Hello Henrik,
This is actuallly not an NCo question, but a question about BAPI_XBP_ADD_JOB_STEP and whether the jobs modifed with this function module can be analyzed remotely. Therefore, I'd recommend that you have a look at function group SXBP. In this group, there are all related function modules, e.g. also BAPI_XBP_JOB_DEFINITION_GET, which I think is the one for getting the information you desire.
Best regards,
Markus
