"Approval step without ad-hoc capability.No preview possible"

Hi,

We have implemented Nstep workflow WS14000133 with BADI.We have added an aditional Approver to the proposed startegy of approver . The workflow is working fine with the use of Z tables and is picking the correct approver but whern i see the appoval previe i am nor able to see the approval names and am getting a message "Approval step without ad-hoc capability.No preview possible.".

I am on SRM 5.5 as an add on to ECC 6.0 and we have applied SP10. Can anyone help me with this.

Regards

SRM Team
