It is necessary to use secondary lines explicitly when a row begins on one page and ends on the next, or when learning an unmapped secondary line leads to an extraction. Refer to the following cases to understand more about these circumstances.
- Case 1: A row begins on one page and ends on the next
- If a table row begins on one page and ends on the next page, you must use the Learn as Secondary Lines function in lines learning mode to train missing secondary lines.
- Case 2: Learning of unmapped secondary lines leads to unwanted extraction
- Sometime the engine extracts data from secondary lines when its not a requirement for your project. In this case, not learning these secondary lines prevents unnecessary extractions.
