ODS activation error after the structure change

Hi all,

I am getting a short dump with " "DBIF_RSQL_INVALID_RSQL" CX_SY_OPEN_SQL_DBC " error when I am trying to activate an ODS after changing its structure. Do I need to change any setting before loading the data in to the ODS after adding few more fields to it. Exact error says

"

An exception occurred. This exception is dealt with in more detail below

. The exception, which is assigned to the class 'CX_SY_OPEN_SQL_DB', was

neither

caught nor passed along using a RAISING clause, in the procedure

"ACTIVATE_SIDS" "(FORM)"

"

Thanks
