• What is the cause and solution for SAP error message DD_MT_SHARING_CHK028 - & usages in Dynamic Cached Views found ?

  The SAP error message DD_MT_SHARING_CHK028 typically relates to issues with dynamic cached views in the context of data dictionary objects. This error indicates that there is a problem with the sharing of data elements or structures in the context of dynamic caching, which can occur when multiple views or objects are trying to access the same data structure in a way that is not allowed.
  Cause:
  
  Data Structure Conflicts: The error often arises when there are conflicting definitions or usages of data elements or structures in different views or programs.
  Dynamic Caching Issues: Dynamic cached views are designed to improve performance by caching data. If there are inconsistencies in how these views are defined or used, it can lead to this error.
  Inconsistent Data Types: If the data types or structures used in the views are not compatible, it can trigger this error.
  Transport Issues: Sometimes, changes made in the development environment may not have been properly transported to the production environment, leading to inconsistencies.
  
  Solution:
  
  Check Data Definitions: Review the data elements and structures used in the views to ensure that they are consistent and correctly defined.
  Review Dynamic Caching Settings: Ensure that the settings for dynamic caching are correctly configured and that there are no conflicts in the caching strategy.
  Consistency Check: Perform a consistency check on the data dictionary objects involved. This can often be done using transaction codes like SE11 or SE14.
  Transport Management: If the issue is related to transport, ensure that all relevant objects have been transported correctly and that there are no missing dependencies.
  Debugging: If the error persists, consider debugging the program or view to identify the exact point of failure and the data structures involved.
  
  Related Information:
  
  Dynamic Cached Views: These are views that cache data dynamically to improve performance. They are often used in scenarios where data is frequently accessed but does not change often.
  Data Dictionary (DDIC): The SAP Data Dictionary is a central repository that contains definitions of all data elements, structures, tables, and views in the SAP system.
  Transaction Codes: Familiarize yourself with transaction codes like SE11 (Data Dictionary), SE14 (Database Utility), and SE80 (Object Navigator) for managing and troubleshooting data dictionary objects.
  
  Usage in Dynamic Cached Views:
  Dynamic cached views are commonly used in scenarios where performance is critical, such as in reporting or data retrieval processes. However, they require careful management of data structures to avoid conflicts and ensure that the data remains consistent and reliable.
