FABH0237E GU WITH SSA NOT POSSIBLE BECAUSE ROOT HAS NO KEY-FIELD

Explanation
 The last printed GU control statement contains
a relational operator in columns 16–17. This means that program FABHTEST
should issue GU calls with an SSA qualified on the key field of the
root segment. However, the root segment has no key fields.

System action
 FABHTEST ends abnormally.

User response
 Remove the GU control statement.
