Price (Catalog) COND_INACTIVE

Hi,

In the purchase order change version, i can see the above above subject message i.e Price (Catalog) COND_INACTIVE (Check box ticked)

How to make Catalog price condition Inactive.

I am getting below error while changing purchase order :in application monitor

PurchOrder xxxxxxxxx: Purchase order still contains faulty items

02.06.2009 14:17: 16 PurchOrder 6500031274: Net price must be greater than 0 (Zero)

Is this because of above setting?

Thanks,

Jai
