• What is the cause and solution for SAP error message SADL_CONSUMP_SERVICE101 - Transactional entity has no primary key ?

  The SAP error message SADL_CONSUMP_SERVICE101 indicates that a transactional entity in your SAP system does not have a primary key defined. This is a common issue when working with the SAP ABAP programming model, particularly when using the SAP Data Layer (SADL) for service consumption.
  Cause:
  The error occurs because the transactional entity you are trying to access or manipulate does not have a unique identifier (primary key) defined. In SAP, every entity should have a primary key to uniquely identify each record. Without a primary key, the system cannot perform operations such as create, read, update, or delete (CRUD) on the entity.
  Solution:
  To resolve this issue, you need to ensure that the transactional entity has a primary key defined. Here are the steps you can take:
  
  
  Check the Entity Definition:
  
  Go to the definition of the transactional entity in the ABAP Dictionary (SE11).
  Verify that the entity has a primary key defined. If it does not, you will need to add one.
  
  
  
  Define a Primary Key:
  
  If the entity is missing a primary key, you can define one by selecting the appropriate fields that can uniquely identify each record.
  Ensure that the fields you choose as the primary key are not nullable and have unique values.
  
  
  
  Adjust the Service Definition:
  
  If you are using a service definition (e.g., OData service), ensure that the service is correctly configured to recognize the primary key of the entity.
  Regenerate the service if necessary to reflect the changes made to the entity definition.
  
  
  
  Test the Changes:
  
  After making the necessary changes, test the service or transaction again to ensure that the error is resolved.
