Dynamically copy same operation plant to component plant

Hi,

In transaction CO02, SAP automatically set the component plant to where the component is stored. I have a business process where the operation plant is PCH2 and the component plant is set on PSE2. I would like to change the default PSE2 to PCH2, so that the component plant would be the same as the operation one.

I could not find any customizing table to do so. I am looking forward to find a user exit of badi to make the necessary changes. I have tried using EXIT_SAPLCOMK_014 and workorder_update->before_update but the changes are not processed.

Any advise on what should be done ?

Thanks in advance for your help.
