write to multiple data store entity issue.

As far as I understand you should change the type of the process variable as you are storing data through an entity and using record type as the process variable type.
If you don't want to change your variable type then you can use write records smart service for storing data in the database.

The public Appian documentation explains clearly how to configure that node. docs.appian.com/.../Write_to_Multiple_Data_Store_Entities_Smart_Service.html

Hi Sunil,

Then it should give same error while using writeToDataStoreEnity also right, why it is not giving then?

Hi Stefan,

Thank for your comment in this discussion,
I know how to configure the things in this smart service, It is giving me an error while using WriteToMultipleDataStoreEntity not to the WriteToDataStoreEntity. Even though I casted from dictionary  to CDT, It is giving same error castInvalid to the WriteToMultipleDataStoreEntity not to the WriteToDataStoreEntity.

If there is any data type mismatch then why it is not giving an error while using WriteToDataStoreEntity.?

Because you try to feed a list of dictionaries into the a!entityData function. That does not work. You need to treat each item individually.

can you share the code?

/* BAD */
alentityData(
  {entity: cons!PEG_CMP_APPROVALHISTORY_DSE, data: pv!approvalHistory },
  {entity:cons!PEG_CMP_REQUEST_DSE, data: pv!request }
)

/* GOOD */
{
  a!entityData(entity: cons!PEG_CMP_APPROVALHISTORY_DSE, data: pv!approvalHistory),
  a!entityData(entity: cons!PEG_CMP_REQUEST_DSE, data: pv!request)
}
