  The SAP error message AD721 indicates that there was a failure in the nametab generation for a table due to issues related to the client field. This error typically arises during the activation of a table or when changes are made to a table structure that involves the client field.
  Cause:
  
  
  Client Field Issues: The error often occurs when there are problems with the client field (usually the field MANDT) in the table definition. This could be due to:
  
  The client field not being defined correctly.
  The client field being marked as non-client-specific in a way that conflicts with the table's intended use.
  Inconsistencies in the table definition or its relationship with other tables.
  
  
  
  Table Definition Problems: There may be issues with the table definition itself, such as:
  
  Missing or incorrect data elements.
  Incorrect field attributes.
  Problems with the primary key definition.
  
  
  
  Transport Issues: If the table was transported from another system, there might be inconsistencies or missing components in the transport request.
  
  
  Solution:
  
  
  Check Table Definition:
  
  Go to the Data Dictionary (SE11) and check the definition of the table that is causing the error.

  Check for Dependencies:
