We all know we can't use CSV import for updating transaction forms on historical Sales Order. Thus, I'm using the console, which works, but only 1 record id at a time. How can I push the full JSON? Something like: nlapiSubmitField('salesorder', 52440634, 'customform', 293), nlapiSubmitField('salesorder', 52440934, 'customform', 293), nlapiSubmitField('salesorder', 52441334, 'customform', 293), nlapiSubmitField('salesorder', 52441337, 'customform', 293) ...

put all sales order internal id in an array? or get them through a search and loop through it?

Actually, it worked. I had to remove the comma, but It was falling due to another unrelated script. Thanks

Just noticed the comma as well.

for others looking, I just wanted to mention you can set the form via workflow. See this answer/discussion on Reddit: https://www.reddit.com/r/Netsuite/comments/qzv03r/comment/hloolnt/
