Hi,
I am trying to import data from a CSV file into a Dynamics 365 Account table. As I need to do some transformations I am using a dataflow rather than a basic copy activity.
I was having difficulties getting it to work using a dataflow for writing to a multi lookup field so I tried using a copy activity to see if that worked using the exact same source,sink and mappings. I was able to import the data successfully with the copy activity. I'm confused as to why the data flow does not work using the same source,sink and mappings. Below are screenshots of the various elements I set up and configured. Would appreciate any suggestions to get the dataflow working.
I'm using a cut down version of what will ultimately be my source CSV file. This is just so I can concentrate on getting the writing to the lookup field working.
Source CSV file
Copy Activity Source
Copy Activity Sink
Dynamics 365 Sink
Dataflow Source
Dataflow Sink
Copy Activity Mapping
Dataflow Mapping
Copy Activity Success
Dataflow Failure
Dataflow Error
