Cost spilit is not happening Costing based COPA

Dear All,

Please give me some hints on this

we are using costing based copa

We have booked the cost in Cost centers and allocated to Business process using T.CODE : KSU5

We have allocated cost from Business process to Products using T.CODE: CPAE

we have created the COPA Report and executed in KE30 now cost is showing in Value field which was configured in Transaction : KEI2

but cost needs to be updated as per cost component split but it is not happening( we have done cost component split configuration also)

Thanks&Regards,

Madhav.
