In Pricing Procedure customizing, we can define a number for Requirement ( routine ) for each condition type. Requirement is used to programmatically control whether a condition type could be involved in condition determination.
2 means Item with pricing.
The way to find out implementation for routine 2:
Tcode VOFM, Requirement->Pricing:
Click F5:
KOMP-KPOSN: condition item number
KOMP-PRSFD: X - use standard approach to carry out pricing
KOMP-KZNEP: identify the price type which must be excluded for condition check
