• What is the cause and solution for SAP error message SRF_AUTHORING191 - Mandatory key field &1 missing for reported items table &2 ?

  The SAP error message SRF_AUTHORING191 indicates that a mandatory key field is missing for the reported items table in the context of SAP Fiori or SAP UI5 applications. This error typically arises during the development or configuration of applications that utilize the SAP Fiori elements framework, particularly when defining the data model or annotations.
  Cause:
  The error is caused by the absence of a required key field in the data model or the annotations that define the structure of the entity set. In SAP, key fields are essential for uniquely identifying records in a database table or entity. If a mandatory key field is not specified, the system cannot process the data correctly, leading to this error.
  Solution:
  To resolve the SRF_AUTHORING191 error, follow these steps:
  
  
  Identify the Missing Key Field:
  
  Review the error message to identify which key field (&1) is missing for the specified table (&2).
  Check the data model or the OData service definition to determine the expected key fields for the entity.
  
  
  
  Update the Data Model:
  
  If you are using an OData service, ensure that the service definition includes the required key fields. This can be done in the service metadata or in the underlying database table.
  If you are using annotations, make sure that the annotations for the entity set correctly define the key fields.
  
  
  
  Check Annotations:
  
  If you are using SAP Fiori elements, verify that the annotations in the CDS (Core Data Services) view or the annotation file are correctly defined. Ensure that the @Key annotation is present for the required fields.
  
  
  
  Regenerate the OData Service:
  
  If changes were made to the data model or annotations, regenerate the OData service to ensure that the changes are reflected.
  
  
  
  Test the Application:
