Plan price is mssing in KSPI

Dear SAP experts,

I already done KP06 ( for cost element planning) , KP26 ( for activity output planning) and KSS4 ( for splitting).

I already entry the data.

The splitting is also running well.

But when I run KSPI, the fixed price column is zero.

There is no error..

Could anyone help me....how can this happen?

Best regards,

Anulekha
