Sync Record Smart Service how to work

You need to use the primary key of the TEST_REG record type as the identifier.
Does '1' represent a primary key for any record?
Additionally, verify that the data type of pv!identifiers matches the data type of the TEST_REG record type's primary key.

The field "Record Type" is named like this, because it expects you to pass a reference to a record type. Use "recordtype!ABC_YourRecord" to do so.

BTW, the documentation is pretty clear on how to use this smart service.

Thanks, it worked for me

spykid  For future reference, could you tell us what the issue was?

Yeah agreed with Stefan - you should just pass in the record type directly. I think it's really unlikely that you would need a process variable for the record type, since you don't really need to dynamically choose the record type to sync here.

Also even though the message mentions "Invalid record type [identifer=]", this actually has nothing to do with the "identifiers" parameter, it's just saying that your record type isn't provided.
