• What is the cause and solution for SAP error message HP_LOAD018 - Edge Type must be entered for Hierarchy Loading defined on node type &1 ?

  The SAP error message HP_LOAD018 indicates that when attempting to load a hierarchy, the system requires an "Edge Type" to be specified for the hierarchy loading process defined on a particular node type. This error typically arises in the context of SAP applications that deal with hierarchical data structures, such as SAP HANA or SAP BW.
  Cause:
  The error occurs because:
  
  The hierarchy loading process is expecting an "Edge Type" to be defined for the specified node type, but it has not been provided.
  The configuration for the hierarchy loading might be incomplete or incorrectly set up.
  There may be a missing or incorrect entry in the hierarchy definition that does not specify how the nodes are connected (i.e., the relationships between parent and child nodes).
  
  Solution:
  To resolve the HP_LOAD018 error, you can take the following steps:
  
  
  Check Hierarchy Configuration:
  
  Go to the hierarchy definition in the SAP system and ensure that the "Edge Type" is defined for the node type mentioned in the error message.
  Make sure that the hierarchy structure is correctly set up, including all necessary relationships.
  
  
  
  Define Edge Type:
  
  If the Edge Type is not defined, you will need to create or specify it. This can usually be done in the hierarchy maintenance transaction (e.g., transaction code HIERARCHY or similar, depending on your SAP version).
  Ensure that the Edge Type corresponds to the relationships you want to establish between the nodes.
  
  
  
  Review Data Load Process:
  
  Check the data load process or the data source that is being used to load the hierarchy. Ensure that it includes the necessary fields for the Edge Type.
  If you are using a data extraction tool or ETL process, verify that it is configured to include the Edge Type in the data being loaded.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation or help resources for specific guidance on hierarchy loading and Edge Type definitions. This can provide insights into the required configurations and best practices.
  
  
  
  Testing:
  
  After making the necessary changes, test the hierarchy loading process again to ensure that the error is resolved.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes for hierarchy management, such as HIERARCHY, SE11 (Data Dictionary), or SE80 (Object Navigator).
  SAP Notes: Check SAP Notes for any known issues or patches related to hierarchy loading and the specific error message.
  Community Forums: Engage with SAP community forums or support channels for additional insights and troubleshooting tips from other users who may have encountered similar issues.
  
  By following these steps, you should be able to resolve the HP_LOAD018 error and successfully load your hierarchy in SAP.
