Hi,
You could have them in the following way:
-----------------------------------------------------------------------------------------------------------------------------------
Step # / Cond. Type / Text From / To / Sub Total
-----------------------------------------------------------------------------------------------------------------------------------
AAA Net Price
XXX ZS18 Currency Surcharge AAA
BBB Net Price w. Cur. Surc. AAA XXX Y - One of the not used one.
CCC ZS10 Packing Surcharge BBB
DDD Net Price W. All Surc. BBB CCC
-----------------------------------------------------------------------------------------------------------------------------------
Please note that you should be aware of whether these surcharges are taxable & act accordingly.
Get back to me if you need any further clarification.
Should be self explanatory.
Thanks.
