    Dear

    There are lot good threads and wiki abailable for this generic topic .

    These are diffrences between REM/Discreate/ and Process manufacturing.

    REM:

    Production is based on the planned orders.

    Planning and manufacturing is based on period wise.

    Normally single products being manufactured for a longer period of time.

    Normally production are carried out on a single production line (repetitively).

    Product costing and settlement is done through product cost collector.

    Planned orders are known as Run schedule quantities. Means quantity which is being manufactured in a certain period.

    Planned orders are sufficient to carry out production at shop floor area.

    Master data includes production version, product cost collector and rate routing.

    Materials will be issued anonymously to production lines means without reference to planned orders.

    Discreate:

    Production based on the production orders

    Planning and manufacturing depends on production orders.

    Products changed frequently.

    Production is carried out on different production lines (scattered- discrete).

    Product costing and settlement is done through production orders.

    Planned orders are stock type later converted into production orders.

    Production orders are required.

    Production version and product cost collector are not mandatory.

    Materials will be issued always with reference to production orders.

    Master Data includes Routings and BOMs.

    PROCESS:

    1) Batch Oriented process manufacturing.

    2) Process order based manufacturing.you copy the process described in a master recipe and adjust it to the actual production run.

    3) It is primarily designed for the chemical, pharmaceutical, food and beverage industries as well as the batch-oriented electronics industry.

    4)The integrated planning of production, waste disposal, and transport activities within a plant.

    5) Master Data includes Master Recipes and resources.

    6) Process Management:In this area, you coordinate the communication between PP-PI and process control during the execution of a process order.

    Best will be refer SAP help material .Appereciate if you carry out forum searh on the same .

    Regards

    Dear,

    PP(discrete ) As the name describes this is used where one work center is used for many orders and we need to schedule the orders depending on the requirement. Best example is in a engineering industry lathe can be used for many purpose, hence one order may be for a chair or other order may be for a table, in both cases say the leg is manufactured in lathe. Hence both order is routed through lathe. Both end product is different. For implementu2026it is not complicated, but not as simple as Repetitive manufacturing.

    PP-PI  This is used mainly in a process industry where in process is usually batch managed and we need to use PI sheet (operates enters the production and consumption, shift in charge to approve the qty and GR/GI happens in background), and the batch has to be authorized before confirming the product. This is usually in a pharma industry. For implementu2026it is complicated if PI sheet is involved

    Repetitive manufacturing This is used in a industry where product is continues and only one product is produced for long duration. No much controls are required. For implementu2026it is simple

    I hope all there questions are answerd, if not come back.
