Production Order Planning Plant

Hi All,

We have plant A & B

We would like the production order to be created in plant A, but the Goods receipt to be done in plant B.

Entering a "Planning Plant" when creating a production order allows this.

How can I make Plant B default as the planning plant for particular materials in plant A?

We do NOT want to change the the default for all materials in plant A.

Ideally this would default when converting a planned order into a production order as MRP will be generating planned orders

Thanks
