  Backflush

Use

At planned order reporting points, and as required, you can go to the backflush transaction using fast entry backflush, in order to supplement the backflush data.

Prerequisites

To display the backflush data in the detail area, use a detail profile, assigned to the detail screen BACKFL. For more information about the profiles, see Preparatory Measures . You select the detail profile in the User Settings.

You insert the components Production Backflush .

Backflushing takes place at reporting points:

  • For line orientated production, you have defined reporting points for a line segment, a line network, in the line design within Integrated Product and Process Engineering , and assigned reporting point types to them.Using the reporting point types, you can determine how the backflush should take place.

    Assigning Action Points

    Defining Reporting Point Types

  • · For shop-floor-orientated production, you have maintained reporting points in the Mode ,or modes for the activity in the process structure within Integrated Product and Process Engineering . If a mode of an activity has a reporting point, then the other modes must also have a reporting point assigned to them. The reporting point type must be the same for all modes within an activity, and for this reason it is maintained from the activity.

You have created a backflush profile. (Refer to Define and Set Default Values for Profiles ).

For further information about the prerequisites, see Backflush Proceerdure .

Features

In planned order management , the functions of the production backflush are listed on the Backflush tab page .

In the left area of the screen the following data for the selected planned order is listed:

  • all reporting points to be passed through

  • the backflush quantity (the maximum possible quantity which can be backflushed at that particular reporting point).

  • yield and scrap (previously backflushed quantities)

  • indicator Active Mode

    If alternative resources are available for an activity, the indicator is displayed using the Active Mode , where (with which mode) the activity is regularly to be executed. A backflush can not only be executed with the planned mode, but also with an alternative mode. The differentiation of the mode during backflush, works using the reporting point.

    Note Note

    If you backflush at a reporting point for a resource which is not indicated as being the active mode, the system sets that mode to active.

    End of the note.

In the right area of the screen , you can enter backflush data for one of the selected reporting points in the left screen area:

  • Backflush quantity

    Enter the quantity that you want to backflush.

    Caution Caution

    When using the Rapid Planning Matrix(RPM), you can only backflush the total order quantity (generally 1). You cannot backflush partial quantities.

    End of the caution.

    Note Note

    You can also reverse a backflush. The cancellation is always a posting with a reversed movement direction. This means you enter the quantity, which you want to cancel with a negative sign.

    End of the note.

  • Quantity indicator (yield or scrap)

  • Cause of the scrap, which was incurred during production

    You specify a cause, if you have selected the scrap quantity indicator. Causes could be, for example, machine damage, operator’s failure, or a defect material.

    Note Note

    The cause indicator is specified in Customizing for the Advanced Planner and Optimizer (SAP APO), found under Start of the navigation path Supply Chain Planning Next navigation step Production Planning and Detail Scheduling (PP/DS) Next navigation step Production Backflush Next navigation step SetProfile. End of the navigation path

    End of the note.

You can backflush immediately ( Post Immediately ), or goto the backflush transaction ( Supplement Backflush ). The order data, and the previously entered backflush data are adopted at this point.

When the backflush is complete, the system updates the relevant order in the order overview.

Caution Caution

If you set the status “final backflush”, the system cannot update the display in the order overview immediately. The cause of this, is that the indicator can only be set when all of the following processes in the SAP R/3 system are posted. When posting asynchronous goods movements, this is dependent on the frequency, with which these goods movements are posted in the SAP R/3 system. Synchronous goods movementsare update immediately. This includes the goods receipts and the materials for which you set the Synchron.post GI indicator in the product master in APO.

As the process for updating the backflush data runs independently to the updating of the display, you must manually update the order overview after a backflush ( ).

End of the caution.
