Question

EDIT#2:

I've decided to try and batch the copy-paste operations that run after all the emails are fired. In previous posted code, in the last lines of every loop, I copied and pasted the items from each purchase order ("Email" sheet) to another ("AsignRec"). Now, what I want to do is store the items from "Email" sheet in every loop to a Javascript array, and paste all together into "AsignRec" at the end, just once.

However, I'm still not doing it right. I'm stuck at the final pasting/setValues(). I believe the array is correctly formed, as it has a length of 49, which is the number of unique SKUs to be sent out to suppliers. Still, at the setValues([OCitems]) line 185, I get the error "Incorrect range height, was 1 but should be 49 (line 185, file "TestArrayMultiple4")".

I assume this means the destination/output range is not the same size as array/input (called OCitems). I don't see why though, since I defined the length of the output range using OCitems.length. I am missing something, and not sure what.

This is the important bit of the code, and full code below. Same GDocs link as before, script file TestArrayMultiple4 , lines 160-185. https://docs.google.com/spreadsheets/d/1yzvMTh0VYhRhiexNzQPIjTwz1FCMq4XnbpGvCF1FYu8/edit#gid=436022027

    /// Get Range we want to change to creating Javascript array and paste at end only

var OcNoHeader = sheet.getRange("B9:J" + MaxTableRow).getValues(); // get items to send to supplier from "Email Sheet"

// if supplier number is 1, create array "OCitems" by storing OcNoHeader. If not supplier #1, then append to existing array "OCitems"

  if(y == 1){
    var OCitems = OcNoHeader}
    else
      {for(j=0;j<OcNoHeader.length;j++){
      OCitems.push(OcNoHeader[j]);
  }}


  Logger.log(OCitems);
  Logger.log("OCitems length = " + OCitems.length)

  debugger;

i++; // after firing email, y+1 to go to next supplier
Logger.log("i++ IF =" + 1);

Logger.log("new i ELSE =" + 1)

debugger;

} // only do while x = max number of suppliers reached
  while (i < x);  

  sheet3.getRange(3, 3, OCitems.length, 9).setValues([OCitems]); // paste operation, NumRows set equal to length of array

=========================

EDIT#1: Worked on improving performance using getValues of several cells instead of doing individual getValue() several times over. Unfortunately, this hasn't reduced the execution time in a stable or noticeable manner (sometimes it finished before 6min, sometimes not).

Posting code below (you can access it in script file " TestArrayMultiple2 " in new Sheet shared below ):

Using Execution transcript, I see that although the execution time of the getValue() lines that were previously taking very long has basically been reduced to zero, other lines of code are now taking more time and killing the gain achieved from the batching other getValue().

There are still 4-5 "individual" getValue() on specific cells (much less than before), but I don't understand why they would take so long. So it seems even if I removed the remaining "individual" getValue(), if only one remained, it would take even longer.

Seems to me it has something to do with caching (and I'm sure I don't fully understand this concept), for the following reasons: 1) It is always the first getValue() in the loop which takes the longest. 2) I tried to go down a different route, by changing the code for the copy/paste operation which occurrs after all emails are sent (line 150 in "TestArrayMultiple2" script file). I basically try to create an array which gets fed with more data at every loop (append/push method) but doesn't paste within every loop - the idea is to paste all the data at the end, after finishing looping. I still don't have it right (this second script file is the last one, "TestArrayMultiple3" ), but I can see the emails get fired off much faster.

Once again, your help would be much appreciated.

ORIGINAL POST

I wrote a Google script to automate the purchase order process to several suppliers. The process takes a list of products (from sheet ListaProductos), formats the product info into an email format (sheet "Email"), sends the emails, and does some copy/pasting into other sheets of the same spreadsheet. However, I always run into the execution time at around 75% of the script . I'm fairly new to this, have been reading up but frankly don't know what to try next.

Answer 1

I see the problem in this part of code:

do { 
  // read info from the sheet
  range.getValue();
  // more code here...

} // only do while x = max number of suppliers reached
  while (y<x)

Operation getValue takes much time to run. Best practice is to use the whole range:

var data = sheet.getDataRange().getValuses();

and then use data as source for further calculations.
