Dfference between insert line and select newline

In NetSuite scripting, both insertLine and selectNewLine are used to interact with sublists, but they serve different purposes. Here’s a comparison:

1. selectNewLine

• Purpose: Prepares a new line in a sublist to set values for new entries.
• Usage: When you want to add a new entry to a sublist by editing fields directly.
• Example:

record.selectNewLine({
    sublistId: 'item'
});

• Context: Typically used when adding a new item to a sublist (e.g., Sales Order lines, Sales Team).
• Process: You use selectNewLine() to start editing a new line, set values for fields with setCurrentSublistValue(), and then call commitLine() to save the changes.

2. insertLine

• Purpose: Inserts a new line at a specific index in a sublist.
• Usage: When you need to add a line at a specific position in a sublist, not necessarily at the end.
• Example:

record.insertLine({
    sublistId: 'item',
    line: 1
});

• Context: Typically used when the sequence of the sublist matters, and you need to add a line at a specific position (e.g., inserting an item line at a particular place in an existing list).
• Process: You specify the exact line number where you want the new line to be added. After inserting, you can set values directly to that line.

Summary of Differences:

• Functionality:
• selectNewLine() starts a new line at the end of the sublist and prepares it for data entry.
• insertLine() inserts a new line at a specified index within the sublist.
• When to Use:
• Use selectNewLine() when simply adding a new entry at the end of a list.
• Use insertLine() when the order of entries is critical, and you need to add a line at a particular spot.

Common Scenario:

selectNewLine() is more commonly used when adding entries since it simplifies adding lines at the end, while insertLine() is used less frequently, often when specific positioning is required.
