Use

Production backflushes are always carried out at reporting points. There is no backflush without a reporting point. Therefore, at least one reporting point must be defined at the end of the line network.

You define the reporting points for a line segment in line design in Integrated Product and Process Engineering , and you assign them various reporting point types. If you work with shop-floor-oriented repetitive manufacturing with iPPE, you define the reporting point at the mode of the activity.

The reporting point determines, whether in a production backflush

the capacity is reduced,

the goods movements and activities are posted

the preceding reporting point is automatically backflushed.

In the case of line-based production, the goods reciept for an output node is always posted for the last reporting point on the line.

When you work with a backflush in shop-floor-oriented repetitive manufacturing, the system assumes that the indicators Reduce Capacity and Post Goods Movements and Activities have been set, even if you have not done this explicitly.

In shop-floor-oriented repetitive manufacturing, the goods receipt for an output node is always made at the reporting point that is assigned to the output node, as long as the Post Goods Movements and Activities indicator is set. If this indicator has not been set for the particular reporting point, the goods receipt is made for the next reporting point for which the indicator is set.

If a preceding reporting point has been backflushed automatically, it can then no longer be backflushed manually, and it will be backflushed automatically with every further backflush.

Reporting points RP1, RP2, and RP3 are assigned to a line in this sequence. Reporting point 3 is defined so that predecessor reporting points are backflushed automatically.

8 pieces have already been manually backflushed at RP1. 1 piece has already been backflushed at RP2. RP3 has not yet been backflushed.

A backflush at RP3 with a quantity of 5 pieces causes an automatic backflush at RP2 for 4 pieces. RP2 can then no longer be backflushed manually.

A new backflush at RP3 of 5 pieces creates a further backflush of 5 pieces at RP2, and of 2 pieces at RP1. From now on RP1 can also no longer be backflushed manually.

Note, that in both the line-based production as well as the shop-floor-oriented repetitive manufacturing with iPPE, the system cannot determine additional information (for example, the production supply area) for created components manually. That is, the goods movements for these components will contain errors. If you create components manually for an order, you must also adjust the corresponding goods movements manually. Goods movements for manually created components are always posted with the last reporting point. For further information, see Entering Variances .

Prerequisites

You have defined the reporting points according to the type of production either in the line design, or by using the mode for the activity. When working with repetitive manufacturing you can determine two reporting points for each line segment, one at the beginning and one at the end of the segment. See also Assigning Reporting Points .

In the line network case, it can be the case that two reporting points on different hierarchy levels are identical. If this occurs the backflush still functions correctly. However, only one of the reporting points is displayed and the backflush then takes place for this reporting point.

Procedure

In Customizing for APO, choose Cross-Application Components ® Integrated Product and Process Engineering (iPPE) → iPPE Line Structure Administration → Define Reporting Point Types

Enter the description of the reporting point type and select the indicator you want.

Save your entries.

For line-based Production the following applies: If you have set the Backflush components indicator for a reporting point, then not only are those components backflushed and the production activities posted that are assigned to this reporting point, but also the components and production activities of the preceding reporting points, as long as these do not have the same indicator and as long as they have components assigned to them. Subsequently all previous reporting points, except ones with the same indicator, are tested and these components that are assigned to reporting points are backflushed and the production activities are posted.

The same procedure is used for the reporting point type Reduce capacities .

If you have planned scrap for an activity on the line, note that you must ensure that the reporting point for the corresponding activity is defined in such way that the goods movements are also posted at the reporting point. If the reporting point does not have this attribute, this can result in the withdrawl quantity posted being too small.

For matrix orders, alongside the rules mentioned above, there is a special rule that the components of a line segment are backflushed at the first reporting point of the line segment, as long as the reporting point has the indicator Backflush components . This does not necessarily have to be at the end of the line segment.
