besides preforming a transaction search with the filter ["customgl","is","T"] , what are other ways to detect if a transaction has suiteGL or a custom plugin script applied to it within suitescript? are you directly able to access the GL impact of a transaction within suitescript 2.x, not using suiteGL or a custom plugin? Not opposed to just writing a custom plugin, I just like the capabilities of map/reduce

I'm not sure if this is an option for you or it it's exactly what you're looking for, but it is possible to get a transaction's GL impact via SuiteQL. There's a query in this blog post - https://timdietrich.me/blog/netsuite-suiteql-journal-entries-gl-impact/ - that shows how to do it. I hope that helps.

Can you invoke a SuiteQL query within suitescript? Is this completely separate from using the N/query module? I think I need to learn more about SuiteQL and how you can use it within a custom busines process
