[ic] percentage in pricing table and dealer price

[interchange-users@interchange.redhat.com (Ludek Mokry)]

Hello,

According documentation I can use N.NN% (or -N.NN%) in pricing table to
modify price according quantity (or in product table dealer price field to
get dealer price). But I can't make it work. 

If I enter discounted price instead of percentage to pricing table
everything is working properly.

Pricing table which doesn't work:
sku	price_group	q2	q5	q10	q25	q100	w2	w5
w10	w25	w100
00003	STANDARD	-10%	-20%	-30%	-40%	-50%	-10%	-20%
-30%	-30%	-50%

Please advise.

Thanks.
