Help with syntax please: AddColumns and LookUp with Azure SQL DB

The following code is underlining the = sign in red:


AddColumns('[Order].[OrderDetail]',"MyMenuCategoryID", LookUp(LocalMenuItem, MenuItemID = '[Order].[OrderDetail]'.MenuItemID,MenuCategoryID))

I am trying to add a column to OrderDetail. OrderDetail is a SQL Azure DB table containing a field MenuItemID. I want to find the corresponding CatergoryID for the MenuItemID in a collection named LocalMenuItems. Can't seem to find the right syntax 😞


Can someone point out what I'm doing wrong please?

Which part has the red line under it, and what does the error message say?

Only the = sign is underlined and the message is Invalid Argument type.

Finally figured it out 🙂 :


AddColumns('[Order].[OrderDetail]',"MyMenuCategoryID", LookUp(LocalMenuItem, MenuItemID = '[Order].[OrderDetail]'[@MenuItemID],MenuCategoryID))

Where have you written that piece of code, in a gallery's Items-property, or perhaps in a call to UpdateContext() in a screen's OnVisible-property?


It's probably just a typo, but just want to point it ouf it it's not: in the code you write LocalMenuItem, but in the explanation you write LocalMenuItems with an s on the end.

Thanks @BitLord69 - it was just a typo in my explanation.


I'm now trying to do similar with a LookUp to an Azure SQL DB table rather than a local collection:


AddColumns('[Order].[OrderDetail]',"MyOrderHeaderName",LookUp('[Order].[OrderHeader]',OrderHeaderID = '[Order].[OrderDetail]'[@OrderHeaderID],OrderHeaderName))

This is 'working' but is showing as non-delegable - specifically the = and the [@OrderHeaderID] are underlined blue.


Any thoughts on why this would not be delegable? OrderHeaderID is an int data type and in the OrderHeader table is an identity field (1,1).

Hi @PaulD1 any update on this issue? I'm also showing the non-delegable blue line on the '=' sign and the [@xxxxxxx] column field. 


Thank you

Hi @sdiaz


Are you using Azure SQL DB as your datasource? If so, I'd advise creating a View in SQL and using that as your datasource to get around this issue.


Note that I believe Views are still not updatable from within PowerApps, so if you are performing updates to your data, you have to Patch updates to the individual tables and refresh your Datasource (based on the View) to see those changes.

Hello @PaulD1 thank you for your reply. I'm using Sharepoint list as my datasource. 


The part of a longer formula that is giving me a headache is this one. 


AddColumns('Daily Shipping Table',"Core / Non-Core",LookUp(Materials, MaterialNum = 'Daily Shipping Table'[@MaterialNum],CoreNonCore)


In there, the equal sign and the [@MaterialNum] is giving me a delegation warning. Any thoughts with Sharepoint List?


Thank you

Hi @sdiaz


You could check whether using a First(Filter combinations makes any difference instead of LookUp (I don't think it will, but worrt a try), e.g.


First(Filter(Materials, MaterialNum = 'Daily ShippingTable'[@MaterialNum],CoreNonCore)


Failing that... You could cache Materials locally in a collection and use that instead. This is a common trick to boost performance but remember you will need to add a facility to refresh (ClearCollect) the collection to keep it up to date.
