When using the 'Anchor Base' method, what is necessary for correctly identifying data within a PDF?

The 'Anchor Base' method relies on using specific labels or identifiers within the text of a document to locate and extract relevant data. Constant labels act as reference points that help the RPA tool understand where to look for the necessary information in the PDF. This method is particularly useful because it allows the automation to pinpoint data even when the layout of the document may vary, as long as the labels remain consistent.

While aspects such as fixed widths might improve consistency, they are not essential for the anchor method to work. Similarly, having the same header across all documents or converting a PDF into text format could be beneficial in specific scenarios, but they do not address the fundamental requirement of having stable, recognizable labels to function effectively. Therefore, having constant labels as anchors is crucial for successfully identifying and extracting data from a PDF using this method.
