In my application, the DB contains the fields (id,name,unit,type,isActive). The name and unit values are retrieved based on the type and shown in the UI dropdown and that is the List.
One Particular type contains 13000+ active records and gives Memory Threshold issue when it tries to load the data. In the expression rule, the batch size as set as -1 to retrieve all the data's from DB.
To avoid this exception, I added the batch size as 100 in a!pagingInfo(). But the problem is now able to see only the 100 records in dropdown field and not all the 13000+records.
Is there any other option is available to resolve this problem.

Hi Martina,
Did you try to create a record type on this and call this data from the record picker as that is very fast. i had the same issue but when i turned that to a record picker it was fast.
After using casting also, couldn't get the values in the desired format and only null values.
local!test:
What are we looking at here? When you read the documentation here
- https://docs.appian.com/suite/help/22.4/Custom_Picker_Component.html
- https://docs.appian.com/suite/help/22.4/recipe-configure-an-array-picker.html
This includes all required info.
When you explain what you tried and provide some code snippets, we can support you in a better way.
Hi Stefan,
I am Changing the dropdown field into Custom picker due to the Memory Threshold issue.
The custom picker is inside the Editable Grid. After selecting the custom picker, the remaining values should be displayed. When I tried the below code, the corresponding row result is null.
