CRM 2007 - F4 Address Search Appearing by default

Hi Gurus

On BP Create in the ICWC F4 Search Boxes are appearing for the following fields:

• Street Address

• City

• Postal Code

• Region

• Country

Region and Country are fine as they are populated as SAP Standard.

The other 3 fields should not have F4 Search Boxes visible as they do not have any data behind them. My understanding was that these fields would be searchable if Regional Structure configuration was in place, but we do not use this.

Is it possible to remove these F4 Search Boxes through configuration as they are not valid for our client.

Many Thanks

Panduranga
