Background Printing of Costing Reports 
Use
You use this function if you want to print costing reports for many materials simultaneously and the lists are very long. You can print all costing reports in the background, such as cost component reports or itemizations.
Procedure

Through the BOM explosion indicator, you specify how the system selects the cost estimates for background printing (BOM explosion or Select cost estimates).
Only these cost estimates are selected and printed. The material BOMs are not exploded. That is, the cost estimates for the components in the relevant BOMs are not selected if they were not specifically entered as a material selection.
cost component view should be used, for example cost of goods manufactured or cost of goods sold
.
.The job will be started at the time specified. If you selected Immediate start, the job is started directly.
