You can create purchasing info records for different procurement types as follows: 

Standard, Subcontracting, Pipeline, Consignment You use this component if you wish to store information on a vendor and a material as master data at purchasing organization or plant level. 

Standard
-------------
A standard info record contains information for standard purchase orders. 
The info records can be created for materials and services with and without master records.

Subcontracting
-------------------
A subcontractor info record contains ordering information for subcontract orders. 
For example, if you subcontract the assembly of a component, the subcontractor info record would include the vendor's 
(subcontractor's) price for assembling the component.

Pipeline
-------------
A pipeline info record contains information on a vendor's commodity that is supplied through a pipeline or pipes 
(oil or water) or by similar means (electricity through the mains). 
The info record contains the vendor's price for the consumption of such commodities by the buyer 
("pipeline withdrawals"). You can store withdrawal/usage prices for different validity periods.

Consignment
-----------------
A consignment info record contains information on a material that vendors keep available at their own cost on the orderer's premises. 
The info record contains the vendor's price for withdrawals by the orderer from consignment stock. 
As in the case of the pipeline info record, you can store prices for different validity periods.
