Additional fields in EBAN and EKPO

Hello,

we have the requirement, to add some new fields in our purchasing process (i.e. in purchase requisition and purchase order). I want to add the additional fields in customer includes CI_EBANDB (for PR) and CI_EKPODB (for PO).

My question is: will SAP handle the transfer of the content of this additional fields from the PR item to the PO item automatically (e.g. via move-corresponding), when creating the PO from the PR (e.g. in ME58, ME59, ME21N, …), if we use the same fieldnames in CI_EBANDB and CI_EKPODB, or must I handle the transfer by myself?

If I have to handle it by myself, is there someone who already realized it, who can give me some informations, on her/his solution?

We're on SAP release ECC6.0.

Thanks in advance!

Best regards

Stephan
