Documents/billing orders are missing from secondary installation &1

What causes this issue?

Billing documents from secondary installation &V1& are required for
billing primary installation &V2&. These billing documents must cover a
minimum period of &v3& to &v4&. The only exceptions are periods in which
installation &v1& does not have contract or where there is no secondary
installation for primary installation &v2&. However, the system could
not find any billing documents that cover this period completely.

System Response

The billing procedure for primary installation &v2& is cancelled.

How to fix this error?

If secondary installation &v1& is <DS:DE.DISTREL>distribution- relevant
</>, the real meter reading documents of secondary installation &v1& are
processed and the existing billing orders are simulated. Check whether
the billing orders exist.
If the secondary installation &v1& is not distribution-relevant, only
the real billing documents are processed. Check whether all the billing
orders of secondary installation &v1& have been billed.
The billing periods of a primary and a secondary installation must
correspond with each other within certain intervals. Billing periods are
normally defined by each <DS:DE.ADAT>meter reading date</>. The periodic
meter reading in the secondary installation may not have been made
within the interval set by the periodic meter reading in primary
installation &v2&. For more information, see the
<DS:DE.LMARGIN_SUB>billing interval of the secondary installation before
the meter reading date</> and the <lS>billing interval of the secondary
installation after the meter reading date</>. Thes are defined by the
<DS:DE.INSTGRTYPE>grouping type</> of the primary installation.
