IDoc from MDGF misses some fields that are present in CR

Hello Experts,

In MDGF the data replication is set up as ALE/IDoc, and after approval the replication IDoc is getting triggered.

In DRFRSD and WE09, I am able to see the IDocs , both outbound with status 03 and inbound IDoc to ECC with error status .The error shows the fields are missing (Like account group, group account etc) which is already given in CR. At the time the IDoc is getting triggered it misses some mandatory fields, and replication  is not working from MDG to ECC.

Anyone faced similar issues before ?

My system is MDG 6.1.

Thanks
