• What is the cause and solution for SAP error message MPE_AHF_CUST008 - Only 1 base object with seq. 1 allowed for object type &1 ?

  The SAP error message MPE_AHF_CUST008 indicates that there is an issue with the configuration of base objects in the system. Specifically, it states that only one base object with sequence number 1 is allowed for the specified object type. This error typically arises in the context of Advanced Hierarchy Framework (AHF) or similar configurations where base objects are defined.
  Cause:
  The error is caused by the following scenarios:
  
  Duplicate Base Objects: There are multiple base objects defined with the same sequence number (1) for the same object type. The system expects only one base object with that sequence number.
  Incorrect Configuration: The configuration settings for the object type may not be set up correctly, leading to conflicts in the hierarchy definitions.
  
  Solution:
  To resolve the error, you can follow these steps:
  
  
  Check Base Object Configuration:
  
  Navigate to the configuration settings for the object type in question.
  Look for the base objects defined for that object type and check their sequence numbers.
  
  
  
  Identify Duplicates:
  
  Identify if there are multiple entries with sequence number 1 for the same object type.
  If duplicates are found, you will need to either delete or modify the sequence number of the additional entries to ensure that only one base object has sequence number 1.
  
  
  
  Adjust Sequence Numbers:
  
  If you need to keep multiple base objects, adjust their sequence numbers so that they are unique. For example, change one of the duplicates to sequence number 2 or higher.
  
  
  
  Test the Configuration:
  
  After making the necessary changes, test the configuration to ensure that the error no longer occurs.
  
  
  
  Consult Documentation:
  
  If you are unsure about the configuration settings, refer to the SAP documentation or help resources related to the Advanced Hierarchy Framework or the specific module you are working with.
