Excel import overwrites data when using lookup and number column in composite key constraint

(0) ShareShare

Posted on by

Hi there, 

 

I have two tables in Dataverse as below

 

Clients table with the following columns

  • Name (Text, Primary Column)
  • Identifier (Number) 

Products table with the following columns

  • Name (Text, Primary Column)
  • Client (Lookup, Clients table)
  • Identifier (Number) 

 

I have created a key on the Products table which includes both the Client and Identifier columns. The intention of the key is to place a unique constraint which includes both the Client and Identifier. This is because Client A could have a Product with Identifier 123 and Client B could also have product with Identifier 123. 


Scenario

Given an existing row in the Product table with Client A and Identifier 123

When I perform a data import using the Import data from Excel button

And the excel file contains a row with Client B and Identifier 123

Then the excel import completes without errors

And the existing Product row will have the Client column updated to Client B 

 

Any ideas on how I can solve this issue? 

Regards, 
Jqueen2

    Hello, @Jqueen2, you will have to use the Name and Identifier in the Clients table as Alternate Key. Create Alternate Key in the Clients Table and Select both Columns. Make sure you select the alternate key when mapping the Excel columns in the Dataflow.
