Reference point

Hi Friends,

Hope all are doing well,

I hv one doubt.

We maintain the reference point in network activity(in assignment tab) for BOM transfer.

When I am going to enter any value suppose A there I am getting the error as

Entry A does not exist in TCNRFP --check entry.So now

I want to ask that whether reference point is maintained by PS person if yes then how can I do this and if not then what I shud do?

Help will be rewarded.

Regards
