Diagnosis
You want to start an initial run for program &V1&. However, an initialrun is not permitted for the time period that you entered. Some possiblereasons for this are:

• The start date or end date overlaps with an existing initial run for
regulation &V2& and scenario &V3&.

• The start date or end date that you selected is not adjacent to existing
runs for this regulation and scenario.

• The last run of substance volume tracking went up to a current date,
minus the SVT_TRACKING_DIFF_TIME environment parameter. Consequently,only delta runs are allowed.

System Response
The system does not permit overlapping between start and end dates, orgaps for runs that have already been performed. Otherwise, this couldresult in inconsistent data because material documents could beprocessed twice.

Procedure
Select the start date or end date so that it is adjacent to the existinginterval &V4&. If necessary, restrict the regulation and scenario on theselection screen, since these may have different start or end dates rela
ting to previous runs.
Perform a delta run.
