I'm not a financial functional person.We had a problem few days back. Here is the problem:
1. Tax code for a sales invoice was wrongly mapped to a diff account.
2. With the help of Infor support line, we discovered this and corrected the same using the correction program.
3. while we were posting thr invoice to finance (after correction), we got an intergration error 'Cannot define ledger account(sls).
4.Again infor helped us out by creating the mapping for the respective item group on session(tdsls6102m000).
PLS NB: The company never maintained the mapping for individual item groups in this session.

The question i wanted to clarify is:
1. If there was no mapping maintained in the past for specific item groups, how were the invoices being posted correctly all this while???
2. If the default setup, was already present( which was existing), then why did the particular invoice did not get posted?
3. has it got anything to do with the correction programs (of deleting records from specific tables???)

Following is the attachment of the same.
Need help!
