How to Fix Sage 300 Posting Errors – Step By Step Guide If you’ve been using Sage 300 (formerly called “Accpac”) for some time, you’ve likely run into a Sage 300 Posting Errors message at some point. These errors can happen when trying to post to the general ledger, accounts receivable, or accounts payable. Here’s a rundown of some common Sage 300 errors and how to fix them. Step 1: Print a Posting Errors Report You might be trying to post a transaction to a locked period or entering an invoice that has already been created. The best way to check for posting errors is to print a Posting Errors Report in Sage 300. This should be your first step to find any batches that didn’t post because of an issue. You can find the Posting Errors report in the Transaction Reports section for accounts payable, accounts receivable, and general ledger. For the general ledger, it’s called the Posting Journals Report, and it’s located in the G/L Reports area. Common Posting Errors & Fixes in Accounts Payable Here are some common errors and their solutions for accounts payable: Error: Posting to a locked or inactive year Fix: Check that you’re posting to the correct year. If that’s correct, go to Common Services, then Fiscal Calendar to unlock or activate the year. Error: Invoice XXXX already exists Fix: You’ve already used that invoice number for the vendor. Check if you’re duplicate the entry. If not, you can add a letter or number at the end of the invoice to help identify it. Error: Net invoice amount is not equal to the net distributed amount for batch xxxx, entry xxx Fix: Review the entry, taxes, and totals to find the difference. Common Posting Errors & Fixes in Accounts Receivable These are some common errors and fixes for accounts receivable: Error: Total amount of details does not equal the total amount of the invoice Fix: This happens when a tax authority is set to use standard cost and an item has a unit price of $0 in an order. When the invoice is sent from O/E to A/R, the tax is calculated using the selling price instead of the base price. Check the tax authority settings and ensure item pricing is correct. Error: Cannot process document. Customer number is inactive Fix: Make sure the customer record is set to active. If the customer is already active and the error keeps showing, there might be an issue with the ARCUS table — your Sage partner should check it. Error: Document number XXXXX already exists Fix: Ensure all users are out of the affected module. Go to Options and update the next number to the next sequential value. This often happens when a manual number was used before, causing a conflict with the automatic numbering system. Common Posting Errors & Fixes in General Ledger (GL Error Batch) Here are some common errors and fixes for the general ledger: Error: Cannot post to a future year Fix: Create a new fiscal year in the Fiscal Year Calendar in Common Services. Error: Cannot post to locked fiscal period XX Fix: Unlock the fiscal period or change the journal entry to an open fiscal period. Error: Journal detail source ledger XX is not on the control account’s eligible list Fix: Review the GL account setup and add the source ledger you want to post to the control account.
