Pricing Date Missing in Condition type

Hi Friends,

While creating condition type (XX01) in M/06 for procurement, I am not finding “Pricing Date” field in control data 2 section.after "Exclusion" field
What could be reason for this?

In Control Data 1 I have chosen

1. Cond.Class as-B (Price)
2. Calculat.type as-C (Quantity)

Please let me know what i have to do to get "Pricing Date" field in condition type.

Working on SPA version ERP 6.0

Thanks,
San
