Creating a batchjob with parameters in AX2009


I would like to create a Batchjob with some order finishing tasks. When creating this i run into a problem - when klicking on parameters on the task “SalesFormLetter_PackingSlip” everything is greyed out - the user is a member of the Admin group. I have been able to do this for a couple of years ago so I think that I’ve made a fuckup with the rights

When excecuting SalesFormLetter_PackingSlip from the menu there is no problem in setting the parameters and putting that in batch.
