Diagnosis
The system was instructed to use tool function &SYST-MSGV1& of thestandard delivery of the logical service for creating settlementschedules. However the tool function identified an invalid call. Atleast one of the following required parameters was not transferred:calendar, time unit of settlement schedule period, number of timeunits per settlement schedule period, settlement schedule start orsettlement schedule end.

Procedure
Check that the configuration of the object-dependent parameters of thesettlement schedule rule used is complete. The information required isthe time unit of the settlement schedule period, the numberof time units per settlement schedule period and either thenumber of settlement schedule periods or the date field for theend of the settlement schedule horizon. If both the number ofsettlement schedule periods and the date field for the end of thesettlement schedule horizon are missing, the settlement schedule horizoncannot be set. Remuneration scheduling is not defined in this case. Ifboth are specified, the date field for the end of the settlementschedule horizon has priority over the statistical entry quantifying thenumber of settlement schedule periods.
If the problem occurs although the settlement schedule rule has been cor
rectly configured, contact your system administrator for an analysis andsolution of the problem.
