SAP Recommended Procedure – Procurement
Manual Reorder Point Planning
The
main function of manual reorder point planning is to guarantee material
availability on time that is to be procured or produced the required
quantities, both for regular consumption and for plant maintenance functions.
This process involves the monitoring of stocks and, in particular, the
automatic creation of procurement proposals for purchasing and production.
In MyCompany's this process is specifically used for planning the availability of the material
which is not a part of BOM.
MRP
for material which are part of BOM please refer PP (Production Planning BP).
Some
materials such as Machine and Spares and Chemicals would be used for this kind
of planning while some will not be a part. This will be finalized during the
realization phase with the co-ordination of materials manager.
Materials
will be planned on the basis of re-order point where MRP will check the
requirements for each material that is to be planned where stocks fall below
the re-order point set for the material. A requirement is then generated
automatically through the MRP run in the system in the form of plan orders and
converted into a purchase requisition by the MRP Controller.
Reorder
point will need to be defined in the material master record of the corresponding
materials. MRP Controllers of relevant plants will run MRP on periodic basis
(preferably on a fortnightly basis by MRP Controller). However, for urgent
requirement of any material, MRP run can be performed immediately for that
particular item. The purchase requisition created can then be picked up by the
purchasing department upon daily monitoring of the records.
Purchase Requisition
The
procurement process commences with the recognition of stock shortage. This
determination of requirements is called a purchase requisition (PR). 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
it is also served as a notification of requirements of materials and/or
external services and keep track of such requirements.
Requisitions
can be created either directly or generated from the material requirement
planning (MRP) in the system. "Directly" means that requester to
enter a purchase requisition manually for the items he/she needed in the system
For
raising purchase requisitions the following PR types will be used, with
internal number ranges generated as defined.
