Little measure problem

[_chris_]

Hi,

I have two tables having a relationship:

In some rows the key field is empty:

I have a measure which sums up a field from the other table. However, it also shows values for the rows with no VorPosId. How can I achieve to have blank values there?

Thx Christian
