I am working on a requirement where I need to show the read only grid to the user and user will be able to filter the data. I need to show the sum of filtered column values also to the user.

I was trying to cast the record type to CDT in the following way but it was showing castInvalid:

cast(
typeof('type!{urn:com:appian:types:INV}CDT_NAME'()),
recordType!recordName
)

Hello Pankaj,

You can cast in the following manner:

'type!{urn:com:appian:types:INV}CDT_NAME'(

field1: rv!record[recordType!recordName.field]

)

Hi Vinay,

We cannot use rv!record inside rule. It gives the error - Could not find variable 'rv!record'

This is specific if you are trying to create a record type and passing the cdt to your interface.

I'm unclear what you are trying to do - it shouldn't be necessary to cast a records grid to a CDT to show what you need. Can you describe more about your use case? What is the expression for your grid? Can you give an example of showing "the sum of filtered column values" in you grid?
