Hi Deepu
You can follow the below steps:
1. Include the Baseprice and surcharge on your existing Pricing procedure and have these conditions copied from EDI as ZBS3 and ZBS4.
2. Add a new requirement routine on ZBS1 and ZBS2 to deactivate them (set KINAK to 'X') when ZBS3 and ZBS4 exist. KONV-KINAK = 'X' for a line item indicates condition is inactive and hence won't be considered during pricing determination.
Thanks,
