Need help patching a new record to CDS via patch for lookup field. I am mirroring the solution from :; however not successful...


Entity: Asset

Lookup Field: Asset_Location

ComboBox1: (Choices(Assets.Location))


Formula: Patch( Asset, Defaults(Asset), {Asset_Location: ComboBox1.Selected})


Result: Location field is blank.

Hi @FunGuy ,


The Items property of the combo box should be:



Please remove "()" and try again.


And for Patch formula, it seems that you only included the "Asset_Location" field. Please make sure that all the Required fields are included in Patch.

I was able to patch the other fields required THEN patch the appropriate lookup field to that record; however, I am unable to execute them together in one patch line. Is it possible to make it all one execution given that the lookup requires an existing record?



Patch(Asset, Defaults(Asset), {Asset_Name: "Test123"});

Patch(Asset, Lookup(Asset,Asset_Name="Test123"), {Location: Lookup(Locations_Table, Location_Name=Combobox1.Selected.Location_Name)})


Is it possible to store a lookup value (not as a text) in a collection?

I was thinking maybe Collect all the input data then use ForAll function to patch the specific lookup values.
