RM111 Error reading reporting point information

Hi,

I got a problem here.

I am learning about repetitive manufacturing.

At first we have 2 version of the material. we use prduction line at the first.

and now i want to try about reporting point so i maintain the routing for the material version 1 and 2.

In the routing for production 2 i use two opration 10 (milestone) and 20 (milestone)

I set in my rep profile that RP is mandatory and GR at the last RP.

But when i MFBF i fot error message RM111.

Did i miss something to maintain?

Kindly help

Best regards,

Freddy ha
