• What is the cause and solution for SAP error message FDT_HRF155 - Input parameter &1; data element assignment is missing ?

  The SAP error message FDT_HRF155 indicates that there is a missing data element assignment for an input parameter in a specific context, typically related to the Field Data Tool (FDT) or the configuration of a form or interface in SAP. This error often arises when the system expects a certain data element to be assigned to an input parameter, but it is not found.
  Cause:
  
  Missing Data Element Assignment: The most common cause is that the input parameter defined in the FDT does not have a corresponding data element assigned to it.
  Configuration Issues: There may be issues in the configuration of the FDT or the related application where the input parameters are defined.
  Transport Issues: If the configuration was transported from one system to another (e.g., from development to production), the data element might not have been included in the transport.
  Changes in Data Model: Changes in the underlying data model or structure may lead to mismatches between expected and actual data elements.
  
  Solution:
  
  
  Check Input Parameter Configuration:
  
  Go to the FDT configuration where the input parameter is defined.
  Verify that the input parameter has a valid data element assigned to it. If not, assign the appropriate data element.
  
  
  
  Review Data Element Availability:
  
  Ensure that the data element you are trying to assign exists in the system. You can check this in the Data Dictionary (transaction SE11).
  If the data element is missing, you may need to create it or transport it from another system.
  
  
  
  Transport Check:
  
  If the issue arose after a transport, check the transport logs to ensure that all necessary objects were included in the transport request.
  
  
  
  Testing:
  
  After making the necessary changes, test the configuration to ensure that the error no longer occurs.
  
  
  
  Consult Documentation:
  
  Review any relevant SAP documentation or notes related to the FDT and the specific input parameters you are working with.
  
  
  
  Seek Help from SAP Support:
