This is a known issue. Since you made a change to the data page you will need to clear the contents of that field and re-enter the D_HRPlanList again. Once you do this you should see the parameter field and you will be able to enter Param.Type in the field.
As my laptop does not support virtualization, so i'm looking for any alternative to VM. Is it possible for Pega to provide rulesets, applications, other artifacts that we can import on local pega environment. I think it would be of less size and useful for large number of users who want to practice SSA.
The issue we have with providing the initial import is that we want to make sure the version of Pega you are using matches the version the course was designed on. SSA was designed on Pega 7.2.1. Do you have access to that version? Can you confirm by including a screenshot. I want to make sure the exercises will work as designed.
Is there any way you can request a laptop from your company that does support virtualization?
