Nested If Condition Problem

Hi,

I have this code which is used in the OnScan property of Bar Code Control,  I am actually scanning only those codes which have selected "S" as a Prefix  for Serial Codes.  and "1S" as Prefix selected for Product and Serial Together bar code.

I am using a dropdown called as Prefix Selector

The Condition is working for "1S"  and it's showing popup if the code is scanned again, it will show Duplicate Scanned, and if the different code is scanned it will show a popup >>> Not a 1S Bar Code Type

Issue:  But the code for "S" creating some issues, if the user scans the serial code, it stores and works good, but if the user scans it again it shows both Popups >> Not a Serial Code and Duplicate Scanned at the same time and if the user scans a different code while "S" is selected, it shows popup >>> Not a 1S Bar Code Type (This is not working as expected, what's wrong is in my statements ??)

 

If(ToggleIssue.Value=false && PrefixSelected.Selected.Title = Left(BarcodeScanner2_3.Value,2),


 
// Left(BarCodeScanner2_3.Value,2) is used because if the user has selected ("1S") Prefix, than it will match with it while scanning and store Serial code and Product information.
 
 

If(IsEmpty(Filter('Barcodes - Test',  BarcodeScanner2_3.Value = Title)), 

 
\\ The Above if condition will checks in the Database if there is an entry or not , at first it will return false and then it will patch the data into the databse, and if the scanned code is scannned again it will show a popup to the user as Already Scanned.
 

   Patch('Barcodes - Test',    // Patch Command
   
   Defaults('Barcodes - Test'),

 

   {
   SerialCode:Right(BarcodeScanner2_3.Value,8),
   'Product Code': Mid(BarcodeScanner2_3.Value,3,10),
   Title:BarcodeScanner2_3.Value,
   'Batch No': BatchSelection.Selected.Title,
   ReceiveCheck: ToggleIssue.Value,
   UserName:MyUser,
   ReceivedSatus: "Yet To Receive",
   When:Today() + Time(Hour(Now()), Minute(Now()),Second(Now()))    
   }
),Set(_DuplicateScan,true)),  // Duplicate Popup

 

If(ToggleIssue.Value=false && PrefixSelected.Selected.Title = Left(BarcodeScanner2_3.Value,1),
 
// Left(BarCodeScanner2_3.Value,1) is used because if the user has selected ("S") Prefix, than it will match with it and store only Serial code information.

 

If(IsEmpty(Filter('Barcodes - Test',  BarcodeScanner2_3.Value = Title)), 

 

   Patch('Barcodes - Test',
   
   Defaults('Barcodes - Test'),

 

   {
   SerialCode: Right(BarcodeScanner2_3.Value,8),
   Title:BarcodeScanner2_3.Value,
   'Batch No': BatchSelection.Selected.Title,
   ReceiveCheck: ToggleIssue.Value,
   UserName:MyUser,
   ReceivedSatus: "Yet To Receive",
   When:Today() + Time(Hour(Now()), Minute(Now()),Second(Now()))    
   }

 

),Set(_DuplicateScan,true),
 

Set(_NotSerialCode,true))   // if the user has selected (1S) and if he tries to scan a serial code, or any other code which does not match, it will show a popup, Not a S  Code
 
,Set(_NotISCode,true)))  // if the user has selected (S) and if he tries to scan a serial code, or any other code which does not match, it will show a popup, Not a 1S  Code

I might have misunderstood your original logic in your Formula.

Replace with this Formula:

If(ToggleIssue.Value=false,

    Switch(PrefixSelected.Selected.Title,
        // if the user has selected (1S) and if he tries to scan a serial code, or any other code which does not match, it will show a popup, Not a 1S  Code
        "1S", Set(_NotISCode, !(PrefixSelected.Selected.Title = Left(BarcodeScanner2_3.Value,2))),
        
        // if the user has selected (S) and if he tries to scan a serial code, or any other code which does not match, it will show a popup, Not a S  Code
        "S", Set(_NotSerialCode, !(PrefixSelected.Selected.Title = Left(BarcodeScanner2_3.Value,1)))
    );
    
    If(!_NotISCode && !_NotSerialCode,

        // Is it a duplicate?
        If(!IsEmpty(Filter('Barcodes - Test',  BarcodeScanner2_3.Value = Title)),
            Set(_DuplicateScan, true), // Duplicate Popup
            
            // ELSE - Patch Command
            UpdateContext({patchedRecord:
                Patch('Barcodes - Test',    
                    Defaults('Barcodes - Test'),
                    {
                        SerialCode:Right(BarcodeScanner2_3.Value,8),
                        Title:BarcodeScanner2_3.Value,
                        'Batch No': BatchSelection.Selected.Title,
                        ReceiveCheck: ToggleIssue.Value,
                        UserName:MyUser, 
                        ReceivedSatus: "Yet To Receive",
                        When:Today() + Time(Hour(Now()), Minute(Now()),Second(Now()))    
                    },
                    If(PrefixSelected.Selected.Title="1S",
                        {'Product Code': Mid(BarcodeScanner2_3.Value,3,10)},
                        {}
                    )
                )
            })
        )
    )
)

@MH3 

Some of your conditions are not met properly in the Formula that you have.

Consider the following formula to replace yours:

If(!ToggleIssue.Value,

    Switch(PrefixSelected.Selected.Title,
        // if the user has selected (1S) and if he tries to scan a serial code, 
        // or any other code which does not match, it will show a popup, Not a 1S  Code
        "1S", Set(_NotISCode, !(PrefixSelected.Selected.Title = Left(BarcodeScanner2_3.Value,2))),
        
        // if the user has selected (S) and if he tries to scan a serial code, 
        // or any other code which does not match, it will show a popup, Not a S  Code
        "S", Set(_NotSerialCode, !(PrefixSelected.Selected.Title = Left(BarcodeScanner2_3.Value,1))),

        // Switch Else condition
        // Is it a duplicate?
        If(!IsEmpty(Filter('Barcodes - Test',  BarcodeScanner2_3.Value = Title))
            Set(_DuplicateScan, true), // Duplicate Popup
            
            // ELSE - Patch Command
            Patch('Barcodes - Test',    
                Defaults('Barcodes - Test'),
                {
	            SerialCode:Right(BarcodeScanner2_3.Value,8),
	            'Product Code': Mid(BarcodeScanner2_3.Value,3,10),
	            Title:BarcodeScanner2_3.Value,
	            'Batch No': BatchSelection.Selected.Title,
	            ReceiveCheck: ToggleIssue.Value,
	            UserName:MyUser, 
	            ReceivedSatus: "Yet To Receive",
	            When:Today() + Time(Hour(Now()), Minute(Now()),Second(Now()))    
	        }
            )
        )
    )
)

 

I hope this is helpful for you.

Hi @RandyHayes ,

Actually, there are two patch commands,
One is for Product and Serial together code, which is "1S" Prefix Patch, 

and another is for Serial code only, where only "S" Prefix  codes will be patched.

 

can you help me into that? 

@MH3 

I thought I saw a difference at first, but then seemed to see no difference. Now I do.  Easy adjustment, here is the formula:

If(!ToggleIssue.Value,

    Switch(PrefixSelected.Selected.Title,
        // if the user has selected (1S) and if he tries to scan a serial code, or any other code which does not match, it will show a popup, Not a 1S  Code
        "1S", Set(_NotISCode, !(PrefixSelected.Selected.Title = Left(BarcodeScanner2_3.Value,2))),
        
        // if the user has selected (S) and if he tries to scan a serial code, or any other code which does not match, it will show a popup, Not a S  Code
        "S", Set(_NotSerialCode, !(PrefixSelected.Selected.Title = Left(BarcodeScanner2_3.Value,1))),

        // Is it a duplicate?
        If(!IsEmpty(Filter('Barcodes - Test',  BarcodeScanner2_3.Value = Title))
            Set(_DuplicateScan, true), // Duplicate Popup
            
            // ELSE - Patch Command
            Patch('Barcodes - Test',    
                Defaults('Barcodes - Test'),
                {
	            SerialCode:Right(BarcodeScanner2_3.Value,8),
	            Title:BarcodeScanner2_3.Value,
	            'Batch No': BatchSelection.Selected.Title,
	            ReceiveCheck: ToggleIssue.Value,
	            UserName:MyUser, 
	            ReceivedSatus: "Yet To Receive",
	            When:Today() + Time(Hour(Now()), Minute(Now()),Second(Now()))    
	        },
	        If(PrefixSelected.Selected.Title="1S",
	            {'Product Code': Mid(BarcodeScanner2_3.Value,3,10)},
	            {}
	        )
            )
        )
    )
)

@RandyHayes , Thanks for the reply.

 

I actually can't test your formula right now, because I am now at home, but I will notify you when I test it tomorrow.

 

and one thing more, if there is a requirement to incorporate more prefixes how can I adjust my code, do I have to make these logic all the time? like creating different patch and different trimming functions according to the prefix ? is there any dynamic workaround? or anything which can make the work easier? like a setup process? user will select right trim, left trim, mid if needed, and the prefix and according to that code work? is that possible just asking for future thing.

@MH3 

No problem, see how it works for you.

 

For adding additional prefixes, you would just add more into the switch statement.

Ex:

If(!ToggleIssue.Value,

    Switch(PrefixSelected.Selected.Title,
        // if the user has selected (1S) and if he tries to scan a serial code, or any other code which does not match, it will show a popup, Not a 1S  Code
        "1S", Set(_NotISCode, !(PrefixSelected.Selected.Title = Left(BarcodeScanner2_3.Value,2))),
        
        // if the user has selected (S) and if he tries to scan a serial code, or any other code which does not match, it will show a popup, Not a S  Code
        "S", Set(_NotSerialCode, !(PrefixSelected.Selected.Title = Left(BarcodeScanner2_3.Value,1))),

        "OTHER", Set(somethingelse, somecondition),
...etc.

 

Although if you have a lot of different prefixes to add, I would consider re-evaluating the notification mechanism so that you don't end up with a ton of variables and different pop up boxes.  This can all be combined into one.

Yes, @RandyHayes  you are correct.

 

will take your assistance in that problem if it persist :).

 

 

One last thing, there is a requirement from the customer that sometimes they have loss of internet connection and sometimes when they scans the code, it just not update into SP List..

 

is there any workaround for that, any offline capability? for my application like if the connection is not connected it should save the data and when the connection is up patch those records into the database or SP List. 

 

I have searched for it, but couldn't find anything and couldn't understand how to implement that, because I don't know much about collection. can you help me if you don't mind?

@MH3 

Yes, offline capabilities are not something that are built into PowerApps.  You have to formulate a process to handle them.

It usually involves a serious re-look at the process you have now.  

You would need to "centralize" your Patching processes to someplace else and utilize a condition check on the connection.  If it has none, then you would need to store the patch information both in a collection and saved to the local device.  Then when a connection is available again, your app needs to recognize that and then patch all the records stored while offline.

There are many ways to go about it depending on your scenario, but there is nothing built in that would allow you to just "switch" it on or off.

@MH3 

In reading some of your other posts and messages on your original subject, I might have some of the "if" logic backward as I read your original formula and now your posts.  

So, in general it should all work, but there might be a need to switch the logic around to meet your needs.

See how it goes when you get a chance.

I copied your formula, and it keeps giving error in switch statements, I tried to figure it out but got nothing!!!
