Common problems and their resolution:
- You are trying to post a supplier invoice with GL account items, but the gross amount of the invoice does not match to the sum of item amounts.
- Please check that you send the item amount for GL account lines via the XML tag <PriceCalcuation>.
- A common misunderstanding is the usage of <Amount> for GL Account lines (without purchase order reference).
- You are trying to enter a cost center for the accounting coding block assignment, but the cost center is not recognized by the system.
- Please note: The XML tag <CostCentre> expects a concatenation of controlling area and cost center ID and not only the cost center ID itself.
