• What is the cause and solution for SAP error message BS_SOA_COMMON021 - No input data provided, error while calling API for &1. ?

  The SAP error message BS_SOA_COMMON021 indicates that there was an issue with an API call due to the absence of input data. This error typically occurs in scenarios where a service or function module is expected to receive input parameters but does not receive any, leading to a failure in processing the request.
  Cause:
  
  Missing Input Data: The most common cause is that the API call was made without providing the necessary input parameters. This could be due to a programming error, a misconfiguration, or an oversight in the data preparation stage.
  Incorrect Mapping: If the input data is being mapped from another source (like a UI or another system), there may be an issue with the mapping logic that results in no data being sent.
  Data Validation: The input data might have been filtered out or rejected due to validation rules, leading to an empty payload being sent to the API.
  System Configuration: There may be configuration issues in the system that prevent the correct data from being retrieved or sent.
  
  Solution:
  
  Check Input Parameters: Review the API call to ensure that all required input parameters are being provided. Make sure that the data is being populated correctly before the API call is made.
  Debugging: Use debugging tools to trace the execution of the program or process that leads to the API call. This can help identify where the input data is being lost or not set.
  Review Mapping Logic: If the input data is coming from another source, check the mapping logic to ensure that data is being correctly transferred to the API call.
  Validation Rules: Review any validation rules that might be filtering out the input data. Ensure that the data being sent meets all necessary criteria.
  Consult Documentation: Refer to the API documentation to understand the required input parameters and their formats. Ensure that the data being sent adheres to these specifications.
