Oracle Error Message
ORA-36178: (XSAGGR01) To be used with AGGREGATE, AGGMAP workspace object must be declared with the AGGMAP command.
Reason for the Error
The user used the ALLOCMAP command to define the AGGMAP, so the AGGMAP can only be used with the ALLOCATE command, or the AGGMAP has no contents attached to it.
Solution
Use the AGGMAP command to define the AGGMAP.
