How to check duplication of the field value of CDS entity for more than 2000 records?

[dave8]

Hello,

I have an edit form connected with CDS Entity where one of the text fields needs to be validated for the duplicated value.

How can I check duplication of the field value of CDS entity for more than 2000 records?

Thanks,

Hi @dave8 ,

If you are looking to see if a text field in a particular record has a duplicate and want to avoid any Delegation Warnings, you could do this

With(
   {
      wDup:
      LookUp(
         YourListName,
         YourTextFieldName=YourTextControlName.Text,
         YourTextFieldName
      )
   },
   If(
      !IsBlank(wDup),
      Notify("Duplicate record")
   )
)

If however you are looking for any duplicates, I have done a blog on Delegation listing some options for large collection that would possibly do the job. Happy to elaborate further if this is what you are trying to do.
