Dump after Account Group Changed to Consumer

Hi,

We have changed the existing account group ZXXX as Consumer for the sake of mapping name fields from CRM to ECC. Now when i try to edit the old customers in XD02/ display in XD03( with this account group ZXXX) runtime error is encountered as below:

Category - ABAP Programming Error

Runtime Errors - DYNPRO_NOT_FOUND

ABAP Program - SAPLSZA7

Please guide on how to enable the editing of these old customers.

Rgds,

Shridhar
