Coding liquidity forecast - big problem - How to?

28 Views

Hello coders,

I have the honor to code a liquidity forecast. Problem: this theme is bascally a SD theme, but I am FI. Nevertheless I have to code it - somehow, but I do not know how. Does anybody accidentally coded something like this? functionality: selection screen with document type, document number and a start date. Based on the start date the incoming payments are forecasted for 12 periods/months. To be considered: document flow, SD invoices, status of FI documents - payed or not.

With a little help from a colleague I nearly solved the forecast for order-related invoices with or without billing plan.

But now I have to implement it for delivery-related billing documents. It's all Greek to me. A SD consultant explained me the logic only rudimentary, but not in which tables or connections I can find the information, or which document flow I have to read (anyhow) and so on.

Does somebody coded something like this and can give me some advice how to? SAP function modules to read and anaylse it?

Thanks.
