• What is the cause and solution for SAP error message EU192 - Only program types M, 1 or F can have user interfaces ?

  The SAP error message EU192 indicates that a program type that does not support user interfaces is being used in a context where a user interface is expected. Specifically, the error states that only program types M (Module Pool), 1 (Report), or F (Function Module) can have user interfaces.
  Cause:
  This error typically occurs when:
  
  You are trying to create or modify a program that is not of the correct type (e.g., a type that does not support user interfaces, such as a type S for a simple report).
  You are attempting to use a program type that is not designed to have a user interface in a transaction or screen that requires one.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Program Type: Verify the type of the program you are working with. You can do this by checking the attributes of the program in the ABAP Workbench (transaction SE80 or SE38).
  
  
  Change Program Type: If the program type is incorrect (e.g., it is set to type S), you may need to create a new program with the correct type (M, 1, or F) that supports user interfaces. 
  
  
  Modify Existing Program: If you have access to modify the program, you can change its type to one of the supported types. However, this may require additional adjustments to the program's logic and structure.
  
  
  Use Transaction Codes: If you are trying to execute a transaction that requires a user interface, ensure that you are using the correct transaction code associated with a program of type M, 1, or F.
  
  
  Consult Documentation: Review SAP documentation or consult with your SAP Basis or ABAP team for guidance on the appropriate program types and their usage.
