Displaying unit allocation and changing it if necessary

Unit allocation and run time
A unit can only be involved in the production of one batch at any one time. The unit allocation
is displayed along with the duration of the allocation and is not related to any particular recipe.
The length of time required by units involved in a batch is set when the recipe is created. The
times are relative to the start of the batch and take into account the actual quantity of the batch.
If necessary, you can adapt the unit allocation in the properties dialog of the batch.
Note
The allocation times of the units are planning values used to optimize the use of facilities.
Please remember that these allocation times are not exactly the same as the actual times
required for batch control.
Procedure in the BatchCC:
1. In the "Orders" folder in the BatchCC select the object "Batch" below the production order.
2. Select the menu item Edit > Properties.
Result: The dialog "Properties of <batch name>" is displayed.
3. Select the "Allocation" tab.
Result: The units reserved for the recipes are displayed in the table.
4. If required, modify the unit allocation. The "Unit" list box shows only the units that also have
the recipe phases being used.

Overview of the unit allocations
