I’ve developed several different Mobile App Builder Functions to scan barcodes. I’ve successfully developed a function to consume inventory from the alm_consumable table. Using a single input of type Barcode and that is working.
Example Code in WriteBackFunction:
(function WriteBackAction(parm_input, parm_variable, actionResult) {
// get input values
gs.info('Consume Inventory Function: parm_input = ' + JSON.stringify(parm_input, null, '\t'));
})(parm_input, parm_variable, actionResult);
This is the output of the function in the system logs:
Consume Inventory Function: parm_input = {
"stockroom": "32c1ffd51bf17110a95611f8bc4bcb72",
"quantity": "1",
"site_location": "dc8f4ef4db6f8c50f76bda75ca961970",
"barcode": "CPM0003194"
}
The first method that I tried:
Configuring my Consume Multiple Barcodes function I used this reference: Configure input form screens with grouped scan barcode inputs (servicenow.com)
My configuration:
Input form section:
Result
- that the barcode scanning works and will scan multiples barcodes:
- It appears to carry values back to main form:
- However, the submit doesn’t send all the input values.
Using this same code in my Consume Multiple Function:
(function WriteBackAction(parm_input, parm_variable, actionResult) {
// get input values
gs.info('Consume Multiple Function: parm_input = ' + JSON.stringify(parm_input, null, '\t'));
})(parm_input, parm_variable, actionResult);
I get this which is missing barcodes:
Consume Multiple Function: parm_input = {
"quantity": "1",
"stockroom": "3beabf471bbbf110a95611f8bc4bcb70"
}
Based on the documentation I’d expect it to look like this:
Consume Multiple Function: parm_input = {
"barcodes": {"inland_barcode": ["CPM0003647", "CPM0003647"]},
"quantity": "1",
"stockroom": "3beabf471bbbf110a95611f8bc4bcb70"
}
Then second I tried this method:
Configure a grouped input for multiple scans (servicenow.com)
But the barcode inputs did not show on the Input Form Screen. But the input shows up after I click submit. The functionality appears to work , and it has the same output to the log files.
