Manual Pricing Components Errors while request external pricing in sales quote

Hi All,

We have integrated C4C with ERP via PI. And for the requesting external pricing for sales quote in the C4C, the system returns some errors while manually adding the price components for some condition types (some condtion types no errors, and can be added sucessfully).

Error: Condition type XXX is a structure condition (KDUPL = A);

          Operations with condition of type F not allowed (XXX)

However, we test them directly in the ERP, no such above errors.

So does anybody knows why those errors raised in C4C? and is there any impact if leave condition category (say F) as blank?

Is there any impact if leave structure condtion as blank?

Begards,

Qiang
