how to change the publish parameter values for each run in fme server ?

Hi Team Fmeiers,

I wanted to change the publish parameter value in fme server for each run. for example

existing system we have is:

fme desktop,in my fmw file the buffer value is published. and every time i run thru batch file, i can change the buffer values by editing batch file.

fme.exe c:\\temp\\create_road.fmw --buffer 50

fme.exe c:\\temp\\create_road.fmw --buffer 100

fme.exe c:\\temp\\create_road.fmw --buffer 150

here the bat file calls the same fme workspace three times with different buffer values.

calling this batch file windows scheduler , three different time intervals.

upgraded to fme server 2017

Now, this fmw file is published in fme server and this job is scheduled in server three times a week

how can I achieve the same task using fme server.

your help will be appreciated.
