• Message class: SADL_GW_DT_CDS - Messages CDS Checks

• Message number: 000

• Message text: CDS Modeling Check (SADL/BOPF)

What causes this issue?

This ATC check evaluates annotations and CDS modelling to prevent
unexpected runtime issues
Examples:
- Transactional consumption views
(@ObjectModel.transactionalProcessingDelegated) have to use
transactional views as source (Annotation:
@ObjectModel.transactionalProcessingEnabled)
- Use the annotation @ObjectModel.draftEnabled only for transactional
consumption views or transactional views. All other views will cause
problems during the SADL runtime.
- Joins are not allowed in transactional consumption views.
- The root view of a composition must contain the annotation
@ObjectModel.compostionRoot.
- Transient fields in transactional consumption views must be read-only.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

SADL_GW_DT_CDS000 - Details

• The SAP error message SADL_GW_DT_CDS000 typically relates to issues encountered during the modeling of Core Data Services (CDS) views, particularly when using the SADL (Service Adaptation Definition Language) framework or BOPF (Business Object Processing Framework). This error can arise due to various reasons, including incorrect annotations, data type mismatches, or issues with the underlying data model.
  Causes:
  
  Incorrect Annotations: The CDS view may have incorrect or missing annotations that are required for proper integration with SADL or BOPF.
  Data Type Mismatches: There may be inconsistencies in data types between the CDS view and the underlying database tables or other CDS views.
  Missing or Incorrect Associations: If the CDS view relies on associations that are not correctly defined, it can lead to this error.
  Incompatible Data Model: The data model used in the CDS view may not be compatible with the expectations of the SADL framework.
  Semantic Errors: Logical errors in the CDS view definition can also
