Backflush - Understanding / setting

Dear All,

We are in the process of implementing backflush option for bulk material production consumption.

I was going thro the SAP help & some of the threads here in SCM - PP.

I could find lot of information, but I am totally lost because our team does not have any exp in implementing this.

In this situation, <u><b>may I ask the help of Experts to shed some light on this?</b></u>

<b>1. Where to start

2. What are the setting required

3. Which option to follow for backflush & pros and cons of each,</b>

Your support is greatly appreciated

Thanks in advance

Raj

    Hi,

    First should I know on which scenario are you working?(Discrete/REM)

    If discrete,you can set backflush indicators either material master or work center.If you want backflush indicators to be set in material master master, in MRP2 view in

    'backflush select '1'

    1 Always backflush

    2 Work center decides whether to backflush.

    If you want backflush indicators to be set in work center,in MRP2 view in

    'backflush select '2'

    These are simple settings.

    For storage location determination,there is also one big logic.

    The issue storage location must already have been determined for the pull list

    by MRP (because the system does not take dependent requirements into account

    without an entry for an issue storage location): Here, the system first searches for

    the issue storage location in the BOM item of the component (Production storage

    location field). If no storage location is entered in the BOM item, the MRP group

    of the assembly determines whether the issue storage location from the material

    master record of the component or from the production version of the assembly

    is to be used (strategy for production storage location selection). This strategy

    is defined per MRP group in Customizing for Repetitive Manufacturing in work

    step Define Storage Location and Supply Area Determination in BOM Explosion :

    Storage location = 1: The system adopts the production storage location in the

    material master of the components as the issue storage location. Storage location

    selection = 2: The proposed issue storage location in the production version (of

    the assembly or finished product produced) is used as the issue storage location

    for all components. If a proposed issue storage location has not been entered in the

    production version, the system uses the assembly's receiving storage location as

    the issue storage location for all components. You can define the receiving storage

    location via the receiving storage location field in the production version of the

    assembly, or via the issue storage location field in the material master record of the

    assembly. If neither of these entries has been made, you can define the receiving

    storage location at backflush in REM. This will then be used as the issue storage

    location for the components. You should use indicator 2 when all components are

    stored together in one storage location close to the production line where they are

    required. Storage selection = 3 and Storage selection = 4: The same procedure

    applies. If no MRP group has been entered for the assembly/finished product, the

    system reads the entry in the Production storage location field from the material

    master of the component as the issue storage location for all componen.

    But generally storage location is maintained in material master.

    Hope this help you.

    Regards,

    Shailendra

      Dear Shailendra,

      Sorry for the late reply. I was on vocation to India.

      Anyway your reply is very useful and informative. I will start another thread, if I encounter any issue during the course of setup and implementation.

      Is it possible to provide your personal e-mail id - in case of any criticality I would like to contact you directly.

      Thanks again for the detailed reply.

      Raj.

    Are you talking about SAP bulk material ie. is it the materials which is available

    directly at the work center (for example, washers or grease)?.
