Dear Rohan
the generation of the phrases is related to existing identifiers (on several objects); the DG filling need "assigned" regulatory lists to the identifiers to do the job "correct". May be the identifiers are not set up correctly and therefore the system is generating to many phrases (this is only a guess). On the top may be the "usage" of the identifiers need to be checked.
Can you please check deeper? Does it happen only in context of "one" material - REAL_SUB relation ?
