You can find the logic in the Lawson Documentation. Search for the form number in the docs.

PZ,

k-rock is referring to the Technical Text (broken out by system code). However, if you are looking to reverse engineer the AP221 program, you will have to look (and be able to make sense of) the COBOL code.

Thank you both for the feedback. I'm not looking to reverse engineer the report, just trying to figure out how it pulls the duplicates. Can you give me a little more direction as to where I can find the documentation/technical text. Can this be access directly from the portal or is it online somewhere? I've just started using this system so I'm not familiar with the navigation yet. Our IT department provided me with a few data dictionaires in PDF format but I didn't receive any hits when searching for AP221.

Thanks again.

technical text is accessed from support.lawson.com or the ERD section of this site.

In the case of AP221, the technical text is, uh, lacking. You'd have to look at the COBOL itself. The way it detects duplicates is by looking at the company, vendor, invoice amount, and the fields you select on the 'Sort' tab. In other words, anything besides invoice number that makes it look like it might be a duplicate.
