My requirement is to add a new screen at item level of ME21n transaction using BADI "ME_GUI_PO_CUST" / "ME_PROCESS_PO_CUST". I have gone through the sample codes and have implemented the same. I coule see the screen and evry thing is working well.
BUT as per my requirement -
I have more than 10 custom fields to be added on the new screen, so how do i map these fields to meta fields(as this is restricted to 10) ?
I need the screen to appear only when order type is XX (Some value), How do i acheive this ?
Do all fields to be displayed on the screen need to be in the structure ( mepo_badi_exampl in the sample code), for instance If I add VBELN (Contract nr) on the screen and when user enters this its corressponding description should also be disaplyed. In this case both VBELN and Description fields need to be part of the structure (mepo_badi_exampl in the sample code)?
How do I provide F4 helps on the screen fields, can i do this in Process On Value Request of the screen, Does this BADI support this ?
Sample code on any of this would be of great help ....
Looking forward for reply.....
