I am trying to add new fields to TC KO01/2/3.
I've read the documentation and did not understand.
I've already created my fields in the CI_AUFK structure.
now I can write the coas-zmenge into the table. but on the user-define screen '0100' , the field of coas-zmenge is still blank,can't display with the value.
Can you give me an example of how to write in EXIT_SAPMKAUF_002 PBO?
