i have an error while running depreciation Error Number: 070R Error Description: Accumulated Cost ar

while running depreciation , i am continuously getting below error

Error Number: 070R Error Description: Accumulated Cost are Zero

cost is there dated 01/05/2018 (asset cost entry )

acquisition date is 07/05/2018

depreciation start date is 07/05/2018

depreciation menthod is 01 , compute direction is 'P'

May I know what could be the reason for above error , because costs are already there in the system .

and the strange part is it calculates the depreciation and creates DEPRECIATION ENTRY AS WELL .

but on PDF it gives above error .

thanks for the prompt reply .
