This Saved Search gives me duplicates, even when Main Line = T... Any idea why?

var journalentrySearchObj = search.create({
   type: "journalentry",
   filters:
   [
      ["type","anyof","Journal"], 
      "AND", 
      ["mainline","is","T"]
   ],
   columns:
   [
      search.createColumn({name: "tranid", label: "Document Number"}),
      search.createColumn({name: "memomain", label: "Memo (Main)"}),
      search.createColumn({name: "trandate", label: "Date"})
   ]
});

Please try to add specific GL account in criteria.

Unlike with most (all?) other transactions, every line of a journal is considered "main line." if you're just wanting to get a single line per JE, usually adding in Line ID=0 works.

Oh, interesting about being considered Main

@Edgar Valdés You are Welcome.

The reason journals doesn't apply for main line is because there is no account on the "head" of the transaction as it is for other transactions

Makes sense @Jesper M Thanks!
