What causes this issue?

For security reasons, you cannot use commands such as "/o<(>
<<)>transaction code>" or "/n<transaction code>" in the command field
when debugging in an RFC context.
You cannot make entries in the command field when debugging
transactional RFCs (tRFC, qRFC, bgRFC) either.

• What is the cause and solution for SAP error message SR136 - Function not possible when debugging in RFC context ?

  The SAP error message SR136 ("Function not possible when debugging in RFC context") typically occurs when you are trying to debug a function module or a program that is being called in a Remote Function Call (RFC) context. This error indicates that the debugger cannot be activated in the RFC context due to certain restrictions.
  Cause:
  
  RFC Context: The RFC context is designed for remote calls, and debugging in this context can lead to complications, such as issues with session management and data consistency.
  System Settings: The SAP system may have specific settings that restrict debugging in RFC calls to prevent performance issues or unintended side effects.
  User Authorizations: The user may not have the necessary authorizations to debug in an RFC context.
  
  Solution:
  
  Use Local Debugging: If possible, replicate the RFC call in a local environment (e.g., using a test program or transaction) where you can debug without the RFC context.
  Check System Settings: Consult with your SAP Basis team to see if there are any system settings that can be adjusted to allow debugging in RFC context. However, this is generally not recommended due to potential risks.
  Use Transaction ST22: If the RFC call leads to a dump, you can analyze the dump using transaction ST22 to gather more information about the error.
  Debugging Alternatives: Consider using alternative debugging techniques, such as:
  
  Logging: Implement logging within the function module to capture the flow and data without needing to debug.
  Breakpoints: Set breakpoints in the calling program instead of the RFC function module, if applicable.
  
  
  Check Authorizations: Ensure that you have the necessary authorizations to debug in the system. You may need to consult with your security team.
