Hi João,

Regarding your 2nd issue, you need to add a OnChange action to your dropdown:

And then on the action you will need to assign the new value you want to the Code:

I don't know if you will need to pick this value from the Database or not but in the end you should assign the value to this variable so it takes the new value on the screen.

Kind regards,
João

Hi João

Thank you for your feedback.

I created the action but I don't understand quite well the last part. The idea is to fetch the "Rubrica Geral" code and display it.

At this time, when I create a new "Rubrica Orçamental", when I change the dropbox from "Departamentos", automatically shows the first "Rubrica Geral Code", without choosing the "Rubrica Geral"

Hi João,

Ok, so to answer your need, I created a query that gets the details of rubrica geral based on a variable.

Now, on the action binded to the change of the dropdown, 1. update the value of the variable created above and refresh the query to get the new code and then assign to the variable you want to update on the screen:

The OML follows in attachment so you can look at it with more detail.

Kind regards,
João

João once again thank you for your support.

I made the changes you referred, I saw your .oml (that is working as it should be) but something is missing in mine that i can't find. 

As you can see, the action is similar to yours but mine don't change the code...  :S
