Advance pricing customer key generation

Hi,

I have pricing defined based on customer gp and item #, In order to upload my data through report I need to create customer Key in F40942, Is there report which create the Key in F40942 record if i add new cat code UDC and attached it to customer and i expect this reprot should give me the record created in F40942, my customer gr in F4092 is alredy created.

for one UDC i can do it from front end..but i have build requirement hence looking for report. Report R40942 is not creating the record in F40942 do we have anyother reprot???
