Batch - MCHA-VFDAT & MCH1-VFDAT

Dear Team,

I am checking the value for the field VFDAT (SLED / BBD Date) for my material M1, Plant 2020, Batch B1 in tables MCHA & MCH1. The VFDAT is updated in table MCH1. But for the same material (M1)& batch(B1) & plant (2020), the VFDAT is NOT updated in MCHA.

Q1: Any reason for NOT updating the VFDAT in MCHA?

Note: In OMCE, I have set the batch level as "Batch unique at material level".

Q2: Is the OMCE settings have any impact on VFDAT update in these tables (MCH1 & MCHA)?

Thanks
