This idea is dedicated to ISV solutions, and try to repair a lake of extension of planning optimization, related with custom dimensions. We loss functionalities, compared to legacy planning.

Context : use of a custom tracking dimension (added by ISV). In the tracking dimension group, check the standard "Coverage plan by dimension" for this dimension.

Actual behavior :

Planning optimization generates new planned production order, with a custom dimension value driven by "Coverage plan by dimension". Fine.

Based on active Item BOM version, derived requirements are calculated. In those derived requirements, the custom dimension is an empty value. In the legacy planning, extension is possible, and we can initiate the value as required by business logic.

Our request : In the tracking dimension group, for custom dimensions only, add a checkbox "Planning Inheritance".

Behavior : When calculating new derived requirements, the custom dimension value is to be inherited from header to lines.

Technically speaking, inheritance flows : ReqPo => ReqTrans.

Remark : such a checkbox is relevant with custom tracking dimensions only, and irrelevant with standard tracking dimensions like serial or batches. It could remain hidden in the standard form, and be displayed only through ISV extension.
