Hi Rishub,
Updating CDT in running instances can be achieved using the Process upgrade.
forum.appian.com/.../Process_Upgrade.html
Also there are various forum posts related to the similar context :

Hope it helps.

hey Sonal, This is not the existing instance. I need to use it in process model for new cases.

@rishub I believe when you do a impact analysis, it should take care of the places where the CDT is reference to get the newly added element to the CDT.

If your CDT instances are in an array, can you use the apply() function?

For example:
apply(
          rule!applyNewTime(
                    value: _
          ),
          index(accountCDTs, <ordinal position of UpdatedTime field>, null)
)

Hi Rishub,
Process models will be updated by performing the impact analysis available in the Appian designer, selecting the CDT and on the right hand side drop down
values you can find "Check Outdated dependents" and it will updated all the related dependents including process models.

Go through the below post, it will give you an idea. forum.appian.com/.../e-187277
Using Display Cdt rule, we can update the Cdt fields, or there
Is a custom plugin in forum which will update the Cdt fields.

Guys, I think there is miscommunication here. Basically, I am creating a process model in which I query a CDT, I get values for a couple of fields from query (The result is in multiple). Now I need to update rest of the fields from PV's. For example, there is CDT say Account with three fields AcctNo, AcctName & Updateddate. When I query Account, I got AcctNo as 1,2,3 & AcctName as A,B,C. Now I need to update the third field of CDT by using now() function. I don't want to use MNI to update CDT. What can be the best way to do it without using MNI?

Have you tried this forum.appian.com/.../summary

The updatecdt function should help you.

Map the CDT.updateddate to 'repeat(length(CDT.AcctName),now())'
