Copy and Paste the Row based on condition in another Sheet - google-apps-script

Question

I've been looking on this website and others for an answer but can't find anything relevant and was wondering if someone could help please.
I've using Apps Script - Google Sheets.
The main sheet was called "M-Front". So it got quotation number with revision number. If new quotation, the revision will be zero. If we revise the quotation once, the revision number will be 1.
For example, GE-2108-0271-Rev.0 is new quotation.
If we revise once, it would be GE-2108-0271-Rev.1.
I have other sheet called "M-Items".
Let say for GE-2108-0271-Rev.0, we have three rows for that quotation number represent three items for that quotation.
My intention is , if new revision was made in "M-Front". It will be GE-2108-0271-Rev.1. But how to detect the last row from "M-Front" quotation number and in "M-Items" we copy and paste the rows. In this case, 3 rows/items. and make the quotation in "M-Items" from GE-2108-0271-Rev.0 to GE-2108-0271-Rev.1.
M-Front
M-Items
The Script i've stuck
function CopyRange() {
var sourcespread = SpreadsheetApp.openById('1Zgs1jzjIeaBpd5Ms7emQgxhVJBMtlEOlDNDfxlhSRiY'); //replace with source ID
var sourcesheet = sourcespread.getSheetByName('M-Front'); //replace with source Sheet tab name
var destspread = SpreadsheetApp.openById('1Zgs1jzjIeaBpd5Ms7emQgxhVJBMtlEOlDNDfxlhSRiY'); //replace with destination ID
var destsheet = destspread.getSheetByName('M-Items'); //replace with destination Sheet tab name
var testrange = sourcesheet.getRange('M:M').getLastRow;
var testvalue = (testrange.getValues());
var data = [];
var j =[];
for (i=0;i<testvalue.length;i++) {
if (testvalue[i] /= 0) {
data.push.apply(data,sourcesheet.getRange('A:A').getValues());
//Copy matched ROW numbers to j
j.push(i);
}
}
//Copy data array to destination sheet
destsheet.getRange(destsheet.getLastRow()+1,1,data.length,data[0].length).setValues(data);
}

You might want to try the below script:
function CopyRange() {
var sourcespread = SpreadsheetApp.openById('1Zgs1jzjIeaBpd5Ms7emQgxhVJBMtlEOlDNDfxlhSRiY'); //replace with source ID
var sourcesheet = sourcespread.getSheetByName('M-Front'); //replace with source Sheet tab name
var destsheet = sourcespread.getSheetByName('M-Items'); //replace with destination Sheet tab name
var mcol= sourcesheet.getRange('M1:M').getValues();
var acol = sourcesheet.getRange('A1:A').getValues();
var ccol = destsheet.getRange('C1:C').getValues();
var acol2 = destsheet.getRange('A1:A').getValues();
var mvalues = mcol.filter(String);
var avalues = acol.filter(String);
var cvalues = ccol.filter(String);
var avalues2 = acol2.filter(String);
for (let i=1; i<mvalues.length; i++) {
if (mvalues[i][0] != 0) {
if (avalues[i][0] == avalues2[i][0] && mvalues[i][0] == cvalues[i][0] - 1)
var valuescopy = sourcesheet.getRange("RANGE_FOR_THE_VALUES_TO_COPY").getValues();
destsheet.getRange("RANGE_WHERE_TO_PASTE").setValues(valuescopy);
cvalues[i][0]++;
}
}
}
It is important to note the following points:
getLastRow will return the last row for the entire range - this means that the rows which have no values are also included this;
In order to retrieve the rows which contain a value, the filter has been used.
getValues method will return a 2D array, so you will have to access an element in this way array[i][j].
Moreover, please bear in mind that you will have to adjust the ranges properly such that they match your needs accordingly; more specifically, the range from where you want to copy the values and also the destination range.
Reference
getLastRow();
getValues();
getRange(row, column, numRows, numColumns).
