Could you provide more details on what you are trying to achieve? All the data tables are defaulted to local storage in express. So, in order to update the records, you have go to records tab in the data table and update the entries manually. You can reference a data type in a case using data references. You could use configure form on a a step in case designer to configure the same. There is no way you can update the values of the data table in the runtime directly. Hope this helps.
I am working on the pega express and created the data table with the properties.In the application I used these properties, but when the run time all these properties which I used are populated as Null and having no chance to enter the values.
But I want to enter the properties during run time and want to store in the data tables.
How are you using these properties in runtime? Did you associate the data type as part of a case's step? If you did, it values will be stored as part of the case data. I dont think there is a way to store the values in data tables directly.
I didnt find any option of creating the page of data type in the case type class. In pega express we have the configure form which we can give the page name to refer the properties. I did like that. While running the case the properties which i refered in the case in the configuring form are showing as read only. No chance to enter the data.
