There isn't much information about this procedure and the official website doesn't help at all. What I can recommend is taking advantage of the built-in Help feature. If you have Pastel Partner opened, press F1 or go to Help > Contents. Use words like centralize or statement to narrow down search queries to find results faster. Additionally, look in the installation folder of Pastel Partner to find details about user guides in PDF format. You will need Adobe Reader in order to open those files.
