Purpose

If a model mix is assigned to the line balance and a complex product structure has been maintained for the model mix items, the calculation of the weighted mode duration may take a long time. The reason for this is the long evaluation of the object dependencies that cannot be avoided. For a complex product structure, the number of value assignments is multiplied by the possible combination of components and their characteristics.

As the online evaluation of the line balance in the Activities tab page may cause a runtime termination, this program, which can be run in the background, is available.

Using this report does not improve performance. The performance level is not changed as a result.

This report provides the same functions as available in the online evaluation in the iPPE Workbench. As well as the batch option, this report also provides an interface to the customer BAdI. You can use this BAdI to define that the result of the model mix explosion can be saved and the display structure of the line balance relationships with the weighted duration can be reused.

Integration

Prerequisites

You have defined a line balance with allocations between product and process structures. You have assigned a model mix to the line balance. This model mix contains the portions of every material variant and still determines the weighting of each valid activity in a certain material variant.

Features

Selection

The report has the following input parameters:

• One line balance to be exploded

• The key date for the explosion

Standard Variants

Output

The result is that the weighted factors of the mode are calculated and the weighted duration of the modes are displayed together with other information from all line balance relationships.

Activities

Using both input parameters, the system explodes the assigned model mix. That is, it explodes every individual model mix item with the relevant product and process structure. Using the explosion date, the system determines the valid components and using the component assignment and the structure of the activities in the process structure, the system determines the valid activities. To do so, the system reads the valid modes of the activities found.

After the explosion, the system determines the weighted factors of the modes. The factor is unique for a mode with a certain line balance.

The weighted duration is the duration of the mode, multiplied by this factor. Once this factor has been saved, the weighted duration can simply be recalculated. You only have to instruct the system to recalculate the explosion when the product structure and the structure of the activities are changed.
