BADI For multilevel categorization

Hi ,

I am using mutilevel categorization in service request SRVR.

In the schema i add to the lower level a service item.

But when i select this level in the transaction i dont get the service item.

I put a break point it the BADI

But it seems that the program not going throw this BADI.

How can i use this functionality ?

Thanks Lior Cohen.
