• What is the cause and solution for SAP error message CACS_RTTS008 - Remote structure &1 from remote system &2 contains errors ?

  The SAP error message CACS_RTTS008 indicates that there is an issue with a remote structure from a remote system. This error typically occurs in the context of SAP systems that are integrated with other systems, such as when using Remote Function Calls (RFC) or when accessing data from a different SAP system or a non-SAP system.
  Cause:
  The error can be caused by several factors, including:
  
  
  Inconsistent Data Structure: The structure definition in the remote system does not match the expected structure in the local system. This can happen if there have been changes to the structure in the remote system that have not been reflected in the local system.
  
  
  Network Issues: Temporary network issues or connectivity problems between the systems can lead to incomplete or corrupted data being received.
  
  
  Authorization Issues: The user or system may not have the necessary permissions to access the remote structure, leading to errors when trying to retrieve or manipulate the data.
  
  
  Data Type Mismatches: There may be discrepancies in data types or lengths between the local and remote systems, causing the data to be interpreted incorrectly.
  
  
  Version Mismatch: If the remote system has been upgraded or changed, and the local system has not been updated accordingly, this can lead to compatibility issues.
  
  
  Solution:
  To resolve the CACS_RTTS008 error, you can take the following steps:
  
  
  Check Structure Definitions: Verify that the structure definitions in both the local and remote systems are consistent. You may need to compare the data dictionary (SE11) entries in both systems.
  
  
  Update Remote Function Module: If there have been changes in the remote system, ensure that the corresponding function modules or RFCs in the local system are updated to reflect these changes.
  
  
  Test Connectivity: Check the network connection between the systems. You can use transaction SM59 to test the RFC connection and ensure that it is functioning correctly.
  
  
  Review Authorizations: Ensure that the user or system has the necessary authorizations to access the remote structure. You can check this in transaction SU53 after the error occurs.
  
  
  Check for Data Type Issues: Review the data types and lengths of the fields in the structures to ensure they match between the systems.
  
  
  Consult SAP Notes: Look for any relevant SAP Notes that may address this specific error or provide guidance on similar issues.
  
  
  Debugging: If the issue persists, consider debugging the RFC call to identify where the error is occurring and gather more detailed information about the problem.
