I want to update the approval status column in my entity record for the specific entity record.
I require help in defining the rule under create or update entity records in my app.
In this context, is Request_Master in the scope of some DataContext? What’s the structure of this Entity? Is approval status a string or something else?
The expression you’ve written seems syntactically valid, but I don’t think it’s doing what you want it to. If you share your exported .uiapp I’m sure I can help 
(Feel free to DM me if you don’t want to share it publicly on the forum)

I may be wrong as I haven’t done this, but it seems to me that he is trying to use the “Update” part of the Create/Update Entity record function. To do this, I believe you need to use a Lookup(Request_Master,[Condition]) in the topmost field and in “Values to set” you simply add the value.

I want to update a specific column of entity record and for that, I am using the “Update entity record” activity but the same is creating a new entry instead of updating the entity.
Were you able to find a solution for this? I’m experiencing the same issue.
The layout has changed since this topic was created, but the functionality is the same.
In order to update a record, you need to first lookup the record but either building the fetchOne expression or take it from an fetch activity and use the record.Id as the input to the update activity.
In the image under, only two of the columns are being updated.
