When I preview in A/R or A/P if ther is an error (eg:duplicate invoice number) the error does not appear until I post the batch. Is there anyway that Softrak can flag this error in the preview function, so the error can be corrected before posting takes place.

I assume you would like to see similar error checking for the AR and AP batch listing reports as exists for GL.

We can add this to our suggestion list. To make this useful, there would need to be a complete list of potential errors that could be found within a batch.
