• What is the cause and solution for SAP error message ESH_ENG_CDS_ABAP076 - Activation running in parallel; this one is cancelled ?

  The SAP error message ESH_ENG_CDS_ABAP076 indicates that an activation process for a Core Data Services (CDS) view is being canceled because it is running in parallel with another activation process. This typically occurs in environments where multiple users or processes are trying to activate the same CDS view or related objects simultaneously.
  Cause:
  
  Concurrent Activations: The most common cause is that multiple sessions or users are trying to activate the same CDS view or related objects at the same time.
  Long-running Processes: If one activation process is taking too long, it may lead to timeouts or cancellations of other concurrent activation attempts.
  Locking Mechanisms: SAP uses locking mechanisms to prevent data inconsistencies. If one process holds a lock on the object, other processes trying to activate it will be canceled.
  
  Solution:
  
  Check for Active Sessions: Use transaction SM50 or SM66 to check for active processes. Look for any long-running activation processes that might be blocking others.
  Wait and Retry: If you find that another activation is in progress, wait for it to complete and then retry the activation.
  Avoid Concurrent Activations: Ensure that only one user or process is activating the CDS view at a time. Coordinate with your team to avoid simultaneous activations.
  Check for Locks: Use transaction SM12 to check for any locks on the CDS view or related objects. If you find any unnecessary locks, you may need to delete them (ensure you understand the implications of doing so).
  Review System Performance: If activations are frequently taking too long, consider reviewing system performance and optimizing the underlying database or application server.
  Transport Requests: If the CDS view is part of a transport request, ensure that the transport is not being activated in multiple systems simultaneously.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with transaction codes like SE11 (Data Dictionary), SE80 (Object Navigator), SE37 (Function Builder), and SE38 (ABAP Editor) for managing and activating CDS views.
  SAP Notes: Check for any relevant SAP Notes that might address known issues or provide patches related to this error.
  Documentation: Review SAP documentation on Core Data Services and activation processes for best practices and troubleshooting tips.
