I am using Omni Price in my GP 10.0 environment. Can I use Integration Manager to pull in SOP invoices?
Yes, but you would need to recalculate each Invoice that you imported via the Extras menu. Or, if the invoices are all in the same Batch, then you can recalculate the Batch.
You can import using eConnect and our API for Omni Price through the back-end.
Make sure you are on the most recent build of Omni Price.
