Decimals planning problem

Hi experts. I've a problem when planning a key figure with more than 4 decimals places. I've search the forums but I still don't find the solution.

My key figure is FLTP and the value that it should plan is like 0.0000045 for example. After pressing the transfer button on BEX, the key figure changes it's value to 0.000000 and does the maths with this value.

I have the max precission value cheked on other properties of the key figure. The key figure is a ZInfoobject. Any ideas?
