What is the difference between line and linesequencenumber?

AI generated answer (using internal Slack threads):

In NetSuite,

line

and

linesequencenumber

are two different properties related to line items in a transaction. The

line

property, also known as Line ID, is a unique identifier given to each line item when it is created. This ID does not change until the line item is removed, regardless of any operations performed on it (like editing the line or inserting a line item above). If a line item is removed and another line item is inserted to replace it, the new line item will have a different Line ID. On the other hand,

linesequencenumber

holds the internal sequence number stored for each transaction line according to the line item’s position in the sublist. This is the value expected by the nlobjSublist methods

setLineItemValue(name, linenum, value)

and

getLineItemValue(group, fldnam, linenum)

. Unlike Line ID, the Line Sequence Number is related to the line item’s position in the sublist and can change if the line item's position changes. For example, if you want to add a new item to an existing sales order, you would not specify the Line ID. If you leave it unmapped, it will append your lines to the existing document. However, the Line Sequence Number would be used to determine the position of the new line item in the sublist. In the context of an advanced PDF template, you might use

${item.linesequencenumber}

to reference the Line Sequence Number. However, some users have reported that this returns blank, possibly due to the context of the item list. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
