Copy SO field to PO

Hi all,

We have a requirement to copy the incoterms from sales order during PO creation. I am using enhancement MM06E005. I am looking at exits EXIT_SAPMM06E_008 and EXIT_SAPMM06E_012. In debugging mode, when i change ekko manually, the screen is displaying the value i passed but from the exit itself there is no parameter to pass/change this value (EKKO-INCO2). Upon saving EXIT_SAPMM06E_012 gets triggered. Just the same don't know which parameter to pass to change this field.

Any idea how to get this requirement done?

Thanks.

Regards,
