we have activated the standard procedure to check duplicate customer master data. This is a standard procedure as below :-
Run SM30, key in Table V_T100C, select Display or Maintain, set App area F2. Here you can change current settings.
Check the transaction OBMSG for application area F2, where these messages are maintained and at this place you can convert the message from warning to error.e user needs one more field to be added to this check.
It is working perfectly fine but it only compares two fields for duplicates in the customer master i.e the customer city and name.
Is there a way to include a new field in this procedure ? For example we also want the system to check duplicate entries for field name " street 5" and give a warning /error message incase if there is another entry already existing on the master data.
