Batch job parameters are going to non editable mode every 4 to 5 days of time....?

Hi All,

I have a batch job in AX 2009 for which its parameters are changed to non - editable mode after 4 to 5 days and if we need

to change the parameters, we need to recreate the batch job.(I do not want to recreate the batch job I just need to edit the

parameters when ever I want)

The batch job is created by using the "SalesFormLetter_Invoice" class as its task. the parameter form for this class is

same as the SalesTable (Form) --> Posting (B) --> Invoice.

The parameter form name is "SalesEditLines". I am not sure why all the controls in this form are non - editable after few

days of batch job creation.

Please let me know your ideas to fix this issue.

Thanks in Advance...!
