tMDMOutput cannot insert records when i check 'Is Update'
When i check the 'Is update' , it gives me an exception when i try to insert new records .
The exception is : cannot update document ... with id ... because it does not exist.
You ticked "Is Update": MDM expects you're updating an existing record. Since MDM can't find the record you wish to update (which is expected in your case since you're creating the record), it throws an exception since "Update" doesn't have the meaning "Update or create".
Does the non Primary Key fields get updated at entity level without using any join (tXMLmap)/comparison and just by ticking the IsUpdate option in tMDMOutput component?
