Hide or remove line FC

David, not sure what your specific requirements are, but I did this in the Grant Management application, which is outlined here: https://www.lawsonguru.co...t-All-Together.aspx.

Here are some code snippets showing some of the technique I used.  Basically, it figured out whether LINE-FC needed to be set to a 'C' or not.  Note that in this application, LINE-FC = D and/or A were not applicable.

First, hide LINE-FC in the form definition:
Then, when form is initialized, set LINE-FC to blank on all rows: function FORM_OnInit() {
  // initialize line FC to blank on all rows
  for (var nRow=0; nRow < 11; nRow++) {
  lawForm.setDataValue("LINE-FC","",nRow);
  }
}

Finally, when posting the transaction, use some logic (in this app it was based on there being a LINE-NBR value on the row), set LINE-FC to 'C'

function FORM_OnBeforeTransaction(fc) {
  // user clicked change; based on fields with values entered, set LineFC = "C"
  if(fc == "C") {
    zeroLinesBeforeChange()

    for (var nRow=0; nRow < 11; nRow++) {
      lawForm.setDataValue("LINE-FC","",nRow);
      if (lawForm.getDataValue("LINE-NBR",nRow) != '') {
        lawForm.setDataValue("LINE-FC","C",nRow) }
       }
  }
  return true;
}

Thanks, John. That's exactly what we needed.
