Perform a abap programm with a z transaction..bounce back to main sap menue

Hello,

i have created a easy ABAP programm for analysis. Just a join over a view tables and output. I can execute the programm with se38 and run. I also created a Z transaction code for the programm with the transaction SE93.

I am able to run the programm with SE38, but when i try to execute the programm with the direct Z* transaction code the programm bounces back to the sap main menue.

Anybody has an idea?

Thank you & Greetings
