Cost Component issue

Hello

I have a doubt: I tought that, to recover some component of a product I needed to do this:

1. Go to MBEW, retrieve field KALN1

2. GO TO KEKO and find the KADKY to retrieve the date

3. Go to CKIS to retrieve the cost components

This worked in 4.5 for me,but in 4.7 I have a material that, if I go to CK13 the cost components are displayed, but this information does not exist in CKIS

How does this work for newer versions of sap?

Thanks in advance
