DataStage-SAP BW parameters error

[Hugot]

Hi all.

I'm working with server jobs and SAP BW. There were some jobs that work propertly between SAP BW and DataStage, and I'm using this project to create new server jobs. I can create new server jobs and generate them without problems, even I can create infopackages from BW using PULL data load method. The new info package is created in BW and I can see it. But when I try to refresh the variables in BW returns me this error: 'Error connection closed: no data'. If I do the same with the previous jobs there's no problem the parameter appears and everything works propertly.

I suppose something is not updating propertly when I create new jobs, maybe a file related to parameters or something like this. I've observed when I create new parameters in parameters tab a padlock appears.

Any idea about what is happening?.

Appreciate your help.

Thanks a lot.
