Problem Statement:

When grouping is performed by master planning on an item to create planned production orders, it considers the coverage group associated with that item, but not the calendar associated with the coverage group for all purposes expected. It is being considered for scheduling purposes without issue, meaning requirement dates are not being created on non-working days that may be closed on the calendar. However, it seems to ignore the configuration of the associated calendar with regard to the grouping logic used for planned order creation.

Example:
Coverage group configured to use a Period with value 5 days. Item (A) assigned to coverage group “5day”.


Calendar “Base” has 10/30 and 10/31 closed. (non-working days)

Demand:
Item A Qty 1 req date 10/26
Item A Qty 1 req date 10/27
Item A Qty 1 req date 10/28
Item A Qty 1 req date 10/29
Item A Qty 1 req date 11/01

Planned order will be created for qty 4 with a req date of 10/26.
Another planned order will be created for qty 1 with a req date of 11/01.

Ideally, the system would group all (5) days of requirements and create a planned order for qty (5) in the example above, with a due date of 10/26.
