Question

Hi if I have certain run time conditions to check before defining some upstream tasks can I still use the same task variable for dependencies

Tsang Yong · Answer

```if condition task A = run task a run task b upstream tasks task a lt will this work ```

Tsang Yong · Answer

or would I need to do this ```if condition task A = run task a run task b upstream tasks task A else run task b ```

Hi < Tsang Yong> thanks for the question I guess the question depends on whether you want run task b to always run The should give you a bit more information and background on when things will run or not
