Case Mgmt - Process - No provision for passing parameters to "Start When" when rule
In 8.5.1, is there provision to pass parameters to when rule specified in "Start When" field of a process in a case type.
E.g. create a when rule called as StartTask which accepts a parameter id_when. When rule then uses this parameter internally to decide whether process should be started or skipped.
When this when rule is specified in process in case type, Pega doesn't show the parameter. See attached image.
This is a severe limitation to reusability.

Hi Shrikant,
Instead of passing the value as a parameter, why not try to read the value from the case clipboard directly or source from a decision table or dss or data page (using functions) in the when rule
Thanks

We want our case to hold just the transactional data it needs to process a case. Moreover, even to read from decision table or dss, we would need "source" or some kind of "input", which is nothing but a parameter.
E.g. if passing parameter is possible, we could configure case type to pass parameter for each step as below
StartTask [parameter: task1]
StartTask [parameter: task2]
Internally, StartTask when rule can look at decision table or even a data page to decide whether task1 or task2 should be started.

Hi Shrikanth,
Within the when rule, using expression builder I think you should be able to
