Go to TCode CMOD and select an existing project / create a new project.
Select enhancement assignment and give the name EXIT_SAPMM07M_001
Save the change.
Then enter again and double click on the name provided above. Inside there will be an INCLUDE ZX*****
Double click on that include, the system will ask to create a program. Accept it.
Now you have the open field to make your validation.
