Problem with 2LIS_11_VAITM extractor

Hi

I done :

1. Extend the 2LIS_11_VAITM extractor (structure and user-exit) adding new fields for user specific partner roles

2. Added code in RMCSUZ10 as described

But when I change ONLY partner in sales order (z- role) there is no record in LBWQ. But when I change standard partn role (ex. RE) system generate record in queue.

What should I do more?

Thanks!
