I have got a lookup field on an object, which I would like to update to Null/blank (remove the existing value) using FLOWS.

I have tried to use {!$GlobalConstant.EmptyString} but its not working, there is no null global constant in this format. However I was able to save $GlobalConstant.Null (without the braces) but still no result.

Can someone please help me with this?

Thanks

  • Did you try just leaving it blank with out any value? Commented Jan 11, 2023 at 5:22
  • This should work both with empty value and {!$GlobalConstant.EmptyString}. Did you check if you have added any condition while updating the record and also any custom logic that is populating it again? Commented Jan 11, 2023 at 5:32

All you have to do is leave the field value blank. I have tried as below:-

and i tried on record edit by activating the flow as well, it worked.

else, you can create a formula as well

    the final solution with formula worked...as I was un-assigning the lookup in a loop, other solutions are not working. Anyway will further look into it. Thanks @Sanket Commented Jan 11, 2023 at 6:52
