MDG-F GL Account Replication to MDG Hub

Hello Expert,

We are using MDG as Hub. I am facing issue when I am creating GL account.

Issue is Data is getting updated at ECC system but not in MDG system ( Table SKA1 and SKB1 is not getting update ).

Idoc is showing following message .

1. The data contains error, you cannot save                                   MDG ID 511 MSG  class : FH

2. Alternative account number already assigned to account 330001 MDG ID 022  MSG class : FH

Any hints to solve this issue
