Hi Lukas,
The answer is yes. It is possible to have two applications for Work Manager, one for the Customer Service module and another one for the PM module.
In the SMP administration console, create two agentry applications, one pointing to the Customer Service app, and another pointing to the PM module.
Remember to activate the appropiate BC Sets.
At transaction SCPR20, activate the following BC Sets:
/SMERP/SAP_WORK_MANAGER_61_REF, /SMERP/SAP_WORKMGR_61_EHP5_REF --> Work Manager 6.1
/SMERP/SAP_CUST_SERVICE_20_REF --> When activating the Customer Service component
After activating the BC Sets, you should see the following Apps configurations in t-code: /n/syclo/configpanel
Also, in the SMP 3.0 SP04 you have to set the parameter urlPath in the App specific settings. If you got 2 Apps, the first will always be defaulted to *SAPWM. I recommend to set a name that differs the purpose, like WMPM and WMCS.
Best Regards,
Emanuel
