• What is the cause and solution for SAP error message 1M146 - Customer function module may not be called up via RFC ?

  The SAP error message 1M146 ("Customer function module may not be called up via RFC") typically occurs when there is an attempt to call a customer-defined function module via Remote Function Call (RFC), but the function module is not designed to be called in this manner. This restriction is often in place for security or design reasons.
  Cause:
  
  Function Module Attributes: The function module in question is likely defined with the attribute "Not RFC-enabled." This means it cannot be called remotely.
  Incorrect Usage: The function module may be intended for local use only, and calling it via RFC violates its intended use.
  Authorization Issues: There may be authorization restrictions preventing the function module from being executed in an RFC context.
  
  Solution:
  
  
  Check Function Module Attributes:
  
  Go to transaction SE37 (Function Module) and enter the name of the function module.
  Check the attributes of the function module. If it is not RFC-enabled, you will need to modify it to allow RFC calls if appropriate.
  To enable RFC, you can set the "Remote-Enabled Module" checkbox in the function module's attributes.
  
  
  
  Modify the Function Module:
  
  If the function module is intended to be used remotely, ensure that it is designed to handle remote calls properly.
  If it is not intended for remote use, consider creating a new RFC-enabled function module that wraps the existing logic.
  
  
  
  Review Calling Program:
  
  Ensure that the program or process that is attempting to call the function module is doing so correctly and that it is appropriate to call this function module via RFC.
  
  
  
  Authorization Check:
  
  Ensure that the user or system making the RFC call has the necessary authorizations to execute the function module.
  
  
  
  Consult Documentation:
  
  Review any documentation related to the function module to understand its intended use and any restrictions.
