You can allocate overheads using percentage-based or quantity-based overhead rates for plan or actual data; alternatively you can use commitments data.

You can calculate overhead for single or multiple objects. Collective processing is based on selection variants that are individually definable.

You can start overhead costing for test and forecast purposes without updating the overhead calculation. The system then calculates the overhead, without you having to update the object (such as, internal order, cost center, business process). This enables you to identify and correct any errors before the actual calculation (such as, an invalid overhead costing sheet in the master data, or missing percentage rates).

You can run overhead costing online or in the background without a display.

The following reports are also available for overhead calculation:

• RKAZCO43: Overhead: Manufacturing orders and Product cost collectors
• RKAZKKPJ: Cost object hierarchy, general cost objects
• RKAZVA44: Actual overhead: Sales orders
• RKAZKSI4: Actual overhead: Cost Centers Including Activity types
• RKAZCPZI: Actual overhead: Business processes
• RKAZKGI4: Actual overhead: Internal and maintenance orders
• RKAZCJ45: Actual overhead: Projects/WBS elements/Networks
• RKAZKSP4: Planned overhead: Cost centers including activity types
• RKAZCPZP: Planned overhead: Business processes
• RKAZKGP4: Planned overhead: Internal and maintenance orders
• RKAZCJ47: Planned overhead: Projects/WBS elements/Networks
• RKAZKSO9: Commitment overhead: Cost centers including activity types

• RKAZKGO4: Commitment overhead: Internal and maintenance orders

• RKAZCJO9: Commitment overhead: Projects/WBS elements/Networks

You can use the dialog display to check the overheads that the system calculates based on the costing sheet.

You can create an overhead costing as often as required for each period. If any of the object values (for example, internal order, cost center, business process), or overhead costing values change themselves, the system updates the difference (can be a positive or a negative value).

The system determines the date during overhead costing as follows:

• Posting date:

• Plan processing of line items: First day of the period

• Actual processing: Last day of the period
  You can enter a posting date for overhead calculation. However, the posting date must be within the period for which you are calculating the overhead.
  To enter the posting date, choose Accounting ® Controlling ® Internal orders ® Period-End Closing ® Single functions ® Overhead rates ® Actuals - individual processing ® Extras ® Posting date.
• Commitments: The system does not write any line items

• Document date:

• Overhead calculation:

• Currency translation:

The system displays the results of the overhead calculation in a list for all objects, for which it has determined values. This list contains the following information:

• Basic list with information on current processing and number of objects processed.

• Detailed list with the amounts for each sender and receiver when you enter the credit cost element. If you already performed the overhead costing for the given period, the system only displays variances from the overhead already costed.

• Period drilldown in the planning data, should the overhead costing or simulation occur over several periods.

If errors occur during processing, the system refers you to an error log that contains an error listing.

You can print both the results list and the error log.

Enter the costing sheet required for overhead costing in your object (such as a cost center, business process, internal order, project or costing reference object).

• To run the overhead calculation in the background without a display, select Background processing.
• To simulate the overhead calculation, choose Test run.
• To check overhead calculations using the costing sheet, select Dialog display.

• To create a worklist for objects that do not have overhead applied to them, select Worklist (in Collective processing).
