Introduction [edit]
As you know SAP implementation is nothing but re-engineering of existing business
processes into SAP R/3. All most each and every industry specific solution has been taken
under the umbrella of SAP R/3. Each and every modules of SAP is integrated with other for
the common purpose of sharing the data and information already available into the system. In
addition to the already available data in the system, during implementation phase of SAP a
lot of master data is migrated from legacy system to SAP.
Information related to these master data is being used in almost every modules of SAP. For
MM module, Vendor Master and Material Master are being migrated to the SAP as the
Master Data.
In addition to this, the following purchasing master data is also maintained towards
optimization of purchasing which is being used and re-used again and again for source
determination:

Source Determination [edit]
So before you get into the purchasing transaction you have sufficient purchasing data. With Basics of Excel VBA: Cell Navigation

source through the requesting and processing quotations. If your organization is not into the
SAP then it can be a very time consuming and repetitive activities, but if it is into SAP, then it
is only one time activity and maximum information related to vendor and material can be used
again and again.
As a rule, a standard productive system which procures the material internally and externally
will have a large number of vendors and outline purchase agreements as internal and external
sources of supply. So if your organization has more than one source of supply for a certain
material or service, then buyer have to find out the most suitable source out of available
sources. To meet this requirement and to help the buyer the SAP provides the source
determination facility to find the most suitable source for a certain requirement from the large
volume of data that is available, i.e. it suggests a suitable outline agreement or
vendor/supplying plant for ordering purposes.
Possible Sources of Supply [edit]
In standard SAP all the available sources of supply has been categorized as follows: Some of
the organization may make the use of all the below mentioned categories or they may
choose any one or more as per their business requirements;
Outline agreement
Info record
Supplying Plant
Quota arrangement
Source list

Order of sources for Source Determination [edit]
Since you have more than one category available in the system and each category may have
a large number of sources available under it so there is a strong need to priorities all these
categories based on the order system should look for these.
The standard SAP system determines the possible source of supply of a requested material
in the following order:
Quota arrangement [edit]
The system first determines whether a quota arrangement within whose validity period the
delivery date in the requisition falls exists for the material. If a quota arrangement exists, the
system determines the vendor from whom the material is to be procured according to the
quotas assigned to the vendors and then suggests the source.
If no source can be determined on the basis of Quota arrangement then the system checks
the source list.
Source list [edit]
The system determines whether an entry in the source list within whose validity period the
delivery date of the requisition falls exists for the material. The source in question may be a
fixed vendor or an outline agreement (contract or scheduling agreement). If the source list
contains a unique source, the requisition is assigned to that source. If several sources are
found, a box appears for selection purposes. Buyer can choose one out of it. If no source
could be determined from source list, then the system checks all the existing outline
agreements and info records.
Outline agreement and info record [edit]
The system searches for contracts, scheduling agreements, and info records for the material
and suggests these. If several outline agreements (contracts, scheduling agreements) and
info records exist for a certain requirement, all possible sources are offered for selection in a
box. Buyer can choose one out of it.
When an info record is found, the following two additional checks are carried out:
For supply region
For regular vendor
Source Determination in the Background [edit]
During source determination process in the background, the system checks all the available
source of supply in the same order as mentioned above. If the system finds more than one
source of supply out of quota arrangement or source list, then system determine a unique
source out of these to enable a purchase order to subsequently be generated automatically. If
several sources are found at outline agreement and info record level then system gives the
outline agreement precedence over the info record in order to arrive at a unique source. If two
outline agreements are found, the system checks whether one of them is with a regular
vendor. If so, this agreement is assigned as the unique source. If during the above process
system does not find and assigned a suitable source of supply to the requirement (automatic
purchase order), then you must assigned the source manually.
