I have to add one text field in PA2001 infotype. I am using PM01 transaction.
I clicked the single scrn tab (enhances single screen of standard infotype ).
In this screen I gave the infotype no and under subobjects I choose the customer include radio button and then pressed the edit button.
After doing this, a message at the bottom of the screen is coming as CI_P2001 does not exit. check name.
Therfore I am not getting the structure to add the field.
