I am trying to delete a sublist line with SS2.0 but the line isn't being removed for some reason. Here is the code I am using: for (var j = 0; j < rec.getLineCount('recmachcustrecord_billpayment_id'); j++) { rec.removeLine({ sublistId: 'recmachcustrecord_billpayment_id', line: j }) } Any idea why the lines aren't being removed?

Do you have to save() ?

I do rec.save() once I add the other lines on - I shouldn't have to save() before I add other lines for this to work right?

no, just save once per script execution

The record is in dynamic mode, I wonder if that could be affecting it

ill give the general advice: remove backwards

the intent is remove every line on the sublist, based on the lineCount

think of what happens to the rest of the lines when you remove 0th line, but now

j

is 1

ah, good point

well, you can probably simplify that to:

while (rec.getLineCount("recmachcustrecord_billpayment_id") > 0) {
  rec.removeLine({
    sublistId: "recmachcustrecord_billpayment_id",
    line: 0
  });
}

yup, that was the trick! works now - thanks for the help everyone
