• What is the cause and solution for SAP error message MDC_ADAPTER053 - &1 references not yet resolved, activation process restarted ?

  The SAP error message MDC_ADAPTER053 indicates that there are unresolved references in the context of the Multi-Dimensional Data Model (MDC) in SAP. This typically occurs during the activation process of a model or a data object, where the system encounters references that it cannot resolve, leading to the activation process being restarted.
  Cause:
  
  Unresolved References: The most common cause is that there are references to objects (like InfoObjects, DataSources, or other models) that are either missing, incorrectly defined, or not activated.
  Model Dependencies: If the model you are trying to activate has dependencies on other models or objects that are not yet activated or are in an inconsistent state, this can lead to unresolved references.
  Transport Issues: If the model or its dependencies were transported from another system and not all objects were transported correctly, this can lead to unresolved references.
  Data Model Changes: Changes made to the data model that have not been properly activated or saved can also lead to this error.
  
  Solution:
  
  Check Dependencies: Review the dependencies of the model you are trying to activate. Ensure that all referenced objects are activated and in a consistent state.
  Activate Dependencies: If you find any dependencies that are not activated, activate them first before attempting to activate the main model again.
  Review Object Definitions: Check the definitions of the objects that are referenced. Ensure that they are correctly defined and do not have any errors.
  Transport Consistency: If the issue arose after a transport, ensure that all related objects were transported correctly. You may need to re-transport missing objects.
  Check Activation Logs: Look at the activation logs for more detailed information about which references are unresolved. This can provide clues on what needs to be fixed.
  Recreate Objects: In some cases, if an object is corrupted or has issues, it may be necessary to recreate it.
  Consult Documentation: Refer to SAP documentation or notes related to the specific version you are using, as there may be known issues or patches available.
