Screen Exit PBO/PAI Data populating problem on ME31K/ME32K (Very Urgent)

Hi,

I implemented screen exit SAPMMO6E-201 by adding field EKKO-ZMPA and it is displaying fine in the transaction code ME32K.

Problem is what ever the value entered in this custome field(ZMPA) is not geting populated any of the function exit strutures. I tried all the functional exit like EXIT_SAPMM06E_008, EXIT_SAPMM06E_007, but no where data get populating.

I observed in debug mode value is getting in one of the structure CI_EKKODB-ZMPA in EXIT_SAPMMO6E_008, but this structure is not avilable when I am assigning to one of the chainging field E_CI_EKKO-ZMPA.

Please help, how to store and display the screen exit (EKKO-ZMPA) field value into and from the data base respectively.

Thanks and Regards,

Param.
