Rule 5: Changing the planned starting time in the properties dialog
● If the planned starting time in the properties dialog is set greater than the end time of its
predecessor batch, the position and thus the real start in the Gantt chart shifts to the right.
● If the planned starting time in the properties dialog is set smaller than the end time of its
predecessor batch, the position and thus the real start in the Gantt chart shifts to the end
of its predecessor batch.
Rule 6:
● In the case of a manual start of a chained batch, the start is always carried out immediately,
irrespective of the start mode, position in the Gantt chart, completed predecessor batch,
planned starting time or GAP time.
Note
Please note that the rules described here refer principally to end chaining. However, they
also apply analogously for start chainings in the case of correct interpretation.
Procedure in BatchCC:
1. Select the menu command Planning > Set batch order.
Result: The "Set batch order" dialog box opens. All batches and their start and end times
are displayed on the left.
2. Select the correct time range on the right.
3. Select a planned batch in the time window that you want to chain with another batch.
4. Select the "Chain with predecessor" or "Chain with successor" command in the shortcut
menu.
5. Then select the predecessor or the successor batch.
Chaining mode
● You can also specify the following modes for the batch via "Properties" (shortcut menu) in
the "Chaining" tab:
● Start chain: This batch starts running as soon as the predecessor batch starts.
● End chain: This batch starts running only after the predecessor batch is completed. If the
batch is aborted or stopped, a query is displayed asking whether the next batch should be
started.
