Mismatches between labor, craft, skill level, vendor and contract are not allowed. Use the Select Value lookup to see a list of valid choices

If you have been playing around with the Maximo Enterprise Adapter (MEA) or even the Integration Framework in Maximo 7, and you have tried to load labor transactions against a workorder, you may have encountered this very random error:

Mismatches between labor, craft, skill level, vendor and contract are not allowed. Use the Select Value lookup to see a list of valid choices

It’s not a very intuitive error when you realize the cause of it.  This error states that there is a mismatch between the labor and craft.  Even if you specify the labor’s craft in the inbound XML, you will still get this error message.  No matter what you do to the XML or labor or even craft values, you will still keep getting this error.  This error took us days to figure out in Maximo 6.2, but we eventually got it working and it wasn’t because of the labor code and craft mismatch.
