Check for duplicates as you enter batch transactions

Summary

How to set your software to check for duplicate entries as you enter new transactions in Sage 50 Accounts.

Description

In the Customer, Supplier and Subcontractor batch entry windows, the software runs checks for potential duplicate transactions. If there's a possibility that your transaction is a duplicate, a warning appears.

To flag a duplicates, transactions must have the same:

  • Accounts reference
  • Date
  • Reference
  • Net amount

The software checks both the new transactions you're entering and previously entered transactions. You'll see a warning symbol in the column to the left of the 'A/C*' column.

If you have a lots of transactions, the duplicate check can cause a slight delay when entering batch transactions. You can check if it's activated and switch the feature off if required.
