RFX Approval based on the target Value

Hi Experts,

I am setting up the BRF workflow, where the requirement is that when the RFX Float value is more that some x value it should go to some certain approver.

I checked in the table and i found it that the target value stores at the header table BBP_PDHGP-target_value.

Now I tried to find out the existing expression on T-Code BRF, I didnt found any expression related to that.

Please guide me step by step how to get that value and based on that value my approver should change.

Thanks & Regards

Anand
