Interchangeable parts Set Up

Hi Guys,

I've read numerous forums regarding setting up MPN's, interchangeable parts etc.

For some reason T-Code PIC01 is not in my menu.

Likewise the following menu path is not present;

Logistics>Materials Management>Purchasing>Master Data>Interchangeability of Parts>

Are there any enhancements required for this functionality??

I cannot find information anywhere.

On the 720 Release, Patch Level 10
