RE: How to make an entry to Sub Ledger in AR without hitting GL
It would be important to find out how far this posting went. It would be helpful if you used David Musgrave's SQL search tool to find which tables, if any, contain this document. You could also try rebuilding the RM Key Master table by doing this:
1) Perform a backup
2) DELETE RM00401
3) Run check links on sales open and historical logical tables
Now using sales inquiry see if the document was recovered. If not, turn off AR posting through the GL. Enter your transactions. If you receive a message about duplicate document number use the results of the SQL search to remove the duplicate records. Turn on posting through GL when completed. It would be best to do this while no one is in GP.
