COPA values not updating in KE24

Hi

We have two new condition types to get the whole sale price and the retail price of the materials which are invoiced. The whole sale prices and the retail prices are maintained in VK12.

There is a requirement to get these values in a KE30 report. Therefore to cater this requirement, we have created two new value fields and mapped the condition types to these value fields in KE4I. However when the SD invoiced is raised only the retail price is getting updated in KE24 not the whole sale price

Please let me know why this is happening and how to correct this

Thanks
