How to reference to a local variable in my editable grid

Question

Hi! I have created an editable grid with previous data (stored in my local variable) 
 To create an editable grid from scratch, I used to put "fv!item..." in the value and saveInto parameters (so that when the user interacts, the value was saved). 
 But in this case, I just want the grid to show the data of my local variable and save it in another record/ruleInput/localVariable 
 How can I configure my code in order to manage this? Should I use the a!save function? Should I "point" to each field/column of my local variable without using the "fv!item"? How? 
 
 I leave my code here. I think that I could omit the operations between columns in "Cantidad", "Precio Unitario" and Importe, because I&acute;m querying the values directly with my local variables (my local variable is created by quering a previous editable grid). But for me the most important thing is being able to point to my local variable and save correctly the values without user interaction with the grid 
 Thanks a lot!

One important thing to note about Appian is that saves on an interface only occur when there is a user interaction. So, usually if you want to save information without the user needing to update anything, the easiest approach is to use a button click to trigger the save. 
 It looks like you're close - you have a save into that is taking the information from your local variable and saving it into the rule input. I think you just need to make sure you have all the information from your local variables and save it into any associated rule inputs. 
 In addition, if you don't expect users to interact with the grid, you can likely remove all of the saveInto parameters there (since you won't need to update anything).
