• What is the cause and solution for SAP error message /ISIDEX/EDEREG_INV029 - Missing allocation of internal ID to external ID ?

  The SAP error message /ISIDEX/EDEREG_INV029 Missing allocation of internal ID to external ID typically occurs in the context of the SAP IS-IS (Industry Solution for Utilities) module, particularly when dealing with the integration of internal and external identifiers for business objects, such as customers, contracts, or other entities.
  Cause:
  This error indicates that there is a missing mapping or allocation between an internal ID (used within the SAP system) and an external ID (used in external systems or interfaces). This can happen due to several reasons, including:
  
  Data Migration Issues: During data migration from legacy systems to SAP, the mapping between internal and external IDs may not have been established correctly.
  Configuration Errors: The configuration settings for the ID mapping may not be set up properly in the system.
  Missing Master Data: The required master data that links the internal and external IDs may be missing or incomplete.
  Integration Issues: If there are integrations with external systems (like CRM or third-party applications), the necessary mappings may not have been created or synchronized.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Configuration: Verify the configuration settings for ID mapping in the relevant customizing settings. Ensure that the mapping between internal and external IDs is correctly defined.
  
  
  Review Master Data: Check the master data records to ensure that the internal and external IDs are correctly maintained. If any records are missing, you may need to create or update them.
  
  
  Data Migration Review: If this issue arose after a data migration, review the migration process to ensure that all necessary mappings were created. You may need to re-run the migration or manually create the mappings.
  
  
  Use Transaction Codes: Utilize relevant transaction codes (like SE11 for data dictionary, SE16 for table display) to check the tables that store the mappings. Look for tables like /ISIDEX/IDMAP or similar, depending on your specific implementation.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to the specific version of IS-IS you are using. There may be specific notes or patches that address this issue.
  
  
  Contact SAP Support: If the issue persists after checking the above points, consider reaching out to SAP support for further assistance. They may provide insights or patches that are specific to your version or configuration.
