How To Fix UGMD115 - Field &1 cannot be a node in hierarchies of characteristic &2

SAP Error Message - Details

• Message type: E = Error

• Message class: UGMD - FIN Master Data: Messages

• Message number: 115

• Message text: Field &1 cannot be a node in hierarchies of characteristic &2

What causes this issue?

According to the data basis definition, &v1& should be used as a node
characteristic in hierarchies of characteristic &v2&. However, the
definition of data basis &v4& already shows that a different field (&v3&
) should be used as the node characteristic for &v2&. The assignment of
the node characteristic must be unique for the entire client.

• What is the cause and solution for SAP error message UGMD115 - Field &1 cannot be a node in hierarchies of characteristic &2 ?

  The SAP error message UGMD115 indicates that a specific field (denoted as &1) cannot be used as a node in the hierarchies of a characteristic (denoted as &2). This error typically arises in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence) when dealing with characteristics and their hierarchies.
  Cause:
  
  Invalid Field Usage: The field you are trying to use as a node in a hierarchy is not defined correctly or is not suitable for hierarchical representation.
  Data Type Mismatch: The data type of the field may not be compatible with the requirements for a hierarchy node.
  Hierarchy Configuration: The characteristic may not be configured to allow hierarchies, or the hierarchy itself may not be properly defined.
  Missing Master Data: The field may not have the necessary master data entries that would allow it to function as a node in a hierarchy.
  
  Solution:
  
  Check Field Definition: Ensure that the field you are trying to use as a node is defined correctly in the data model. Verify that it is intended to be used in a hierarchy.
  Review Characteristic Settings: Go to the characteristic settings in the SAP BW/BI system and check if hierarchies are enabled for that characteristic.
  Data Type Verification: Ensure that the data type of the field is compatible with the hierarchy requirements. For example, it should typically be a character or numeric type that can represent a hierarchy.
  Master Data Check: Verify that the necessary master data exists for the field. If the field is supposed to represent nodes in a hierarchy, ensure that there are entries that can serve as parent and child nodes.
  Hierarchy Structure: If you are creating or modifying a hierarchy, ensure that the structure is correctly defined, with appropriate parent-child relationships.
  Rebuild Hierarchy: If the hierarchy is corrupted or not functioning as expected, consider rebuilding it from scratch.
  
  Related Information:
  
  SAP Notes: Check SAP Notes related to this error message for any specific patches or updates that may address the issue.
  Documentation: Refer to SAP documentation on characteristics and hierarchies in BW/BI for detailed guidelines on how to set them up correctly.
  Transaction Codes: Use transaction codes like RSA1 (Data Warehousing Workbench) to access the relevant settings and configurations for characteristics and hierarchies.
  Community Forums: Engage with SAP community forums or support channels for additional insights and solutions from other users who may have encountered similar issues.
  
  By following these steps, you should be able to identify the root cause of the UGMD115 error and implement the necessary corrections to resolve it.
