Use
This processing step involves the exploding of material BOMs after you have selected the materials to be costed.
If you select all materials in all plants, you can skip the step Explode BOM. This step is only necessary if not all materials are selected, such as finished products only. If you have selected all the relevant materials, this step is not applicable.
How you explode BOMs depends on whether you work with variant BOMs (which cannot be configured) or configurable BOMs.
If you are working with variant BOMs, you only have to carry out the step Explode BOM if you selected specific materials for costing.
If you are costing all materials in a plant, you can skip the step Explode BOM.
If you are working with configured materials, you must explode the BOMs to determine a quantity structure for the cost estimate. The quantity structure of the configured material is created using the material components and operations that you select in configuration.
Procedure
The screen Costing Run: BOM Explosion - Change Parameters appears.
If you want to explode the BOM online, turn off the Background processing indicator. For more information, see
Background Processing.For more information, see
Logs in Material Costing.You return to the Edit Costing Run screen.
After the BOM explosion, you can display the section Costing results and display a list of the materials and their data (such as the plant and costing lot size) through the
costing level overview or material overview.If you have set the Background processing indicator, the materials are not exploded; instead, the system displays the Background Processing: Job Parameters dialog box. Enter the start date and other start criteria for the background job.
Choose Copy to schedule or start the job. Choose Goto ® Job Overview to branch to an overview of all background jobs.
Choose Goto ® Schedule Manager to access the
Schedule Manager.Result
After exploding the BOM, the system displays the status, number of materials exploded, number of materials processed with errors, and the number of materials that have yet to be processed.
To check all the messages that occurred during the BOM explosion, choose (Display Log). The
log provides an overview of the results of the BOM explosion and the option to prevent potential errors before carrying out further steps.Note that a BOM can include materials which
Multiple BOMs comprise several alternative BOMs for different lot size ranges or production alternatives, for example. You specify which procedure the system uses to look for the alternative BOM in Customizing for Product Cost Planning. (
You can display information on the selected alternative BOM by choosing Settings
® Field selection. If the BOM data indicator is set, the system lists the BOM number, the alternative BOM and the BOM usage for each material.The special procurement type specifies the plant in which the system searches for costing data. You control how the system looks for costing data by defining a transfer control ID in Customizing for Product Cost Planning.
BOM explosion is not required if other plants subject to special procurement have already been costed. If you have stock transfers between plants that have not yet been costed, you can dispense with the BOM explosion, provided you select all the relevant plants. Therefore, you do not necessarily have to explode the BOM in cross-company costing. It is only a requirement when the above conditions do not apply.
