Glen, I am passing this information on from our Accounting people. I hope it is helpful.
We have used 3 methods of ensuring our GL balances are the correct balances and determining what we owe a supplier.
1. Just using the transaction columns of the msbK,L & M to compare to the monthly transactions recorded in the GL
The transaction columns on the report are correct so keeping a running total on a spreadsheet monitors the balances
The trick is to run these reports for an accountng period, rather than leaving the accounting period blank, and to do this after the accounting period has been closed for all modules.
2. Using the aged listing msr26T to determine the amount owing to a given vendor/supplier.
More tricks:
1. This cannot be run for an accounting period, but if it is run after the msb267 and msb900 have been run it will show the correct balances.
2. This includes ALL invoices in the system, some of which are not recorded in the GL, or are in the GL at purchase order values
i.e those with payment status 16, 17 & 19 are included in the invoice pending account at purchase order values
those with payment status 18 are not included in any GL account
3. I have developed a MIMSVue report which will show the balance by vendor/suppier at a given point in time. If this is run after msb267 & msb900, and if no transactions have been processed afterwards, it will balance to the GL accounts. (still needs some work)
