Function ID Main Package

The Main Package contains the basic validations and backend logic for the Maintenance function id. The Main package contains the mandatory checks required. It will also contain function calls to the other packages generated by RAD.

The main package has the below stages:
  • Converting Ts to PL/SQL Composite Type
  • Checking for mandatory fields
  • Defaulting and validating the data
  • Writing into Database
  • Querying the Data from database
  • Converting the Modified Composite Type again to TS

Each of these stages has a ‘Pre’ and ‘Post’ hooks in the Kernel, Cluster and Custom Packages. These Hooks are called from the Main Package itself. Main Package has the system-generated code and should not be modified by the developer Kernel, Cluster and Custom Packages are the packages where the respective team can add business logic in appropriate functions using the Pre and Post hooks available.
