costing sheet problem

Hi ,All

I am doing the cost estimate with CK11N.

I get the wrong material price here, the price of P999 A should be 900/pc ,but now it turns out to be 1036.71=900*（1+15.19%）

and 15.19% is my overhead rate for material storage.

Anyone can tell me what should i do now to split the overhead and material price? Thanks!

By the way the number of G 1002 8888 is also wrong.
