This is a project design suggestion. I have outlined a new project scenario below and would appreciate your best suggestions to start designing it:
Invoices in PDF format from multiple suppliers, each with different formats.
Reading the invoices using Document Understanding or another method you suggest. The data includes( PO Number, Date, VAT, Company Name, Amount, and Reference Number.)
An Excel file containing a data table containing the following columns(export from the system): PO Number, Date, VAT, Company Name, Amount, and Reference Number.
Compare the data extracted from the PDF files with the corresponding data in the Excel file.
5-send email for data not matching and incorrect
For this, DU will output the PDF details. Compare it with step 3 excel file data using LINQ/Filter Datatable/or any way fits at the place.
For this prefer SMTP send mail activity as it’s it’s faster and don’t require outlook installed. Other ways would be Office 365 Send Mail and Outlook Send Email
