Debugging running transactions in NWBC

Hello All,

We are trying to debug the code that runs a transaction when using nwbc (SAP Business Client). We are not running SAP Easy Access but entering the transaction code on the NWBC screen shown as soon as you authenticate. We are unable to find the right class/program/function module where we can add the breakpoint to troubleshoot.

Appreciate if anyone can help with this.

Thanks,

Srini
