• What is the cause and solution for SAP error message SZDM_CC_CHKS_TITLES077 - Tables referencing this object become read only during a ZDO upgrade ?

  The SAP error message SZDM_CC_CHKS_TITLES077 indicates that during a Zero Downtime Upgrade (ZDO), certain tables that reference a specific object become read-only. This is a common scenario in SAP upgrades, especially when the system is transitioning to a new version while still allowing for ongoing operations.
  Cause:
  The primary cause of this error is related to the way SAP handles database changes during an upgrade. When a ZDO is performed, the system needs to ensure data consistency and integrity. As a result, certain tables that reference objects being modified or upgraded are locked to prevent any changes that could lead to inconsistencies. This is particularly important for tables that are involved in the upgrade process, as they may be in a transitional state.
  Solution:
  To resolve this issue, you can follow these steps:
  
  
  Check Upgrade Documentation: Review the specific upgrade documentation provided by SAP for your version. This documentation often contains information about known issues and how to handle them.
  
  
  Monitor Upgrade Process: Ensure that the upgrade process is being monitored correctly. Sometimes, the error may resolve itself as the upgrade progresses.
  
  
  Database Lock Management: If the tables are still in a read-only state after the upgrade process has completed, you may need to check for any lingering database locks. Use transaction codes like SM12 to view and manage locks.
  
  
  Post-Upgrade Activities: After the upgrade, perform any necessary post-upgrade activities as outlined in the upgrade guide. This may include running specific reports or programs to release locks or update statistics.
  
  
  SAP Notes: Search for relevant SAP Notes that may address this specific error. SAP frequently releases notes that provide fixes or workarounds for known issues encountered during upgrades.
  
  
  Consult SAP Support: If the issue persists and you cannot find a resolution, consider reaching out to SAP Support for assistance. They can provide guidance based on the specifics of your system and the upgrade process.
