How to post invoice data into peachtree from a custom application

[amigo02]

Can anybody show me the <b>peachtree table structure</b> and how to create and <b>post</b> a new invoice data into those tables <b>from another application</b>.

I have downloaded pervasive v8 and I am able to see the tables and data in it. But I was unable to find any invoicing information there.

I have never been worked with btrieve before and it looks like it is quite different than other database systems.
