Bypass document pricing

Hi to all.

I have the following problem loading an invoice document buss.obj. with external data.

The problem is that the line pricing in which the document is created from the external (not SBO) program is different from SBO line pricing and then the document created in SBO have a different value vs that other. I've imagined a dangerous work-around: I supply to Document BO the data for the line and so SBO create the document. After, with an UPDATE query I change the values.

Is there someone with same problem (now or in the past)?

Thank you very much.
