Limit Number of Digits in Quantity Field

Limit Number of Digits in Quantity Field

Some clients would like to limit the quantities entered in Panatrack transactions, especially those entered via barcode scanning. Using the RegEx capabilities of PanatrackerGP, clients can prevent users from scanning an all-digit barcode like a UPC into the quantity field.

Configuration Steps

  1. Navigate to Configure menu on the left and select System Settings.
  2. Select the Barcode Control menu.
  3. Set Enable Regex Features to True.
  4. Scroll down to and tap Data Pattern Quantity Field.
  5. Clear out the existing ^.*$.
  6. Replace with: ^[0-9]{1,3}$

Notes

The setting ^[0-9]{1,3}$ will limit the entry to 3 digits. A quantity of 999 is the highest number that could be entered into the quantity field. Panatrack will not truncate a quantity or barcode entered, it will reject anything with more than 3 digits.

Changing the 3 in this string will impact the digits allowed:

  • ^[0-9]{1,4}$ allows 4 digits
  • ^[0-9]{1,5}$ allows 5 digits

Quantity Field setting: ^[0-9]{1,3}$ where 1,3 indicates no more than 3 digits can be entered (limit 999).
