I want to add Record ID field for duplicate check while importing a list of records.
Thanks & Regards,
Sorry yes... that is more concise I agree. Well corrected Jeroen.
Sundar I am just now updating via .csv into our Serial Number custom module.
As Jeroen says I am selecting "create new records AND update existing records"
In this .csv I set the ID field as the Name so we end up with the ID being the same as the name, aka the printers serial number is the ID.
If that ID already matches an existing records ID it will update that record.
If the ID does not match another ID then the record will be created.
Hope that helps.
