How do I Enable Approve and Reject buttons for Shopping Carts in SAP Fiori My Inbox

Hi Fiori Folks,

I have to enable Approve and Reject buttons for Shopping Carts in SAP Fiori My Inbox and I have already the following tasks, but still not able get the Approve Rejects for SC workflow items in My Inbox.

1) Maintain Task Names and Decision Options

2) Implemented the BADI '/IWWRK/BADI_WF_BEFORE_UPD_IB' based on information from the earlier blogs, but the external break-point is not getting triggered.

3) And the component versions we are in are

     a) IW_PGW     100     008

     b) UIX01CA1    100    005

     c) UIX01SRM     100    007

     d) GBSRM001   700    0016

     e)SRMNXP01    100    0009

4) Workflow definition: WS4000001 and Task TS40007953.

Thanks in advance

Regards

Ramesh
