IDSM Chargeback is getting stuck at Claims workbench -- Not progressing for approvals

Uploaded a webadi template for chargeback data

Channel Revenue - Sales data upload window --- Processing for some time

Automatically updated to  Processed  -- Pending Payment -- Pending Close

At this point i could find the Claim in Claims workbench

Settlement method is defaulted from Customer trade profile

Claim get stuck at this point

Manually user is getting into Claim window and requesting for approval --- Our claims do not require any approvals (we disabled approvals) -- so we expect workflow to pick up the data and push it to AR interface table.  What configuration options needs to be checked to get end to end automated process ?
