FM/BADI to create INFORECORD

Hi all,

I've searched a lot, but I'm unable to create an INFORECORD.

When creating a quotation, I need to check if the materials have an inforecord, if they don't have an inforecord I have to create it.

I'm using ME_PURCHDOC_POSTED badi to input my code.

How do I accomplish it?

Witch FM or BAPI do I have to use and how?

If you have some sample code, I appreciate it a lot!

Best regards,

Carlos Constantino
