@hamza-sellami,tunit will accept 2 tmap as input and the rule is you should have same output schema for both tmaps inculding order of columns.
What do you expect?
Can't see any tUnite in your job so it's not easy to imagine what you want.
Furthermore it's not the same job as in your previous post.
Based on your components name you're maybe a french speaker.
In this case, double your question in french if you prefer (in the same post).
