RE: How to create custom html popup (not by using suitelet) in netsuite salesorder and getting all line data on that popup .
Creating the custom html popup field with submit button in netsuite sales order and getting all the line level data on that popups . And When the user Clicks on submit the particular line level sublist should be get updated .
Any Ideas will be appreicieted .
You can use SuiteScript 1.0 apis like nlapiGetLineItemValue to get your data. Or if you can handle the asynchronous of require, you can use require to get access to N/currentRecord, get the currentRecord, and use methods like getSublistValue.
Same general idea for setting line item values, for SuiteScript 1.0, use nlapiSelectLineItem to select a line item, then set its values using apis like nlapiSetCurrentLineItemValue, then use nlapiCommitLineItem to commit the line when you are done. There are equivalents for SuiteScript 2.0.
