Factory and planification calendar - working days

[chris_SAP]

I have forecasts stored in an information structure.

Using MC94 (or MC8G), I download these forecast in demand management.

I'd like to download it on week days (M to F).

I create planned order using MRP with MD41 and adjust them using MF50.

I want to have planned order on Monday to Sunday.

I've changed the manufactured calendar on the plant (with OX10).

Now the production scheduling is good in MF50. But the forecast scheduling is in all the week.

I try to maintain a planification calendar on my material (with lot key PK) but the result is the same.

Is there someone that have an answer to help me ?
