Implementing ME21N / ME22N screen exit (Enhancement MM06E005)

Question

I've just implemented enhancement MM06E005 and have extended a new field to CI_EKKODB. The subscreen is in place and the project has been activated without issues. I can populate the DB via the new field in 'customer data' tab. The only problem I have is I don't see my new value after saving the PO and re-accessing it in change mode ME22N. The new field is blank. I can see the record's new field has the value in SE16N and I see the value when debugging EXIT_SAPMM06E_006. My assignment statement in EXIT_SAPMM06E_006 for the new field is similar to: i_ci_ekko-zzvbeln = i_ekko-zzvbeln. What have I missed?

Hi steve ,
In addition to the function exit u r doing , u have to code the bellow exit also .
See the documentation of this exit , it explains u clearly in the document.
EXIT_SAPMM06E_006  Export Data to Customer Subscreen for Purchasing Document Head
EXIT_SAPMM06E_008  Import Data from Customer Subscreen for Purchasing Document
The dynpros are linked to the standard program via function modules.
There are function modules that provide your subscreen with data
(export) and function modules that fetch data from your subscreens
(import).
o   Header screens:
    -   EXIT_SAPMM06E_006   Export data to customer subscreen for header
        (PBO)
    -   EXIT_SAPMM06E_007   Export data to customer subscreen for header
        (PAI)
    -   EXIT_SAPMM06E_008   Import data from customer subscreen for
        header
