Diagnosis
An interval check (interval of the secondaryinstallation before meter reading date , intervalof the secondary installation after the meter reading date ) must beexecuted for the billing order with the key (installation
, scheduled meter reading date,billing transaction) &V1&. This is because theinstallation is a secondary installation of primary installation &V2&.
However, the system cannot determine the end of the billing period inthe comparative billing order (with the allocationdate &V3&) of the primary installation. This is because meterreadings are missing.

Procedure
Enter all meter readings for the billing order from primary installationV2 and start the procedure again.
