The Purchase Blanket Agreement Module introduces the following concepts:

## Purchase Blanket Agreement

The Purchase Blanket Agreement is used to manage the agreements between the Company <company:model-company.company> and its suppliers.

Each agreement progresses through multiple states: ‘draft’ as default when created, ‘running’ when operational then ‘done’ or ‘cancelled’ as final step. A warning is displayed if the user tries to close an agreement with remaining quantities.

An agreement is identified by a unique number that is generated automatically from the configured Sequence and may also have other general information such a validity period, a description, or a reference provided by the supplier.

Each agreement is made up from one or more lines. Each line on an agreement provides information about which Product <product:concept-product>, the price, the agreed quantity, the processed quantity and the remaining quantity.
