SRM staging table not populating with complete value

Hi Experts,

I am doing My Shopping Cart fiori app , i am getting an error in the app "Vendor is mandatory for the shopping cart".

I have analyse and found that this error is coming because at the time of catalogue extraction , vendor and material group is not extracting from MDM.

When i manually entered these two in the staging table , i am able to create the shopping cart using the fiori app.

I am not sure why this is happening , why mdm catalog data is not getting extract properly.

Staging Table : /SRMNXP/CAT_ITM

Transaction of MDM extraction : /SRMNXP/CAT01

Any suggestion for this issue? any body faced it before?

Thanks,

JP
