• What is the cause and solution for SAP error message GHO_BO068 - Change not allowed; neighbouring link (&1) has the same attributes ?

  The SAP error message GHO_BO068, which states "Change not allowed; neighbouring link (&1) has the same attributes," typically occurs in the context of Business Object (BO) modeling or when working with graphical representations of data models in SAP systems, such as SAP BusinessObjects or SAP BW.
  Cause:
  This error arises when you attempt to change a link or relationship between objects in a data model, but the system detects that a neighboring link already exists with the same attributes. This is a safeguard to prevent redundancy and maintain the integrity of the data model. The attributes in question could include properties like cardinality, type, or other defining characteristics of the link.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Identify the Neighboring Link: Check the link mentioned in the error message (indicated by &1). Understand its attributes and how they compare to the link you are trying to change.
  
  
  Review Link Attributes: Compare the attributes of the existing neighboring link with the attributes of the link you are trying to create or modify. Ensure that they are not identical.
  
  
  Modify Your Change: If the neighboring link has the same attributes, you will need to either:
  
  Change the attributes of the link you are trying to create or modify so that they differ from the neighboring link.
  Remove or modify the existing neighboring link if it is not needed, but ensure that this does not disrupt the overall data model.
  
  
  
  Consult Documentation: If you are unsure about the attributes or the implications of changing links, refer to the SAP documentation or guidelines for the specific module you are working with.
  
  
  Testing: After making the necessary changes, test the data model to ensure that it functions as expected without any errors.
