Working on a SmartConnect map that will create a new GP project  / project budget using a SQL table as a source.  I am in the testing phase, so prior to running the map I set the associated Contract status to 4 prior to execution.
 
The map fails with an eConnect error of 6149, "Invalid Project Number (PAPROJNUMBER) - Project Number already exists in the PA01201 Table".  But there is no existing project in the PA01201 with the same number.  I even rebuilt the indexes on PA01101 and PA01201 to see if the issue was with an indexed lookup.  
 
Anyone come across this before?
