Hi Raju,
Requirements classes control the creation of planned independent requirements or sales orders and customer requirements. The following is determined via the requirements type:
consumption of independent requirements and customer requirements
how warehouse stock is taken into account (net or gross requirements planning)
inventory management and cost consumption (make-to-order or make-to-stock)
if the planned order can be released (planning without final assembly)
requirements distribution (configuation)
The control parameters for the requirements class are stipulated in demand management and cannot be changed.
The requirements type is a language-dependent key that can be given a short text. When maintaining planned independent requirements, only the requirements type is displayed.
A requirements class can be allocated several requirements types.
Some Standard Requirement Types for different strategies as follows:
