• What is the cause and solution for SAP error message /ISDFPS/SYNC199 - Force switch set - Start of ALE inb. procg also without ready indicator ?

  The SAP error message /ISDFPS/SYNC199 typically relates to issues in the Advanced Business Application Programming (ABAP) environment, particularly in the context of Application Link Enabling (ALE) processing. This error indicates that there is a problem with the synchronization of data between systems, often due to the force switch being set incorrectly or the absence of a ready indicator for inbound processing.
  Cause:
  
  Force Switch Set: The error suggests that the force switch for ALE processing is activated, which can lead to issues if the system is not ready to process inbound messages.
  Ready Indicator: The absence of a ready indicator means that the system is not prepared to handle incoming messages, which can cause synchronization problems.
  Configuration Issues: There may be misconfigurations in the ALE settings or in the distribution model.
  Network Issues: Problems with the network or communication between systems can also lead to this error.
  
  Solution:
  
  Check Configuration: Review the ALE configuration settings in the SAP system. Ensure that the distribution model is correctly set up and that all necessary settings are in place.
  Force Switch: If the force switch is not needed, consider disabling it. This can usually be done in the transaction code SIMG or SPRO under the relevant ALE settings.
  Ready Indicator: Ensure that the system is in a state where it can process inbound messages. This may involve checking the status of the relevant application or service.
  Monitor Background Jobs: Check if there are any background jobs that might be affecting the processing of inbound messages. Ensure that they are running correctly.
  Check Logs: Review the application logs (transaction SLG1) for any additional error messages or warnings that could provide more context about the issue.
  Test Communication: If the issue is related to communication between systems, test the connection using transaction SM59 to ensure that the RFC connections are functioning properly.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as ALEAUDIT, BD87, and SM58 for monitoring and troubleshooting ALE issues.
  SAP Notes: Check for any SAP Notes related to this error message. SAP frequently releases notes that address specific issues and provide guidance on resolution.
  Documentation: Review SAP documentation on ALE and IDoc processing for best practices and troubleshooting steps.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP Basis or technical team for further investigation, as they may have access to more detailed logs and system settings.
