condition type values not added in standard cost run

hi,

for all materials we are maintaing standard cost, due to this VAT non ded and CST is going to price varieance account. so we have included in info record with separte condition type for VAT non ded and CST, then in the valuation variant(okkn) under delivery cost we have incudeded those two condition for adding that cost to materials (for STD cost run). While running the standard cost estimate this two condition type amount is not adding to the material cost. Can any one help me in this regard.
