How can I indicate charges and allowances in accordance with the material price escalation clause?

For charges and allowances in connection with the material price escalation clause at invoice line level, please use “Invoice line charges” (BG-28) and “Invoice line allowances” (BG-27). The calculation used for these charges and allowances can be indicated in the fields “Invoice line charge reason” (BT-144) and “Invoice line allowance reason” (BT-139).
