Custom 261 movement type assignment to order type?

Hello Experts,

I need your help to understand how to assign custom Goois issue movement type (copy of 261) to specific order type. Current scenario is the client uses production orders for various business units using standard 261. However for specific Custom production order type, need to assign a custom goods issue movement type to that order type.

Please note, am aware standard movement type is assigned in tcdoe: OPKA under CO package (At Client Level). Obviously I cannot change that as other production orders types still need to use standard movement types.

Anybody configured this scenario, let me know

Regards,

Ram
