It seems to me there used to be a standard save button on perform harness. I am now using PRPC 8.1.2 and I do not see a standard save button on perform harnesses anymore. I could be wrong and just don't know how to enable it. Yes I suppose I could place my own Save button on but I would rather use ootb pega for it. Was the Save button taken away for some reason? If its still there how do I enable it? By default it is not showing.
By default flow action enables pyCaseActionAreaButtons nevertheless If you enable hide default buttons on flow action level setting, in that scenario you need to add customized button in respected section(Save, Cancel, Submit). Please verify you settings once
I am able to see generate assignment button . Is it the save button which has been modified?
Please use the perform harness form the Enduserui/UI kit and save it to your application reulset , then run a case which have atleast one field defined in it.(you can try creating a new case for testing purpose) and then check if you are able to see the submit/save button or not.
