Lookup entry in list

[AaronHB]

So I know it should be possible to have a lookup that looks to see if a entry is there, if there is it will not do anything and if nothing is there that matches then it will add an entry.

So far I have tried this: "Patch(Inventory, LookUp(Inventory,Barcode=BarcodeScanner2.Value),{Barcode: BarcodeScanner2.Value, 'Last person to scan': User().FullName, When: Now()})"

But I realized that this would just look for the scanned barcode and just change the values.

Thanks,

My suggestion is to use a conditional statement to check if the record can be found using a combonation of the ISEMPTY and LOOKUP functions

If(
    IsEmpty(LookUp(Inventory,Barcode=BarcodeScanner2.Value)),
    Patch(
        Inventory,
        Defaults(Inventory),
       {
           Barcode: BarcodeScanner2.Value,
           'Last person to scan': User().FullName,
           When: Now()
       },
    Patch(
        Inventory,
        LookUp(Inventory,Barcode=BarcodeScanner2.Value),
       {
           Barcode: BarcodeScanner2.Value,
           'Last person to scan': User().FullName,
           When: Now()
       }
)

Hi @mdevaney 

I have tried this and it seemed to send something to sharepoint, but I am looking at the list and what I just scanned is not there.

I have double-checked and yes this did not work.

Which scenario are you testing?  New barcodes or editting barcodes already in the system?  

What does Barcode2.Value evaluate 2 when you put it in a label?

[AaronHB]

Hi @mdevaney 

I was adding a new barcode and the value is the name of the device.

I think I need to slightly change my earlier code.  Try this instead...

If(
    IsBlank(LookUp(Inventory,Barcode=BarcodeScanner2.Value,Barcode)),
    Patch(
        Inventory,
        Defaults(Inventory),
       {
           Barcode: BarcodeScanner2.Value,
           'Last person to scan': User().FullName,
           When: Now()
       },
    Patch(
        Inventory,
        LookUp(Inventory,Barcode=BarcodeScanner2.Value),
       {
           Barcode: BarcodeScanner2.Value,
           'Last person to scan': User().FullName,
           When: Now()
       }
)

Other Questions:

What does Barcode2.Value show when you put it in a label? (After scanning)

What does IsEmpty(LookUp(Inventory,Barcode=BarcodeScanner2.Value,Barcode)) show if you put it in a label?

Hi @mdevaney 

The barcode value in a label is the barcode, so the name of the device.

And the second it shows false.

Hi @mdevaney 

I have changed what you sent form IsEmpty to IsBlank, as it was looking for an empty entry whereas blank checks to see if the value is there. This seems to have worked.

If(
    IsBlank(LookUp(Inventory,Barcode=BarcodeScanner2.Value)),
    Patch(
        Inventory,
        Defaults(Inventory),
       {
           Barcode: BarcodeScanner2.Value,
           'Last person to scan': User().FullName,
           When: Now()
       },
    Patch(
        Inventory,
        LookUp(Inventory,Barcode=BarcodeScanner2.Value),
       {
           Barcode: BarcodeScanner2.Value,
           'Last person to scan': User().FullName,
           When: Now()
       }
    )
  )
)

Thanks for the help though.

OK.  I've changed the IsEmpty to IsBlank in my post.  Please mark the thread as closed.
