Creating the Backflush

Use

The interface for entering the backflush data is in the SAP APO system.

Prerequisites

  • In Customizing for the APO System, under Start of the navigation path Production Backflush Next navigation step Set Profile, End of the navigation path you have created or selected a profile. Refer to Define and Set Default Values for Profiles .

  • In Customizing for the SAP APO system, under Start of the navigation path Production Backflush Next navigation step Specify Reason for Variances End of the navigation path , you must define possible reasons for variations or for scrap during the production backflush.However, the specification of the scrap reason is not mandatory and is only used for documenting the backflush.

Features

  • You enter the backflush data depending on the type of production.

  • You can reverse a backflush by creating another backflush with negative quantities. In general, this is a document-neutral reversal. The status of the order does not change. For further information, see Canceling the Backflush

  • In the SAP APO system, you can backflush components and production activities and enter variances to the planned quantities for components and production activities.

  • In the SAP DI system, you can use a separate variance posting and enter over-consumption or under-consumption of components and production activities independent of the order, directly in the product cost collector. See: Enter Variances .

Activities

  1. In the APO system, choose Start of the navigation path Advanced Planning and Optimization Next navigation step Production Planning Next navigation step Manufacturing Execution Next navigation step Production Backflush for Repetitive Manufacturing Next navigation step Create Production Backflush for Repetitive Manufacturing End of the navigation path (transaction PPC1).

  2. Choose the appropriate tab page depending on your production type and enter an order, a product or a sales order.

  3. Enter a reporting point.

    Note Note

    Note that in the case of line-based production, the reporting point structure is always transferred from the current production data structure. If you work with shop-floor-oriented repetitive manufacturing, the reporting point structure will be chosen that was valid at the time the order was created.

    Note, furthermore, that the reporting point structure is always determined with the first backflush.

    For further information see the documentation about the APO master data, in particular Displaying the Production Data Structure .

    End of the note.

  4. If you have maintained the Final confirmation / Partial confirmation field in your profile, choose one of the options listed in the input help.

    Partial confirmation : Further backflushes are expected at the reporting point.

    Final confirmation irrespective of quantity : No further backflushes are expected at the reporting point.

    Final confirmation dependent on backflushed quantity: The system decides. That is, if the total expected quantity was backflushed, the system posts a final confirmation; if a smaller quantity as that expected was backflushed, a partial confirmation is posted.

    Reset in Backflush Status: You can reset the backflush status for this reporting point. To do this, enter the reporting point with the quantity that has already been backflushed for the reporting point as a negative quantity. You can reset the status of the associated activity as well as the status of the order.

    Note Note

    Note that the backflush status of the order is only reset if:

    • the backflushes for all reporting points have been reset and

    • the subsequent processes for all backflushes have been completed.

    End of the note.

Note Note

Note, that for technical reasons it is not possible to have different reporting point structure versions for one order. If, for example, you have created backflushes for an order and have then subsequently canceled them, and the master data assignments for the order have changed, it is possible that no further backflushes could be created for the order because the reporting point structure had been modified. If this occurs, you must either establish the original master data assignment for the order, or you must delete the order and create a new one, for which you can then create the backflushes.

End of the note.

  1. In the Quantities section of the screen enter the quantity you want to backflush.

    Note Note

    If you want to post a scrap quantity instead of a yield, switch to Scrap . When posting scrap, use the F4 help in the Reason field to select one of the scrap reasons you defined in Customizing.

    In the Dates section of the screen, enter the posting date and time zone as well as the execution start and end of the backflushed data and the forecast finish of all the data to be backflushed, so that the system can adjust the capacity requirements.

    Record the entry data, the batch number, if batches are used within the production, and any required text.

    End of the note.

  2. If the entries were incorrect and you want to start again, choose Delete entry .

  3. Save your entries.

    The system displays a success message.
