• What is the cause and solution for SAP error message MDG_MDF107 - DDIC structures are being regenerated ?

  The SAP error message MDG_MDF107 indicates that there is an issue related to the regeneration of Data Dictionary (DDIC) structures in the context of Master Data Governance (MDG). This error typically arises when there are inconsistencies or issues with the underlying data structures that MDG relies on.
  Cause:
  
  Changes in Data Model: If there have been recent changes to the data model or the underlying structures, it may trigger the regeneration process.
  Inconsistencies: There may be inconsistencies in the data dictionary objects, such as missing or corrupted entries.
  Transport Issues: If there were recent transports that did not complete successfully, it could lead to issues with the DDIC structures.
  Custom Enhancements: Custom developments or enhancements that affect the MDG data model can also lead to this error.

  Regenerate DDIC Structures: 
  
  You can manually trigger the regeneration of the DDIC structures. This can typically be done through transaction codes like SE11 (Data Dictionary) or MDGIMG (MDG Implementation Guide).
  In the MDG context, you may need to execute the relevant activation or regeneration programs.
