Operator (>=) is missing for LOBM_VFDAT

Hello,

I have configured batch determination for a material which is configurable. Batches are determination incorrectly in delivery due to missing operator ">=" during delivery creation.

LOBM_VFDAT is determining as 05/20/2018 instead of >=05/20/2018 based on LOBM_RLZ. Apparently VFDAT was determined precisely couple of days back then I added LOBM_RLZ_PROZ then I got some dump. So I ran BMSM t.code in system. Then operator is missing for VFDAT in every transaction. I couldn't find the root cause for missing operator. Can you please advise your inputs to resolve this issue

Regards,

Govind. A
