Network re-assignment to WBS element

HI SAP Gurus,

As per SAP stantdard, we can create network and network activities, and we can Assign it to Project definition and WBS element.

Also, it is possible to reassign network and activities to other Project definition and WBS element.

Is there any possiblity to restrict this RE-assignment?

Any pointers will be helpful.

Thanks and regards,

Narender.
