The file you import from your POS system has predefined fields.
reciProfity reads those fields by knowing the position they are in in the import file.
If you received this error message
Click on the Gear/Setup/ Options. Scroll down to Sales and click on Preview Selected Filter
After selecting your POS filter click on Preview Selected Filter if you are not sure how your file should look.
In the example below you can see the expected file is a comma delimited file (like a csv file):
1. the PLU should appear in the first position (zero),
2. the number sold in the second position (1)
3. and the sales dollars in the third position (2)
This is what the import file would look like. Depending upon which POS system you use your file may look different.
Column A is the zero position Column B is the first position Column C is the second position
