I attempted to run receipts in a range, that is: I asked for all type X receipts with batch # greater than 1900.  I expected to get about 75 receipts and instead I got 110.  Those extra receipts were from 5 or more years ago and they weren't even the type that I was asking for.  Ultimately, it took me far more time to clean up the mess than it would have to run the batches one by one.  I can't see any reason why I got those odd receipts.

My first guess is how the batch numbers were searched by the software.  Some programs/software settings seem to sort 210 as greater than 1900. I guess looking only at first digit.  If that's the situation, any batch # greater than 19 may have been read. :-)  Have seen this happen when I've sorted things.   Just a thought...
