Google Script: print school schedule data for each teacher - google-apps-script

Question

This is my first question here. I have searched the site to the best of my knowledge, but haven't found any other examples of my question.
Here is the Google Sheets file
https://docs.google.com/spreadsheets/d/1HxyhoxuPK8H8_vhLg0ZZ-THyOn1cn9nPYRyls8y47iM/edit?usp=sharing
I have 2 sheets in the same Google Sheets document.
The first, "schema" contains a base-school schedule for a teacher, with different classes in different blocks. This needs to be replicated, so that all teachers has this exact setup - so that all unique users have the same 50 lines of schedule data - only with their allocated classes.
The second sheet contains information about the users. Each line contains a UNI-login username and their designated class 1a-1, 4a-1 and 8a-1 for user uni12345 for example. 1a-1 needs to replace 1, in "uni12345"'s schedule data.
I would like all these data (a lot of lines) combined into one sheet, fx. called "combined" - but you get your pick on the name :-)
I have made a Combined Example sheet, that presents how I would like the output for user1+2 in the list.
If the question already is partly answered elsewhere, I'll be happy to look at that also!
Edit:
Since my original question I have made it work - only now I'm hitting the 6min script exectution time limit. Any way around that, eg. optimization?
function merge() {
var CurrentDate = new Date() ;
var CurrentDateString1 = Utilities.formatDate(CurrentDate, "GMT", "MM-dd-yyyy HH:mm:ss") ;
var ss=SpreadsheetApp.getActive();
// var mergeSht=ss.getSheetByName(CurrentDateString1);
var users=ss.getSheetByName('users');
var schema=ss.getSheetByName('schema');
var mergeSht = ss.insertSheet();
mergeSht.setName(CurrentDateString1);
var usersValues = users.getDataRange().getValues();
var schemaValues = schema.getDataRange().getValues();
var counter = 1;
for(var n=1; n < usersValues.length ; n++){
var usersValue = usersValues[n];
var uniName = usersValue[5];
var levelInd = usersValue[2];
var levelMellem = usersValue[3];
var levelUdsk = usersValue[4];
// Logger.log(usersValues[n][5])
for(var i=1; i < schemaValues.length ; i++){
var schemaValue = schemaValues[i];
if (schemaValue != null && schemaValue.length > 0) {
var level = schemaValue[3];
var subject = schemaValue[4];
var room = schemaValue[5];
var day = schemaValue[6];
var position = schemaValue[7];
var levelAfd = getlevel(level,levelInd, levelMellem, levelUdsk);
Logger.log(levelAfd);
// print
var row=[];
row.push(counter++,'','unilogin:'+ uniName, levelAfd, subject, room, day, position);
mergeSht.appendRow(row);
}
}
}
}
function getlevel(level, levelInd, levelMellem, levelUdsk){
switch (level)
{
case 1:
return levelInd;
case 4:
return levelMellem;
case 7:
return levelUdsk;
}
}

Here's something else you could try:
This code creates a new array which avoids having to push each row one by one. Instead, at the end in loads the entire mergeSht all at one time.
function merge()
{
var CurrentDate = new Date() ;
var CurrentDateString1 = Utilities.formatDate(CurrentDate, "GMT", "MM-dd-yyyy HH:mm:ss") ;
var ss=SpreadsheetApp.getActive();
// var mergeSht=ss.getSheetByName(CurrentDateString1);
var users=ss.getSheetByName('users');
var schema=ss.getSheetByName('schema');
var mergeSht = ss.insertSheet();
mergeSht.setName(CurrentDateString1);
var usersValues = users.getDataRange().getValues();
var schemaValues = schema.getDataRange().getValues();
var counter = 1;
var mergeA=[];//Small change
mergeA.push(['H1','H2','H3','H4','H5','H6','H7','H8']); //First row is headers
for(var n=1; n < usersValues.length ; n++)
{
var usersValue = usersValues[n];
var uniName = usersValue[5];
var levelInd = usersValue[2];
var levelMellem = usersValue[3];
var levelUdsk = usersValue[4];
// Logger.log(usersValues[n][5])
for(var i=1; i < schemaValues.length ; i++)
{
var schemaValue = schemaValues[i];
if (schemaValue != null && schemaValue.length > 0)
{
var level = schemaValue[3];
var subject = schemaValue[4];
var room = schemaValue[5];
var day = schemaValue[6];
var position = schemaValue[7];
var levelAfd='';
switch(level)
{
case 1:
levelAfd=levelInd;
break;
case 4:
levelAfd=levelMellem;
break;
case 7:
levelAfd=levelUdsk;
break;
default:
levelAfd='';
break;
}
if(levelAfd)
{
mergeA.push([counter++,'','unilogin:'+ uniName, levelAfd, subject, room, day, position]);
}
}
}
}
mergeSht.getRange(1,1,mergeA.length,mergeA[0].length).setValues(mergeA);
}
