Diagnosis
The length of the field values of decision operation fields located ina path of the hierarchy tree, with one byte of space to separate onefield from the next, is greater than 18 bytes.

Procedure
Check that the field contents actually correspond to the field length.
Example 1: You need a decision operation for the FCODE field. As ofRelease 4.0, the field has a length of 20 bytes. However, all of thecontents expected for FCODE consist of just four characters. In thiscase, enter your decision operation for FCODE with a length of 4.
Example 2: The field contents are not completely different each time.Instead, just two characters differ as of the third character. In thiscase, enter your decision operation for this field with offset 2(offset = position - 1) and a length of 2.
