanks in advance for your help!

Kind Regards

Stefan
