SAP Order Data Export Help

I need a seasoned SAP consultant who can jump on a short, 2-to-3-hour screen-share session with me and show, step by step, how to pull the accounting-focused order data I’m after and get it out of the system in a portable file.

Context
• My system records purchase-order activity in an accounting back-end rather than the usual MM, SRM, or Ariba paths, so you’ll need to be comfortable navigating FI/CO tables, custom Z-tables, or any cross-module links that might store the numbers.
• The main objective is to isolate all fields tied to these orders (header and line items, posting details, values, partner data, timestamps, etc.) and make sure nothing is missed.

What I’d like from you during the call
1. Identify the tables, transactions, or CDS views that actually hold the accounting order information.
2. Walk me through extracting the data—whether that means SE16N, SQVI, SAP Query, or a quick ABAP report.
3. Ensure the export works end-to-end (I’m flexible on CSV, Excel, or similar as long as I can open it locally).
4. Leave me with clear notes or a small script so I can repeat the process afterward without you.

I already have access to the system and can share my screen; you only need a stable connection and your SAP know-how. If you’re confident you can zero in on accounting-side order data quickly, let’s set up a time and get it done.
