Batch

Hi,

I need to check whether the changes are online or background. For this, iam using sy-batch to check. if sy-batch eq ' ' --> it is online otherwise it is background.

This is working for online changes but sy-batch is not updating when iam using background. In back ground, sy-batch should update as 'X'. Its not happening thus creating a problem..

Can anyone help me whether is there any other procedure to check whether it is online or background????
