How do I resolve "Duplicate line number (No) Line 1 is duplicated"?


After importing a transaction it returns with an error file that contains Duplicate line number (No) Line 1 is duplicated.

  • Change the line number to be a unique value


Note​: Each Doc code must have a unique line number for each item, example 1, 2, 3, 4, a, b, c etc. are all unique values
