• What is the cause and solution for SAP error message FTI_TEMPLATE018 - Parameter &1 is not mapped to &2 fields in the LDB ?

  The SAP error message FTI_TEMPLATE018 indicates that there is a mapping issue between parameters in a function module or report and the fields in the Logical Database (LDB). Specifically, it means that a parameter (denoted as &1) is not correctly mapped to the expected fields (denoted as &2) in the LDB.
  Cause:
  
  Incorrect Mapping: The parameter specified in the function module or report is not correctly mapped to the fields defined in the Logical Database.
  Missing Fields: The fields that the parameter is supposed to map to may not exist in the LDB.
  Changes in LDB Structure: If the structure of the LDB has been changed (e.g., fields added or removed), the mapping may no longer be valid.
  Custom Development: If there are custom developments or modifications, they may not align with the standard LDB structure.
  
  Solution:
  
  Check Parameter Mapping: Review the parameters in your function module or report and ensure they are correctly mapped to the fields in the LDB.
  Verify LDB Structure: Check the structure of the Logical Database to confirm that the fields you are trying to map to actually exist.
  Adjust Code: If necessary, adjust the code in your function module or report to ensure that all parameters are correctly mapped to the corresponding fields in the LDB.
  Consult Documentation: Refer to SAP documentation or the data dictionary (SE11) to understand the expected mappings and structures.
  Debugging: Use debugging tools to trace the execution and identify where the mapping fails.
  
  Related Information:
  
  Transaction Codes: You can use transaction codes like SE11 (Data Dictionary) to view the structure of the LDB and SE37 (Function Module) to check the parameters of the function module.
  Logical Databases: Familiarize yourself with the concept of Logical Databases in SAP, as they are used to retrieve data in a structured way.
