SAP Purchase Requisition - 2
In this article we will discuss the structure of the purchase requisition. By highlighting common features and differences between a purchase requisition and a purchase order, such as the following:
- Missing a “proper ” document header in the purchase requisition • Specifying the vendor at item level of the purchase requisition is possible, but not compulsory
- Document overview in transactions ME21N and ME51N
In the transactions for creating, changing or displaying a purchase requisition (ME51N, ME52N, ME53N), there are single-screen transactions, just as in the purchase order. The division into different screen areas (header data, item overview, item details, document overview) and the operation correspond with the purchase order transaction.

Entering the Account Assignment
If you want to request materials or services directly for an account assignment object, for example, for your cost center or for an asset, you must specify in the item overview the corresponding account assignment category. This means that you have to enter additional account assignment data in the item detail on the Account assignment tab.
If you have the single account assignment screen displayed on the Account assignment tab, you can use Multiple account assignment to switch to the multiple account assignment screen. On the multiple account assignment screen, choose Single account assignment to switch to the single account assignment screen. The SAP R/3 system stores your last setting. On the multiple account assignment screen, you can also create single account assignments.
With multiple account assignment, you can distribute the costs for one purchase order item among several cost centers, for example. In this case, the created account assignment data represents individual account assignment items. With multiple account assignment for an item, you must decide whether the value of the item is to be distributed on a quantity basis or as a percentage (for example, 10 pieces or 10% of the purchase order value to cost center 1000).

If there are partial invoices, you can choose whether
- the partial invoice amount is distributed proportionally to the account assignment items
- the partial invoice amount is distributed to the account assignment items one after the other
The partial invoice indicator can also be derived automatically from the account assignment category if a partial invoice indicator is specified in Customizing for the account assignment category. For items with multiple account assignments, the system automatically sets the GR non-valuated indicator.
If you want to distribute the quantity in a purchase requisition item with account assignment to the different account assignment items, you just need to enter the account assignments, but not the quantity. The system automatically distributes the requested quantity proportionally to the existing account assignment items. If you change the requested quantity in the item overview, the quantity is adjusted in the relevant account assignment items. As soon as you change the quantity or percentage of the account assignment item, the system can no longer execute an automatic distribution.

Example of an automatic account assignment distribution: You have requested 90 office chairs and assigned them equally to three cost centers. However, because you require 120 office chairs, you change the requested quantity in the item overview. The system then automatically changes the distribution so that 40 office chairs are assigned to each cost center.
