PS CN33

Hi guru,

I need just some clarification about how works CN33

This is my scenario

Time T0: I have a WBS BOM with materials that need to be procured in advance. I run Cn33 and I assign these materials to activity A

Time T1: there is a change in my WBS BOM. I have added a HALB component with its BOM. When I run CN33, the system add this HALB to activity B but deleted the raw materials that I add in istant T0

Is it correct? I understand that CN33 works only on the changes to WBS BOM ...

Please, could you help me?

Thanks

Regards

Raffaele
