You have created a Follow up Invoice from an existing invoice from a scheduled invoice request and the suggested values for pricing are incorrect.


SAP Business ByDesign

Reproducing the Issue

  1. Create a contract with one line item of type "Service - Fixed Price without actuals".
  2. Tick the Price Per Period indicator.
  3. Create an invoice schedule with multiple dates.
  4. Invoice the scheduled invoice request from the contract.
  5. Create a follow up invoice/credit memo or correction invoice for the original invoice.

In some cases the pricing is taken over incorrectly.


  • When the price per period indicator is ticked, each line in the invoice schedule is broken down to quantity percentage.
  • We store the percentages in rounded values, if necessary.
  • The original invoice is calculated with the original values.
  • Follow up invoices are generated with the rounded values.
  • Example:
    Line item 10 is entered with price 320 EUR.
    One date for line items 10 is entered with 1EUR.
    The system calculated the quantity for that invoice request -> 1/320 = 0.003125.
    The information is rounded to 0.003.
    The original invoice is generated with the correct values.
    Follow up invoices calculate with the rounded values -> 0.003 * 320 = 0.96 EUR.


  • This is currently a limitation in the system and will be changed in a future release.
  • To avoid this behavior, make sure to adjust the suggested quantity values in follow up documents.
  • Cancellation invoices are not affected. You can cancel the original invoice and re-invoice it.
