Scan QR Code to Populate Multiple Repeating Fields

(0) ShareShare
ReportReport
Posted on by Zachera 22

Hi, 

 

I am building a warehousing app where I would like to give users the option to Scan one QR containing 50 products, split into multiple fields. 

 

The fields are: Product Description, Pallet Number and Pallet Quantity. 

 

Currently I do a split scan on a QR code for one product, which separates the three fields above by ";" (e.g., Description;Pallet Number;QTY). My datasource is a SP List, however open to suggestions if something else is better. 

The syntax I use currently use on the scanner button is: 

ClearCollect(SplitScan,Split(BarcodeScanner6_3.Value, ";"));Form1_5.Updates;SubmitForm(Form1_5);

And on each data card I'm using: 

Last(FirstN(SplitScan,1)).Result (and so fourth)


I would like to build in a bulk scan option, where a user can scan one QR code and that populates the SP List with say, 50 products. 

 

In this scenario, suppose my QR Code is:

Description,123456-1,500;Description,123456-2,500;Description,123456-3,500;Description,123456-4,500;Description,123456-5,500;Description,123456-6,500;Description,123456-7,500;Description,123456-8,500;Description,123456-9,500;Description,123456-10,500;Description,123457-2,300;Description,123457-3,300;Description,123458-50,475;Description,123458-51,475;Description,123458-52,475;Description,123458-53,475;Description,123458-53,475;Description,123458-54,475;Description,123458-55,475;

 

How could I do one scan on the code above, but submit as multiple entries in the SP list? I am bamboozled. 

 

Thanks 🙂

    Hi @Zachera ,

    Yes, a brain-toaster indeed . . . this will get you a collection with your values - so confirm that first

    With(
 {
 wRecord: 
 Split(
 YourScannedCode,
 ";"
 )
 },
 With(
 {
 wFields: 
 ForAll(
 wRecord As aRecord,
 With(
 {
 wSplit: 
 Split(
 aRecord.Result,
 ","
 ).Result
 },
 {
 'Product Description': First(wSplit).Result,
 'Pallet Number': Index(wSplit, 2).Result,
 'Pallet Quantity': Last(wSplit).Result
 }
 )
 )
 },
 ClearCollect(
 colYourCol,
 wFields
 )
 )
)

    Your Patch (as new records) would be something like this (I have assumed the same field names in your List)

    With(
 {
 wRecord: 
 Split(
 YourScannedCode,
 ";"
 )
 },
 With(
 {
 wFields: 
 ForAll(
 wRecord As aRecord,
 With(
 {
 wSplit: 
 Split(
 aRecord.Result,
 ","
 ).Result
 },
 {
 'Product Description': First(wSplit).Result,
 'Pallet Number': Index(wSplit, 2).Result,
 'Pallet Quantity': Last(wSplit).Result
 }
 )
 )
 },
 ForAll(
 wFields As aPatch,
 Patch(
 SPListName,
 {
 'Product Description': aPatch.'Product Description',
 'Pallet Number': aPatch.'Pallet Number',
 'Pallet Quantity': Value(aPatch.'Pallet Quantity')
 }
 )		
 )
 )
)

    Hi @WarrenBelz , thank you for your help on this one.
    Great news,the first code you listed worked, where everything saves in a local collection on my device.
    However I can't get the patch to work without a bunch of errors however. It may be simply my lack of understanding around the With/For All/Patch functionality. 

    Please assist. 

     

    Thank you

    @Zachera ,

    I have modified it in my post. This works on a test list here with the same field names.

    @WarrenBelz 

    I must be doing something incorrectly. My syntax below is still coming up with 11 errors (Unexpected characters, function 'ForAll' having invalid arguments etc.). I have written this as shown in my SP List (have tried changing the column names as per what they show up as on the backend of sharepoint when you hover over the hyperlink too and the errors don't disappear). 

     

    With(
 {
 wRecord: 
 Split(
 BarcodeScanner6_3,
 ";"
 )
 },
 With(
 {
 wFields: 
 ForAll(
 wRecord As aRecord,
 With(
 {
 wSplit: 
 Split(
 aRecord.Result,
 ","
 ).Result
 },
 {
 'Product': First(wSplit).Result,
 'Pallet ID': Index(wSplit, 2).Result,
 'Quantity Scanned': Last(wSplit).Result
 }
 )
 )
 },
 ForAll(
 wFields As aPatch,
 Patch(
 'Barcode Database Test'
 {
 'Product': aPatch. 'Product',
 'Pallet ID': aPatch. 'Pallet ID',
 'Quantity Scanned': Value(aPatch. 'Quantity Scanned')
 }
 )		
 )
 )
)

    @Zachera ,

    You are missing a comma - please relook at my code, I am sure you will spot it.

    @WarrenBelz 


    Spotted the comma - I think I was looking at it for too long yesterday. I appreciate your help and patience.

    Merry Christmas and happy holidays 🙂
