Configuration of PR in SAP MM.

1. Define Number Ranges for Purchase Requisition:

Path	SPRO> MM > Purchasing > Purchase Requisition > Define Number Ranges for Purchase Requisition

Here we need to define a number range for the PR document type.

2. Define Document Types for Purchase Requisition:

Path	SPRO > MM > Purchasing > Purchase Requisition > Define Document Types for Purchase Requisition

Define the document type for PR and assign the number range you created in the previous step.

3. Define Screen Layout at Document Level:

Path	SPRO > MM > Purchasing > Purchase Requisition > Define Screen Layout at Document Level

Define the screen layout at the document level by specifying which fields are mandatory, optional or hidden. ( we can change the field settings using the field selection key ) .

• Processing time

Path	SPRO > MM > Purchasing > Purchase Requisition > Processing time

The processing time is the time required by the buyer to convert a requisition into a purchase order The processing time is taken into account during the scheduling process for externally procured materials within the framework of materials planning and control.

• Define Release Procedure for Purchase Requisition:

Path	SPRO > MM > Purchasing > Purchase Requisition > Release procedure (Set Up Procedure Without Classification)

Here you can define the release strategy for PR by specifying the release codes, release group and release strategy.

Creation of purchase Requisition (manually – ME51N)

• By using master data – We will maintain the material master , source list and the purchase info record and then will create the purchase requisition .

Path	Logistics ⇒ Materials Management ⇒ Purchasing ⇒ Purchasing Requisition ⇒ Create
T-code	ME51N

PR creation without master data ( with 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.
• 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.
• With multiple account assignment, you can distribute the costs for one purchase order item among several cost centers
• 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 sub quantities. The system automatically distributes the requested quantity in equal parts to the existing account assignment items. If you change the requested total 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.

Valuation price in purchase requisition :

When you create a purchase requisition item for valuated material, the valuation price is pulled from the material master record. For non-valuated material or material without a master record, the creator must manually enter the valuation price. This valuation price can be used for a value-related release procedure. The release can refer to the value of the individual item or to the total value of the requisition.

Status and Creation Indicator

• If we want to trace whether our purchase requisition item has been processed, evaluate the processing status of the purchase requisition item.
• we can see the processing status on the Status tab page in the item detail area. The processing status provides information about whether the item has been ordered, not ordered or requested, or whether the item has been converted into an outline agreement.
• The Status tab lists the purchase order history of referenced purchasing documents(created with reference to this purchase requisition item). You can obtain information about previously posted goods receipts and invoices.
• If you are interested to see how the purchase requisition was created in the system, manually or automatically (for example, through materials planning).Go to  the item detail on the Contact person tab, the creation indicator will provide this information
