DSXchange

This job has a sequential file a copy stage and an Oracle Enterprise stage. I have parameters setup for the input file name on the copy stage, the user name, password and instance name in the Oracle stage. The job ran fine in the past. Now I am getting the following error:

main_program: Parameter not resolvable: DSProjectMapName
main_program: Parameterization Error: Parameterization failed.

Any help is appreciated.

What has change in the system or environment?
