I am using Extract & Load in Natural Engineer 6.1.1 and the JOB fails with the return code 255. I am getting the error “NATURAL Source Code (not found) Extract unsuccessful completion”. The job fails in step EXTRRUN. please help me in solving this error. If I am using the parameter DATSIZE=512, this will be solved, if so where I have to use this parameter. I am submitting the job from Natural Engineer running in windows environment and connected to the mainframe. ---
