Problem in deleting a row in a gridRowLayout

You need to save deleted row PK ids into a rule input and pass those values to process. In your process use delete data store entity smart service to delete those record using those IDs. 

You can use below logic to save your deleted IDs

link: a!dynamicLink(
  value: ri!clickedRow,
  saveInto: {
    if(
      a!isNullOrEmpty(fv!item.id),
      {},
      a!save(
        ri!deletedIds,
        append(
          ri!deletedIds,
          fv!item.id /*Primary Key of that row*/
        )
      )
    ),
    a!save(
      ri!data,
      remove(
        ri!data,
        ri!index
      )
    )
  }
)

FWIW, It's usually advised not to just delete a DB row like this (especially with "1-click" functionality from which there's no return); instead, you'd use more of a "deactivate" pattern where you have that row's dynamic link set a flag, like setting "is active" from TRUE to FALSE, or alternately, an "is deleted" flag from FALSE to TRUE.  After the task is submitted, the altered row is written to the DB and your future processing can account for deactivated and/or "soft deleted" rows.

Hi Naresh,

Thanks for your response. I have used a!deleteFromDataStoreEntities in interface

link: a!dynamicLink(
            value: ri!clickedRow,
            saveInto: {
              a!save(
                ri!data,
                remove(
                  ri!data,
                  ri!index
                )
              ),
			  a!deleteFromDataStoreEntities(
                  dataToDelete: {
                    entity: cons!CDT_Name, identifiers: ri!data[ri!index].Id
                  }
                )
            }
          )

But still it is not deleting from database. Could anyone please help me on this

It is very difficult to understand what you are trying here. In your code your are using ri!index, what is this ri!index? how u get this value? are you trying to delete inside grid? or this deletion logic is outside of grid?
