Increment number without duplicating

Posted on by Caleb62881177 765
Hello,
 
I am trying to create an expression to generate incremented text numbers from a ComboBox that is connected to a Dataverse Choice column, without creating duplicate text numbers.
 
I was using this expression below:
 
DataCardValue7.Selected.Name & Mod(Year(Today()), 100) & "-" & 
   If(
      IsBlank(
         Max(
            Filter(
               Table,
               StartsWith(Column, DataCardValue7.Selected.Name & Mod(Year(Today()), 100) & "-")
            ),
            Value(Mid(Column, Len(DataCardValue7.Selected.Name & Mod(Year(Today()), 100) & "-") + 1, Len(TrialCode)))
         )
      ),
      1,
      Max(
         Filter(
            Table,
            StartsWith(Column, DataCardValue7.Selected.Name & Mod(Year(Today()), 100) & "-")
         ),
         Value(Mid(Column, Len(DataCardValue7.Selected.Name & Mod(Year(Today()), 100) & "-") + 1, Len(TrialCode)))
      ) + 1
   )
 
 
Below is the values of the ComboBox.
 
["Dave", "Joe", "John", "Emily", "James", "Joe"]
 
 
Below is the example of the output I am trying to achieve.
Example :
 
Dave25-1
Joe25-2
John25-3
John25-4
Emily25-5
James25-6
Joe25-7

    Just adding some input here, mainly to get rid of all that duplicated code. One other comment is your reference to column in the text part of the formula does not refer to a specific record. 
    With(
   {
      _Year: Mod(Year(Today()), 100) & "-",
      _Name: DataCardValue7.Selected.Name
   },
   With(
      {
         _Table:
         Filter(
            Table,
            StartsWith(
               Column, 
               _Name & _Year
            )
         )
      },
      _Name & _Year & 
      If(
         CountRows(_Table) = 0,
         Value(
            Mid(
               Column, 
               Len(_Name & _Year) + 1, 
               Len(TrialCode)
            )
         ),
         1,
         Max(
            _Table,
            Value(
               Mid(

    Hi @WarrenBelz, Sorry for responding now.
     
     
    This is my original formula 
    DataCardValue7.Selected.Name & Mod(Year(Today()), 100) & "-" & 
   If(
      IsBlank(
         Max(
            Filter(
               'AGTRS Trial Request Tables',
               StartsWith(TrialCode, DataCardValue7.Selected.Name & Mod(Year(Today()), 100) & "-")
            ),
            Value(Mid(TrialCode, Len(DataCardValue7.Selected.Name & Mod(Year(Today()), 100) & "-") + 1, Len(TrialCode)))
         )
      ),
      1,
      Max(
         Filter(
            'AGTRS Trial Request Tables',
            StartsWith(TrialCode, DataCardValue7.Selected.Name & Mod(Year(Today()), 100) & "-")
         ),
         Value(Mid(TrialCode, Len(DataCardValue7.Selected.Name & Mod(Year(Today()), 100) & "-") + 1, Len(TrialCode)))
      ) + 1
   )
     
    I am getting this error with the formula you have provided.
    Invalid number of arguments: received 3, expected 2.
     
    With(
   {
      _Year: Mod(Year(Today()), 100) & "-",
      _Name: DataCardValue7.Selected.Name
   },
   With(
      {
         _Table:
         Filter(
            'AGTRS Trial Request Tables',
            StartsWith(TrialCode, 
               _Name & _Year,
            )
         )
      },
      _Name & _Year & 
      If(
         CountRows(_Table) = 0
         Value(
            Mid(
               TrialCode, 
               Len(_Name & _Year) + 1, 
               Len(TrialCode)
            )
         ),
         1,
         Max(
            _Table,
            Value(
               Mid(
                  TrialCode, 
                  Len(_Name & _Year) + 1, 
                  Len(TrialCode)
               )
            ) + 1
         )
      )
   )
)
    I hope that helps

    Try this structure 
    With(
   {
      _Year: 
      Mod(
         Year(Today()),
         100
      ) & "-",
      _Name: DataCardValue7.Selected.Name
   },
   With(
      {
         _Code: 
         Filter(
            'AGTRS Trial Request Tables',
            StartsWith(
               TrialCode,
               _Name & _Year
            )
         )
      },
      _Name & _Year & 
      With(
         {
            _Max: 
            Max(
               _Code,
               Value(
                  Mid(
                     TrialCode,
                     Len(_Name & _Year) + 1,
                     Len(TrialCode)
                  )
               )
            )
         },
         If(
            IsBlank(_Max),
            1,
            _Max + 1

    Hi @WarrenBelz, Thank you for your response.

    The number doesn’t increment unless the value before the "-" is already present in Dataverse.
     
    For example:
     
    ["Dave", "Joe", "John", "Emily", "James", "Joe"]
     
    I get this
     
    Dave25-1
    Joe25-1
    John25-1
    John25-2
    Emily25-1
    James25-1
    Joe25-2
     
    Instead of that
     
    Dave25-1
    Joe25-2
    John25-3
    John25-4
    Emily25-5
    James25-6
    Joe25-7
     
    I hope this gives more clarity

    I would need to build a model, which I cannot do presently - @mmbr1606 might want to have a go at this.
