@battk The fields do exist though! They are custom transaction line fields and are on all 6 transactions types I mentioned. The code that is loading/submitting the record is below. We are also saving the arrGrantDetails array into a custom record to track our changes directly before this, which I have confirmed contains the correct values of objLineData.grant1, objLineData.amount1, etc. so I know the array isn't returning empty. var objRec = nlapiLoadRecord(stRecType, stRecId); for(var ii = 0; ii < arrGrantDetails.length; ii++) { nlapiLogExecution('DEBUG', stLoggerTitle, 'arrGrantDetails[' + ii + '] = ' + arrGrantDetails[ii]); if(arrGrantDetails[ii] != 'null') //this is really a string 'null' { var objLineData = JSON.parse(arrGrantDetails[ii]); var line = objRec.findLineItemValue('expense', 'line', objLineData.lineid); objRec.setLineItemValue('expense', 'custcol_css_grant1', line, objLineData.grant1); objRec.setLineItemValue('expense', 'custcol_css_grant1_amt', line, objLineData.amount1); objRec.setLineItemValue('expense', 'custcol_css_grant2', line, objLineData.grant2); objRec.setLineItemValue('expense', 'custcol_css_grant2_amt', line, objLineData.amount2); objRec.setLineItemValue('expense', 'custcol_css_grant3', line, objLineData.grant3); objRec.setLineItemValue('expense', 'custcol_css_grant3_amt', line, objLineData.amount3); } } var stRecId = nlapiSubmitRecord(objRec, false, true); Then it's getting logged that this transaction with internal Id = stRecID was updated.

looking at the code, it never should have worked with journal entries or deposits,
