Hi Dhaval,
You should not hardcode the physical table name and column name, it can be different depending on the environment where your application is deployed and run.
You can retrieve it with the following query:
SELECT PHYSICAL_TABLE_NAME FROM OSSYS_ENTITY WHERE NAME = <NameForOutsystemsEntityInServiceStudio>.
Then save the output of this query in a local text parameter, which you then pass to the BulkInsert action.
Find the actual column name using a query on JOIN of OSSYS_ENTITY and OSSSY_ENTITY_ATTR with WHERE clause by service studio name of entity and service studio name of the entity attribute.
Regards,
Daniel
