Google Sheets - Identify duplicates and overwriting data - google-apps-script

Question

I've heavily edited the original question I posted, as i have solved some of the issue myself. I'm now stuck on just one thing.
function payINVOICE() {
var ss = SpreadsheetApp.getActive();
var ds = SpreadsheetApp.openById("14imcEob2qIZbH6AjGYtf16MJxbnfkhQn1ae4jR-Nzq4");
var srcSheet = ss.getSheetByName("INVOICE_ENTRY");
var dstSheet = ds.getSheetByName("INVOICE_ENTRY");
var data_range = srcSheet.getRange('B4:J100');
var data_data = data_range.getValues();
var data_clean = data_data.filter(function (r) {return r[1]});
var clear_range = srcSheet.getRange('B4:I100');
var lr = dstSheet.getLastRow();
dstSheet.getRange(lr+1, 2,data_clean.length,9).setValues(data_clean);
clear_range.clear();
}
This code checks the range B4:J100 for a value in Column B.
If there is a value and the script is run, it copies those rows onto dstSheet.
My role is marking invoices as paid or not.
The dstSheet will already contain the data, which is pulled back into the srcSheet with a query. Column K is not part of the original query.
If I mark a row as "PAID" in column K on the srcSheet, I want the code to take the data_data variable and overwrite what is already in the dstSheet, so that the query then pulls the data back into srcSheet with column J then showing "PAID".
It means I can then change column K to "NOT PAID", run the script again and it will over-write the "PAID".
This makes better sense than my last post and I am so close to achieving what I need, just stuck on this last bit.

If you simply want to monitor the changes between the two mentioned sheets, it would be much easier to use an onEdit(e) trigger which will tell you which cell has been edited.
Snippet
function payINVOICE(e) {
var srcSheet = SpreadsheetApp.getActiveSheet(); //gets the active sheet which is supposed to be source sheet
var dstSheet = SpreadsheetApp.openById('DEST_SHEET_ID').getSheetByName('INVOICE_ENTRY'); //gets the destination sheet
if (e.range.getSheet().getName() == 'INVOICE_ENTRY' && e.range.getColumn() == 11) { //e specifies where the edit has been made - therefore this if condition checks if the edit is in the INVOICE ENTRY sheet and if the column is the K column
var row =e.range.getRow(); //this gathers the row at which the edit has been made
var data = srcSheet.getRange(row, 2, 1, 10).getValues(); //this gathers the data corresponding to the row at which the edit has been made
dstSheet.getRange(row, 2, 1, 10).setValues(data); //this sets the data into the corresponding row in the destination sheet
}
Explanation
The above code uses the onEdit(e) installable trigger and the e event object. In this way, when an edit is being made on the srcSheet on the 11th column (aka K column) and the sheet name is "INVOICE_ENTRY", then the row at which the change has been made is kept in the row variable. Afterwards, the corresponding row of data is kept in the data variable; the getRange(row, 2, 1, 10) references the range for the row at which the change on the K column has been made. In order to update the dstSheet, the data value is set to the according range using setValues(data).
Installing the trigger
To make the payINVOICE(e) function trigger on an edit action, you need to install an onEdit trigger.
This is being done by accessing the project's triggers by clicking this icon:
After that, you just need to create a new trigger by clicking the Add trigger button and create a trigger with the following settings:
Trying the function
In order to try the behavior for this, you just need to make an edit on the srcSheet on the K column and this change will be reflected in the destSheet.
Note
The ranges that have been used in this script are chosen considering the fact that:
K column consists of the PAID/NOT PAID text;
The srcSheet and the dstSheet have the data wanted in the same ranges.
You might need to customize these according to your sheet and add the needed formulas/filters you have mentioned.
