20Hi,
I am looking to use Azure Data Factory to import a number of users from a third party source CSV file into the D365 user table/entity. This is usually straight forward but on this occasion I have a complication. The D365 users table/entity is already populated. The source CSV user file will have a mixture of users that are already in the D365 table/entity and others that are not.
What I would like to do is ensure the users in my source file that are already in the D365 table are not copied over as this would create duplicates.
Source CSV FILE
Existing D365 User table (subset of fields just to illustrate)
Updated D365 table with two new record added from source csv
From what I can see there are two possible solutions in Azure Data Factory
1) Configure the D365 sink to do it. e.g configure the sink in order to ignore records that match on a certain column? Is it possible to configure the sink in some way to accomplish this?
2) Pull in the D365 table/entity as a source and use it to filter my source CSV to remove user records that already exist in D365 perhaps by using a common field such as fullname to identify such records. This would ensure I only try to import new users.
I have had a look into both methods but have been struggling to find a way to implement them.
I'd like to think the scenario I have outlined above is not uncommon and there are tried and tested methods to filter out records from a source CSV that already exists in the target D365 table?
I'd appreciate any help/suggestion to help me achieve this. Thanks
