Hi @yuriarciniegas ,
What is the type of Dropdown field? LookUp, Text or Choices?
Could you share the expression of your Dropdown ?
Do you want to show all 752 value in your dropdown list?
Is there the blue dot warning Delegation warning can be found in the formula?
Maybe the distinct function has been applied to dropdown, as you can see from screenshot, the same values are removed from the list, so that the value of list is much less than 752.
Just change the formula of item property of drop down to: Choices(listname.lookupfiedname)
Another cause maybe the non-delegation, you could increase the default non-delegable row limit from 500 to 2,000 (max size).
Please follow the steps to set it: file – App settings – Advanced settings – Data row limit for non-delegation queries.
Best regards,
Sik
