When an action block is generated, the generation is not complete and the following error message is output to iefmd.log.
TLclst::build - Must have a destination operand
The "Must have a destination operand" message means that there may be a corruption in an action block statement line.
It is suggested to run Encyclopedia validation and also check if Toolset generation has same problem or not.
Check the errors in the Encyclopedia Validate Report.
Contact CA Gen Support for further assistance with repairing any corruptions.
