Datamap Field Source Expression to Prevent Upsert on Existing Records or Ignore for Insert?
Hello,
I'd like to user EAI/Datamap for a specific requirement to insert some child records on an object from another source.
- I do not want it to fail due to existing records not being present (as with Insert method)
- I do not want to update existing records from the source (as with Upsert)
Is there a Data Map Source Expression that can be used to tell the process to ignore records already present in the target data set?
