Problem with optional hierachy variable in customer exit

47 Views

Hi,

I'm using a hierarchy variable in a query. This variable has the following settings

- customer exit

- optional

In the customer exit it could happen, that the hiearchy variable should be filled respectively this variable must not be used.

If I start the query and no value is set in the customer exit (the hierarchy variable is empty) it occurs an error. "Invalid value for variable ...."

Why does this happen? The variable is set to optional and not to obligatory.

Has anyone an idea?

best regards
