• What is the cause and solution for SAP error message /PM0/ABP_BTX219 - Key mapping can always only process a single mapping for each call ?

  The SAP error message /PM0/ABP_BTX219 Key mapping can always only process a single mapping for each call typically occurs in the context of SAP Business Technology Platform (BTP) or when dealing with data mapping in SAP applications. This error indicates that the key mapping process is attempting to handle multiple mappings in a single call, which is not supported.
  Cause:
  
  Multiple Mappings in a Single Call: The primary cause of this error is that the system is trying to process more than one key mapping at the same time. The key mapping function is designed to handle only one mapping per execution.
  Incorrect Configuration: There may be a misconfiguration in the mapping settings or the way the data is being sent to the mapping function.
  Data Structure Issues: The data structure being passed to the mapping function may not conform to the expected format, leading to the system attempting to process multiple mappings.
  
  Solution:
  
  Single Mapping Call: Ensure that your implementation or configuration is set up to call the key mapping function with only one mapping at a time. Review the code or configuration that triggers the mapping process.
  Check Configuration: Review the configuration settings for the key mapping to ensure that it is set up correctly. This includes checking any relevant parameters or settings that dictate how mappings are processed.
  Debugging: If you have access to debugging tools, trace the execution of the mapping function to identify where multiple mappings are being triggered. This can help pinpoint the source of the issue.
  Review Data Input: Ensure that the data being passed to the mapping function is structured correctly and does not inadvertently contain multiple mappings.
