| # WIP estimates assembly orders This topic provides you an overview of WIP estimate calculation process. When the assembly orders are frozen, their order content is frozen. When the assembly orders are frozen, the WIP estimates are frozen. A WIP estimates are the estimated costs per assembly order, per assembly line, and are based on the order content at the moment the assembly orders are frozen. A WIP estimate contains the costs of the assembly parts and operations of the main lines and supplying lines. A WIP estimate contains the total costs for the assembly order/product variant. A WIP estimate is frozen when you freeze the last line station order on the roll-off line. The cost price per assembly part is retrieved from the CPR module. The man and machine costs are calculated based on the operation rates retrieved from the CPR module. Additional assembly line surcharges are retrieved from the CPR module and are defined when: Transaction processing is Order Based: Defined for combination Assembly Line/Item. Transaction processing is Line Station Based: Defined by Assembly Line. Calculation of man/machine hours If the transaction processing parameter is Order Based, man and machine hours are calculated based on the operations which are linked to the line station variants (which are linked to the line station orders). Machine hours = Cycle Time (LSV Operation) * machine occupation (LSV Operation) Man hours = Cycle Time (LSV Operation) * man occupation (LSV Operation) If the transaction processing parameter is Line Station Based, man and machine hours are calculated based on cycle time and man/machine occupation as defined in the line station assignments Machine hours = Cycle Time (Assignment)* machine occupation by LINE STATION (Line Station Assignment) Man hours = Cycle Time (Assignment) * man occupation by LINE STATION (Line Station Assignment) |
