Hi Roland,
yes your right if one job is running , other job runs means that will be error .
but see if one job start at 2 o'clock and that will be end at 4 o'clock. copied job will start at 4.09 like I have to run in multiple times . I can do that one manually but we have to automate this one.
if we schedule any process chains that will give the standard job BI_PROCESS_TRIGGER if you copy this job and make other schedule time, no problem it wont lead any issue .
Regards,
Polu.
