User Exit or Badi for planning table

Hi all,

if I move an order in the planning table (CM25) I have to consider other orders.

Example:

Order 33 has an operation 01 and an operation 02. So I have 2 orders: 3301 and 3302.

If I move order 3301 I have to check order 3302. If there is a overlapping, I have to move order 3302.

Has anyone an idea for an user exit or a badi that I can use?

Does anyone have any ideas for an user exit or a badi that I can use?

Thanks Henry
