In process definition it is possible to configure parameters. These parameters are entered by user at process start and can be later used for IWS system selection.
Process definition parameter can directly contain IWS system name and this value is then used by IWSz process environment.
For example we have two IWS systems IWSA and IWSB. To process definition we define parameter IWSYS with two possible values IWSA and IWSB. To process environment for ProcMan activity we define usage of parameter IWSYS this way:
Process definition parameter can be used indirectly as key to IWS systems list. This approach is reasonable for configuration with more IWS systems and more ProcMan activities. In process environment are used two settings tws_source_system_selected_index and tws_target_system_selected_index.
For example we have four IWS systems IWSA, IWSB, IWSC, IWSD. One process definition parameter GROUP has values TEST1 and TEST2. In process environment we specify usage of IWS system workflow:
data from IWS system IWSA are copied to IWS system IWSC
data from IWS system IWSB are copied to IWS system IWSD
