Transport Export DataSource

Dear all,

I have an Export DataSource from one Cube to an ODS. Via Transport it does not

get activated in QA. There I get an error that the Extract Structure is not defined.

Althought generated and also reassigend in DEV, it is not getting activated.

How do I get an Export DataSource transported and active in QA as well Prod?

Many thanks in advance!

Cheers,

Claudia
