Production version and Planned order question

Hi Gurus, I am trying to udnerstand two different topic here

1. why is a production version mandatory for repetitive manufacturing scenario and why not mandatory for discrete?

I was thinking that production version is mandatory for discrete and not mandatory for repetitive. The reaosn that I came to that conclusion is..

If I have a material that has 3 alternate boms and production order should display particular bom, then I need to maintain production versions ? at the same time if I have a material that is produced in different ways depending on the lot size, then I need to create different production versions..right???

In repetitve manufacturing, you always have one bom, one routing as the process will not change. so there is no need of creating multiple production versions. system will pick the routing and bom automaticaly (as there is only one option - one combination of bom and routing).

where is my thinking going wrong/incorrect?

2. why cant I do repetive manufacturing with production order? what advantage planned order offers to me in repetitive manu scenario over production order?

Thanx

    IN production Version, For rem Scenario, Bottle neck Work center has to enter In the production Line, This Bottleneck work center is used to calculate capacity & scheduling for the work center, thets the reason, Production version is required for REM scenario

    when it comes to production order, then It will be come under order Based, REM scenario is mainly for period based, If client doesn't want to track the production cost based on the lot.

    Dear SCM,

    For difference between REM and discrete, you can perfrom an search you can get many threads with clear explanation

    Coming to alternative BOM's and PV's

    If we have alternative BOM's then we mainatin PV's

    Check my reply from this links

    [Using customer to determine what BOM to use in Production order (tx:CO41);

    [Alternative BOM selection by Production Version;

    Regards

      Madhu,

      Thanks for the reply.

      lets take the same example what you gave.

      we can also do production using repetitive manufacturing for the example you said. right?? so if I opt for repetive manufacturing for the example you said, why do I need to create production version? why is it mandatory to create production version for the same scenario if I go by repetitive way...

      I hope you got my question now?

    Dear SCM0925,

    __Why Production version is a master data in REM?__

    1.Product Cost collectors are the cost collecting object in a REM scenario, for creating product cost collector we need a

    production version which is defined as the controlling level(however there are other controlling level like BOM & routing ,

    Production Plant/Planning Plant.).

    2.There are certain other parameters related to Distribution key, production line which is present in the productioon version,so

    Production version is a master data in a REM scenario.

    Advantage of Planned orders than Production Order:

    1.There is no status processing required for a planned order,where as in a production order you have to release it,then GI to

    order, confirmation,then TECO etc.

    2.In a Discrete scenario,You can confirm only with respect to a production order,but in REM you can do the production

    confirmation even without a planned order.

    3.Even in REM if there is one BOM and different processing method,we combine it using different production version or if there

    are different BOM for different processing method we need to create multiple production version.

    Check and revert

      Thanks Mangalraj. First question is cleared.

      regarding 2nd question..

      can you help me understand functianlity wise, why cant we do a production order for repetitive manufacturing? howz planned order helping repetitive manufacturing scenario?

      for example

      when mrp generates planned orders, it generates for cetain quantity, say 500 pc. so still its a quantity based production right? how is it different to production order based?

      planned order quantity after mrp is 500 pc - now you run repetitive manufacturing based on planned order

      convert 500 pc planned order to 500 pc production order, you do discrete..so what is the diference?

      Thx
