I'm trying to add some additional fields to a tMap, I've added the fields to the appropriate schemas, but whyen I try to run the job I'm getting type conversion errors, not because I'm mapping to the wrong data types, but because while the data on the 'left' side of the tMap is as expected, on the 'right' side its mapping the data with an offset of the number of fields I've added. Even though I've added these fields to both schemas and set the mappings.
Is there a step I'm missing?
I'm mapping from mssql to salesforce, if that has any bearing.
Are you using the Automap tool? If your names on the input and output aren't identical, it will create new fields in the output table after the existing ones. I'm not sure if that's what you mean by "offset", but if so, make sure your names match, then run Automap again.
