A purchase requisition is a request or instruction to Purchasing to procure a certain quantity of a material or a service so that it is available at a certain point in time.
A purchase requisition consists of a number of items, for each of which a procurement type is defined. The following procurement types exist:
An item of a requisition contains the quantity and delivery date of the material to be supplied or the quantity of the service to be performed.
For items to be supplied by subcontractors, you can specify the necessary input materials or components that are to be provided to the subcontractor for assembly or processing in respect of each delivery date stipulated.
An item of the procurement type
contains a set of service specifications. The latter can be hierarchically structured. The summary view of such a hierarchical structure is referred to as an outline. The outline comprises a number of levels, each representing a level of the service hierarchy. The ordered quantity and date of performance are set out in service lines, representing individual jobs or activities. Value limits are specified instead of service lines for services or work that initially cannot be specified precisely.
If services covered by an already existing contract are requested, the requisition item can contain a value limit relating to the contract in question.
Costs can be apportioned among various Controlling objects via the account assignment.
A purchase requisition can be fulfilled through purchase orders or longer-term purchase agreements.
It is an internal document: it is not used outside the enterprise.
