As much as SAP has problems, this is a solved problem there. In my experiences sometimes this is implemented incorrectly, but discovered very soon, as it's about money. I encountered this when people made some simple calculations on the frontend-side then submitting to the ERP system, where it was discovered because of the emerging inconsistencies.
