While creating the Change Request I am getting ABAP Dumps as below:

Category                        ABAP Programming Error

Runtime Errors               RAISE_EXCEPTION

ABAP Program               CL_USMD_MDF_DB_ADAPTER========CP

Application Component  CA-MDG-AF

Error analysis

    A RAISE statement in the program "CL_USMD_MDF_DB_ADAPTER========CP" raised the

     exception

    condition "INVALID_FIELDNAME".

    Since the exception was not intercepted by a superior

    program, processing was terminated.

and while opening the portal i am receiving the error message

500 SAP Internal Server Error

ERROR: Exception condition

"INVALID_FIELDNAME" raised. (termination: RABAX_STATE).

While checking with ABAPer we found in Method 'REPLACE_FLDNM_P' of CLASS 'CL_USMD_MDF_DB_ADAPTER'  we are getting error while checking the existence of fieldname, fieldname ACCCCDET is not available which is resulting into this dump.

Moreever this issue is come for only one user, for others its working fine.

Please help me to resolve this issue.
