PCLaw® Displays a Warning Message that the Invoice Box Contains a Number that Already Exists

When you attempt to create a bill with an invoice number that already exists, PCLaw® displays a warning that The Invoice box contains a number that already exists. Do you want to continue without changing it? The error appears because PCLaw® advances the invoice number sequence when you create a bill even when subsequently remove that bill. PCLaw® still uses the invoice number for tracking purposes.

Take either of the following actions when PCLaw® warns you that the invoice number already exists:

  • click Yes to accept the duplicate invoice number and continue with the bill
  • click No to return to the Bill Selections window and enter the next unused invoice number

If you do not know what the next invoice number is, you can run the Invoice Journal to find the last invoice number.
