Hi, I am adding items into the purchaseorder using client script it is adding items but not committing to new line after adding first item how can I add items to the existing grid, I have below code

currentRecord.selectNewLine({ sublistId: 'expense' });

						currentRecord.setCurrentSublistValue({ sublistId: 'expense', fieldId: 'account', value: account1 });
						
						var amount1 = purchaseReq.getValue({ fieldId: 'custrecordpola1' });
						currentRecord.setCurrentSublistValue({ sublistId: 'expense', fieldId: 'amount', value: amount1 });
						
						var department1 = purchaseReq.getValue({ fieldId: 'custrecord89' });
						currentRecord.setCurrentSublistValue({ sublistId: 'expense', fieldId: 'department', value: department1 });
						
						var location1 = purchaseReq.getValue({ fieldId: 'custrecord109' });
						currentRecord.setCurrentSublistValue({ sublistId: 'expense', fieldId: 'location', value: locationId });
						
						// commit the changes
						currentRecord.commitLine({ sublistId: 'expense' });

after adding items it is showing like below image, I do not want to click on add button, is there any way to add items.

You usually have to call record.save after commitLine as far as I'm aware.

are you sure it will not save the purchase order.

It will save the purchase order. Maybe someone else can weigh in on this but I'm sure you have to call save for the changes to lines to take effect.

What’s the trigger to add these lines? was Vendor and Subsidiary set before?

^ what battk said and make sure you set them in the exact order you would set them when modifying the lines in the UI
