SC Workflow: Runtime Actual Approval determination

Hi all,

I want to know who approved the Shopping Cart (SC) in runtime within the BADI so that comparing his Approval Limit with the cost of SC I can decide whether to skip or go for next approval levels.

Please help how to find it out. I have checked the history table but it contains a field "Type" whose possible values can only be either "changed" or "insert" and does not indicate "Approve" status for any agent....

Please help,

Thanks
