WE05 - run background

Hi all,

In WE05, in you go to menu 'Program', you see option like 'Execute'. The 'Execute and Print' option and

'Execute in Background' are greyed out.

I like to run this program in the background as i need to read to status of the idocs that are flagged 51 with errors, then send an email out.

Have anyone come across on how to set this WE05 to run in the background ?

thanks

Joyce
