• What is the cause and solution for SAP error message /BOFU/FDT_EXP_BO_RET178 - Line type &1 of result data object table &2 must be a structure ?

  The SAP error message /BOFU/FDT_EXP_BO_RET178 indicates that there is an issue with the data structure being used in a Business Object (BO) within the SAP system. Specifically, the error states that the line type of the result data object table must be a structure, but it is not.
  Cause:
  This error typically arises due to one of the following reasons:
  
  
  Incorrect Data Type: The line type defined for the result data object is not a structure. In SAP, a structure is a composite data type that can contain multiple fields, while a table type can be a simple array or a different data type.
  
  
  Configuration Issues: There may be a misconfiguration in the Business Object or the data model that defines how data is structured and returned.
  
  
  Data Model Changes: If there have been recent changes to the data model or the underlying structures, it may lead to inconsistencies that trigger this error.
  
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Data Object Definition:
  
  Go to the definition of the result data object table (in the relevant transaction or development environment).
  Ensure that the line type is defined as a structure. If it is not, you will need to change it to a structure type.
  
  
  
  Review Business Object Configuration:
  
  Verify the configuration of the Business Object to ensure that it is correctly set up to return data in the expected format.
  If necessary, adjust the configuration to align with the expected data structure.
  
  
  
  Test Changes:
  
  After making the necessary changes, test the Business Object to ensure that the error no longer occurs and that the data is returned correctly.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for specific guidance on defining structures and data objects within the context of your SAP version and modules.
  
  
  
  Seek Help from SAP Support:
  
  If the issue persists after checking the above points, consider reaching out to SAP support for further assistance. They may provide insights specific to your system configuration.
