DDMRP Warning

This module adds a configurable warning system on top of DDMRP stock buffers. You create warning definitions (description, severity, an optional domain to limit which buffers they apply to, and a small Python expression evaluated against each buffer). Four example definitions are installed: spike horizon smaller than DLT (high), quantity multiple bigger than MOQ (medium), minimum procure batch bigger than MOQ (medium) and ADU is zero (low).

Definitions are managed under the DDMRP configuration menu (Warning Definitions), where DDMRP managers can create, edit and archive them; buffer maintainers can only read them. Archiving a definition deletes its existing warnings.

On each stock buffer form a new Warnings tab lists the warnings raised for that buffer, colour-coded by severity, with a Refresh Warnings button. A daily scheduled job recalculates warnings for all buffers, and a With Warnings filter is added to the buffer search. A DDMRP Warnings report menu lists all raised warnings with product, location, severity and company, and can be grouped by buffer, severity or definition.

Warnings are created when the expression returns true and removed when it returns false or the definition no longer applies. Deactivating a buffer also removes its warnings. Warning items are restricted per company.
