Can we achieve transient Page List property functionality?
We are loading one of the property in our work class using parameterized data page (this data page makes SOAP service call which is heavy).
As we can load this property via data page when we want, we don't want to save this property to data base.
The advantages we have if we achieve this include :
- We can load this property only when needed.
- Calling @hasMessages() fn on work page is causing the data on property to reload. We want to avoid this.
Removing property from work page once there is no need for it would work. But we have already used this property in many places and it is tedious to track usage of this property and to code its removal.
Request you to suggest alternatives.

Hi Santhosh,
I think checking 'Do not save property data' attribute on property's advanced portal suits your requirement (Pega 7):

Hi Murali,
Thank you for the reply.
For a Page List property the advanced tab looks like below.

Ok, now I understand why you didn't see this option earlier.
This attribute is available only when data access is set to 'Manual' (for Page List property). When I set data access to Refer to a data page this option is not available!!!

In help I see following about data persistence but on rule form I do not see those attributes. My Pega version is 7.1.7.

Hi Murali,
Thanks a lot for the help!
We are in 7.1.8.
Interact directly with automatically loaded data pages might got renamed to Refer to a data page.
But even if we choose Refer to data page option the data is persisted in the database.

Hi Santhosh,
You can check your refresh strategy for your data page, in order to use 'Refer to data page' option based on whether the data page is set at Node/Requestor/Thread level(s)?

Hi Habeeb,
We are using data page with thread scope.

Hi Santhosh,
You can check the refresh strategy in 'Load Management' tab, depending on that you can verify when was the last time the Data page was available on clipboard and when it will be available next as per the refresh strategy. However if you select 'refer to a data page' you may always get a fresh data from database instead of previous/persisted data.
Please make you sure you select option as below in your property.

Hi Habeeb,
Our property configuration looks like below. Checking Save parameters with this property for access on open causing the property to persist on database.
Unchecking this option solved the issue for now. We are testing all scenarios. I will share results once we are done.
