Unable to get the log for Suspended process in BPM

Hi All,

We are integrating SAP BPM with SAP BRFPlus.

We created a rule in a BRFPlus function and converted that function as a RFC.

Now we imported the RFC into BPM process and did the subsequent settings as per the blog

Calling ABAP RFC in CE BPM 7.2

But when we check the process,it shows to be suspended and when we try to resume it it still goes in error.

in the BPM we did not create any activity other than one automated activity hosting the RFC between start and end steps.

Can you please guide me where to check the error log and how to resolve this error with automated activity?

Checked most of the articles and blogs on SDN but did not find any answer.

Please help me.

Thanks in advance
