I have a script that adds an item group via a button press. Works great but I would also like to have the quantity field update based on the unit type for certain line items in the item group and the quantity would come from a field in the transaction. When i check the console log I see that the Original Unit is blank which leads me to believe it is because it is an item group and the items are already added. Is there a way to get the unit type from items in an item group?

if (recordType == 'estimate') {
        rec.selectNewLine({ sublistId: 'item'})
        rec.setCurrentSublistValue({ 
          sublistId: 'item',
          fieldId: 'item',
          value: 1157, 
          forceSyncSourcing: true
        })
        var origUnit = rec.getCurrentSublistValue({
           sublistId: 'item',
           fieldId: 'units'
        });
        console.log("Original Unit = " + origUnit);
        if (origUnit == '2') { 
           rec.setCurrentSublistValue({ 
           sublistId: 'item',
           fieldId: 'quantity',
           value: myQuantity, 
           forceSyncSourcing: true
           })
        }
       } 
       rec.commitLine({"sublistId": "item"});

you probably want to explain this better

Yes. Was referring to Item Groups. i do see what you mean about an item group not having uom.

how do you enter uom on an item group record

I don't. I was under the assumption that once the item members loaded I could get the uom from that.

thats what i was saying about your code
