• What is the cause and solution for SAP error message WE028 - Table & not in DDIC ?

  The SAP error message WE028: Table & not in DDIC typically occurs in the context of IDoc processing or ALE/EDI scenarios.
  
  Meaning of the Error
  
  Message: Table & not in DDIC  
  Explanation: The system is trying to access or reference a table (the name of which replaces the & placeholder) that does not exist in the Data Dictionary (DDIC).
  
  
  Cause
  
  The IDoc processing or ALE configuration references a table that is not defined in the SAP Data Dictionary.
  This can happen if:
  
  A custom or standard IDoc segment or message type is linked to a table that has been deleted or not created.
  The system is trying to access a table that is misspelled or incorrectly specified in the configuration.
  The relevant table is part of a custom development and has not been transported or activated properly.
  The IDoc or ALE configuration is inconsistent or incomplete.
  
  
  
  
  Where it Occurs
  
  During IDoc inbound or outbound processing.
  When generating or processing IDoc segments.
  In ALE distribution model or partner profile configuration.
  When using function modules or programs that expect certain tables to exist.
  
  
  How to Identify the Table Name
  
  The actual table name is shown in the error message replacing the &.
  Check the short dump or system log (transaction ST22 or SM21) for more details.
  Check the IDoc segment or message type configuration to see which tables are referenced.
  
  
  Solution
  
  
  Verify Table Existence:
  
  Use transaction SE11 to check if the table exists in the Data Dictionary.
  If the table does not exist, determine if it should be created or if the reference is incorrect.
  
  
  
  Check Configuration:
  
  Review the IDoc segment and message type definitions in transactions WE30 (IDoc type development) and WE31 (segment editor).
  Check the distribution model (BD64) and partner profiles (WE20) for any incorrect table references.
  
  
  
  Correct the Reference:
  
  If the table name is misspelled, correct it in the configuration.
  If a custom table is missing, create it or transport it from the development system.
  
  
  
  Transport and Activate:
  
  Ensure that any custom tables or DDIC objects are properly activated and transported to the target system.
  
  
  
  Check Custom Code:
  
  If custom function modules or programs are involved, verify that they reference existing tables.
  
  
  
  Reprocess the IDoc:
  
  After fixing the issue, reprocess the IDoc or restart the ALE/EDI process.
  
  
  
  
  Additional Notes
  
  This error is a sign of inconsistency between the IDoc/ALE configuration and the system's Data Dictionary.
  Always perform changes in a development or sandbox system first.
  If unsure about the table, consult the SAP standard documentation or OSS notes related to the specific IDoc type or message.
