• What is the cause and solution for SAP error message WZ253 - Metadata of table/structure &1 cannot be read ?

  The SAP error message:
  WZ253 Metadata of table/structure &1 cannot be read
  typically occurs when the system is unable to access or retrieve the metadata (definition) of a specified table or structure. This metadata includes information such as field names, data types, lengths, and other attributes necessary for processing the table or structure.
  
  Cause
  
  Missing or Inactive Table/Structure: The table or structure name provided (&1) does not exist in the Data Dictionary (DDIC) or is inactive.
  Authorization Issues: The user or process does not have sufficient authorization to read the metadata of the specified object.
  Transport or Repository Issues: The table/structure might be corrupted or incompletely transported between systems.
  Incorrect Name or Typo: The name of the table or structure passed to the function/module is incorrect or misspelled.
  System Buffer or Cache Problem: The DDIC buffer might be outdated or corrupted, causing metadata retrieval to fail.
  Inconsistent or Missing DDIC Objects: The DDIC object might be inconsistent or missing due to incomplete activation or system inconsistencies.
  
  
  Solution
  
  
  Check Table/Structure Existence and Activation:
  
  Use transaction SE11 to check if the table or structure (&1) exists.
  If it exists but is inactive, activate it.
  If it does not exist, verify the source of the name and correct it.
  
  
  
  Verify Authorizations:
  
  Ensure the user or background job has the necessary authorizations to read DDIC objects.
  Check roles and profiles assigned to the user.
  
  
  
  Check for Typographical Errors:
  
  Verify the exact name of the table/structure passed to the program or function module.
  Correct any spelling mistakes.
  
  
  
  Re-Import or Re-Transport:
  
  If the object is corrupted or missing due to transport issues, re-import or re-transport the relevant package or object.
  
  
  
  Clear DDIC Buffer:
  
  Use transaction SE14 (Database Utility) or SE38 to run report RSINACTIV or RSDBBUFF to refresh or clear the DDIC buffer.
  Alternatively, perform a system buffer refresh using transaction SM56 or SMLG.
  
  
  
  Check System Logs and Dumps:
  
  Use ST22 to check for any short dumps related to this error.
