Specifically, the message "Invalid input; input keys are initial" suggests that the keys or identifiers required for the operation are not being provided or are empty (initial).

  Missing Input Parameters: The most common cause is that the required input keys (such as IDs, codes, or other identifiers) are not being populated before the API call is made.
  Incorrect Data Mapping: If the data being passed to the API is not correctly mapped or formatted, it may result in initial values being sent.
  Logical Errors in Code: There may be logical errors in the code that lead to the input parameters not being set correctly.

  Solution:
  
  Check Input Parameters: Review the code or configuration where the API is being called. Ensure that all required input keys are being populated correctly.
  Debugging: Use debugging tools to trace the execution of the code and check the values of the input parameters just before the API call.
  Validation: Implement validation checks to ensure that the input parameters are not empty before making the API call. This can help catch issues early.
  User Training: If the input is user-generated, ensure that users are trained on what information is required and how to provide it correctly.
  Review Documentation: Check the API documentation to confirm the required input parameters and their expected formats.
  
  Related Information:
  
  SAP Notes: Look for SAP Notes related to the specific API or function module you are using. There may be known issues or patches available.

  Testing: If possible, create test cases with valid input to ensure that the API works as expected when provided with the correct data.
