Hi,
KDH2 is the place where users add new account groups and assign GL accounts to those groups.
these accounts are extracted in to BW using the data source - 0GL_ACCOUNT_ATTR
account groups are extracted using - 0ACCOUNT_0109_HIER.
see if they are active in your BW system. Normally these are scheduled to run daily to get the changes updated in BW system.
You can check in BW system --> rsa1 --> info objects--> 0account --. double click.
you can see the groups and accounts assigned to it.
check below thread.
