How I can notify hours of equipment in CAT´S

Hi Fellows,

I need to know how I can notify hours of equipment in CAT´S, actually I know how to notify hours of woerkforce in CATS trough transaction CAT2, but I can´t change the criteria of entry in this transaction.

In CAT2 the system require personal number to refer an a employe but... How I can entry any activity class or another criteria as work centre

Thanks in advance
