• What is the cause and solution for SAP error message FDT_CP_MSG457 - Line Type used in Data Object : &1 is not structure ?

  The SAP error message FDT_CP_MSG457 indicates that there is an issue with the line type used in a data object within the context of the SAP Field Data Tool (FDT). Specifically, the error states that the line type specified is not a structure, which is a requirement for the operation you are trying to perform.
  Cause:
  
  Incorrect Line Type: The line type defined in the data object is not a structure type. In SAP, a structure is a composite data type that can contain multiple fields, while a line type may refer to a simple data type or a different kind of data object.
  Configuration Error: There may be a misconfiguration in the data object settings where the expected structure is not properly defined or linked.
  Data Object Definition: The data object may have been defined incorrectly, leading to the system not recognizing it as a structure.
  
  Solution:
  
  
  Check Data Object Definition:
  
  Go to the relevant transaction in SAP where the data object is defined.
  Verify that the line type is indeed a structure. You can do this by checking the data dictionary (SE11) for the line type definition.
  
  
  
  Modify Line Type:
  
  If the line type is not a structure, you will need to either change it to a valid structure or create a new structure that meets the requirements of your data object.
  Ensure that the structure contains the necessary fields and is properly defined.
  
  
  
  Review Configuration:
  
  Check the configuration settings related to the data object and ensure that all references to line types and structures are correct.
  If you are using a custom development, review the code to ensure that the correct data types are being used.
  
  
  
  Testing:
  
  After making the necessary changes, test the data object again to ensure that the error is resolved.

  SAP Community: Engage with the SAP Community forums to see if others have encountered similar issues and what solutions they have found.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SE11 (Data Dictionary), SE80 (Object Navigator), and FDT-related transactions for troubleshooting.
