• What is the cause and solution for SAP error message EC150 - Function codes are not permitted in the form ?

  The SAP error message EC150, which states "Function codes are not permitted in the form ", typically occurs when there is an attempt to use function codes (like buttons or actions) in a context where they are not allowed, such as in certain types of screens or forms.
  Cause:
  
  Improper Use of Function Codes: The error usually arises when a function code is defined in a screen or form that does not support it. This can happen if the screen is designed for display purposes only or if the function code is not properly defined in the program logic.
  Screen Type: The screen type might not be compatible with the function codes being used. For example, if you are using a dialog screen that is not intended for user interaction.

  Check Screen Attributes: Review the attributes of the screen or form where the error occurs. Ensure that it is designed to accept function codes. If it is a display-only screen, you may need to change its type or remove the function codes.
  Review Code Logic: Look at the ABAP code associated with the screen. Ensure that function codes are only being used in appropriate contexts. If necessary, modify the code to handle function codes correctly.
  Use Correct Function Codes: Ensure that the function codes you are trying to use are valid for the context of the screen. If you are using custom function codes, verify that they are defined correctly in the program.
  Debugging: If the issue persists, use the SAP debugger to trace the execution flow and identify where the function code is being incorrectly invoked.
