Diagnosis
You have used a decision operation. The following two cases arepossible:
1. Decision operation without comparison:
You have specified a value for the variable key which does not matchthe field type of the decision operation. You have, for example,specified an alphanumeric value instead of a numeric one as defined inthe Data Dictionary.
2. Decision operation with comparision:
You have specified a value for the variable key which does not matchthe field type of the decision operation. In comparisons, you may onlyspecify the characters '<', '>', '=' or '*' in the variable key. Or:both fields for the comparison (the decision operation field and thedirect value or the comparison field) must be of the same type.

Procedure
Check the values entered in the variable key against the decisionoperation fields or the values before and behind the '?' character.
