KP98 Enhancement EXIT_SAPMKPT4_010

Hi Experts,

I have a requirement to enhance the KP98 ( Actual to Plan copy ) to include secondary postings. Could you please guide me to do this? if can please provide a sample code. Specially i can't understand how to handle the different currencies and where to get the secondary postings.

I found the following article but that gives me only the background info about the exit. I failed to find any other information even in SCN.

if you need more info about my sap system version and release level please let me know.

Thanks in advance.
