@Yoursnani ,

So you want to update different fields? That is not possible with an Update command as the data source of the card needs to be set. You are better off simply using a Patch command.

Hi @Yoursnani ,

Dynamic Items of a Form require both datasets to have identical field names and field types and even then, I have found they do not always work properly. You might consider simply having two Forms (one on each list) with the Visible set according to the choice made.

@Yoursnani ,

What are the Items and names of (both) the drop-downs and what is the name and type of field you are updating?


Items are List (both)

1st List names  : project WBS Elements

  • 2nd List Name : project WBS Elements -Deisel


@Yoursnani ,

I need the Items and names of the drop-downs



Dd name :Dropdown1 

Item name : project WBS Elements (its List )

Value should came : Active WBS Element (its column)

DD2 name: Dropdown2

item :Project WBS Elements -diesel (its List)

 Value should came : WBS Element -Diesel (column)

@Yoursnani ,

Are you updating the same column here or two different columns? Also is this a drop-down or a combo box control?

I am a bit lost here what you are trying to do - can you please explain in more detail.


I have total three list they are analytical, project WBS and WBS diesel.


I am creating a app in analytical list 

and I want to pull data from project WBS and WBS Diesel . when I choose choice GAS  its need to pull data need to come from Project WBS list and when I choose choice Diesel data should be pull from WBS Diesel list. When I I am trying to use "IF" functions in drop down . its not showing all columns in value .

Then I try to create two drop down for single columns. And I put different item functions . its works but when I am going to save . its getting error in Update property  for the that particular column. can you have suggestion on this . what should be update functions.
