• What is the cause and solution for SAP error message /PM0/3FW_MESSAGES107 - Emod: &1; child entity &2 hast > 1 parent (model) ?

  The SAP error message /PM0/3FW_MESSAGES107 indicates that there is a problem with the hierarchical structure of entities in a model, specifically that a child entity is associated with more than one parent entity. This situation can lead to ambiguity in the data structure and is not allowed in the context of the model being used.
  Cause:
  The error typically arises in scenarios where:
  
  Data Model Configuration: The child entity (e.g., a project, task, or resource) is incorrectly configured to have multiple parent entities. This can happen due to incorrect data entry or configuration in the system.
  Data Import/Integration Issues: If data is being imported from external sources or integrated from other systems, it may lead to a situation where a child entity is linked to multiple parents.
  Model Design Flaw: The design of the data model may not adhere to the required hierarchical structure, leading to violations of the one-to-many relationship that is expected.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Identify the Entities: Check the specific child entity (&2) and its associated parent entities (&1). You can do this by reviewing the model configuration or using transaction codes that allow you to view entity relationships.
  
  
  Review Data Relationships: Analyze the relationships between the entities to determine why the child has multiple parents. This may involve checking the configuration settings or data entries in the relevant tables.
  
  
  Correct the Configuration: 
  
  If the child entity is incorrectly linked to multiple parents, you will need to modify the configuration to ensure that each child entity has only one parent.
  This may involve deleting or reassigning relationships in the model.
  
  
  
  Data Cleanup: If the issue is due to data import or integration, ensure that the data being imported adheres to the model's constraints. Clean up any duplicate relationships in the source data before importing.
  
  
  Testing: After making the necessary changes, test the model to ensure that the error no longer occurs and that the hierarchical structure is valid.
  
  
  Documentation and Training: Ensure that the team responsible for data entry or model configuration is aware of the correct structure and constraints to prevent similar issues in the future.
  
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for the specific module you are working with, as it may provide additional insights into the expected data model and relationships.
  SAP Community: Engage with the SAP Community forums to see if others have encountered similar issues and what solutions they have implemented.
  Transaction Codes: Familiarize yourself with relevant transaction codes that can help you analyze and manage entity relationships, such as SE11 (Data Dictionary) or SE80 (Object Navigator).
  
  By following these steps, you should be able to resolve the error and ensure that your data model adheres to the required structure.
