Function Module for REBDBU0012-BU Field Modification Criteria - Sample reqd

We are using three distinct type of Business Entities to look after three types of business of client. For this we have defined three number ranges for each such BE. Now, we wish to use Transaction code "REBDBU0012-BU Field Modification Criteria " and wish to define the field status of based in BE number range criteria.

I have discussed this in detail with my developer but he is unable to find any help/functional module. Is there any sample object available with in SAP library or if any member from SAP community could help us in it.

Regards
