Sounds like you may need to move those fields into the portal's table, but before we consider that, a crucial question:
Once you have made the selections in the Hierarchical CVL fields in red, should these apply to multiple rows of the portal or will you normally be making different selections from them for each row that you add?
It looks like you have made different selections each time, but since I cannot read your language, I am asking to be sure.
And on what table is your portal based?
Different selections for each row, e.g.:
Other Portions/ Number
Category Type Brand specif Presentation pers Price of units Price
Snack Cookies Oreo chocolate box 20 $10 2 (2*$10=) $20
Snack Bread Bimbo piece 10 $20 3 (3*$20=) $60
Beverage Soda Coke 2 L 10 $15 1 $15
Beverage Water Ciel 350 ml 1 $10 4 $40
Food Soup order 10 $100 1 $100
The blue information is the one that I would like to be written automatically from the input information
Need to see your tables and relationships again. And I need to know in which table you have set up with the "blue" Information so that it can be looked up here.
Is the layout based on Elecciones or is the portal based on Ellecciones?
I have a Third table, called general data (the one that is in grey). Which has the Name and general details of the meeting. It is based on that one.
And the portal in Elecciones.
The position of Input original in your graph seems odd. To me, based on limited information, that Ellecciones should link to general data directly. But whether you make that change or not, you should add an occurrence of Input to your graph Linked to Ellecciones by each of the "red" fields. Then you can set up fields in Eleccions that auto-enter the blue data from this added occurrence of Ellecciones. You cannot use the current occurrence of Input for this given it's position in the relationship graph.
