Smart SAP Assistant

• What is the cause and solution for SAP error message ESH_ENG_CDS_ABAP091 - CDS-entity & is already 'active' (@EnterpriseSearch.enabled: true) ?

  The SAP error message ESH_ENG_CDS_ABAP091 indicates that the Core Data Services (CDS) entity you are trying to activate is already in an active state. This error typically arises in the context of SAP Enterprise Search or when working with CDS views in ABAP.
  Cause:
  
  Already Active: The primary cause of this error is that the CDS entity you are trying to activate is already active in the system. This can happen if the activation process was attempted multiple times or if the entity was previously activated by another user or process.
  Transport Issues: If you are working in a transport environment, there might be inconsistencies between the transport requests and the active objects in the target system.
  System Caching: Sometimes, the system might have cached the state of the CDS entity, leading to confusion about its current status.
  
  Solution:
  
  Check Activation Status: Verify the activation status of the CDS entity in the ABAP Development Tools (ADT) or SE11 transaction. If it is already active, you do not need to activate it again.
  Recheck Dependencies: Ensure that all dependent objects of the CDS entity are also active. Sometimes, dependencies can cause issues even if the main entity is active.
  Clear Cache: If you suspect caching issues, you can try clearing the cache. You can do this by using transaction code /IWFND/CACHE to clear the cache for OData services or using transaction SE11 to refresh the CDS view.
  Transport Management: If you are in a transport environment, ensure that the transport requests are correctly imported and that there are no inconsistencies between the development and production systems.
  Check for Errors in Logs: Look into the system logs (transaction SLG1) for any related error messages that might provide more context about the issue.
