Hi
In addition to what Lohith has mentioned above, do check:
1) ST22 for any dumps around that time (the time of start of the step in workflow log) for user WF-BTACH. If a step goes endlessly in the status "In Process", there can be a dump
Also check Step History tab of that step in Technical WF log and see if there are any messages in there.
2) Ensure WF-BATCH has SAP_ALL so that there is no Authorization issue in RFC calls
3) Ensure that you can make RFC class to the desired system - the connections are open and are not locked
4) Check with your Basis team if there is any specific settings to be done on the target system to enable calls from WF-BATCH coming in from source system (where the workflow is).
