| # Backflushing Requirements Prerequisites To backflush assembly parts and hours, the following conditions must be met: The line station orders must be Completed. The current session is, therefore, usually run when an assembly order is reported complete at a line station, from the appropriate menu of the Line Station - Assembly Orders (tiasl6510m000) session. The assembly parts must be allocated. Materials that were not allocated, can not be backflushed. Refer to Build Assembly Part Allocation (tiasc7240m000) for more information about the allocation of materials. Functionality During backflushing, the following happens for each line station order that is processed: The costs of different cost components are converted to the effective cost component structure by assembly line and item, defined in the Cost Price Calculation (CPR) module. The number of assembly hours that must be backflushed is determined. The assembly hours are posted and backflushed in People automatically. The number of assembly parts that must be backflushed is determined. The inventory is adjusted for each assembly part in Warehouse Management. The planned stock transactions for each clustered line station order are reduced. The Line Station Order Status is set to Closed. Parameters The way backflushing is carried out, depends on the Transaction Processing parameter, which you define in the Assembly Control Parameters (tiasc0100m000) session. Order Based Requirements are backflushed for each individual assembly order. Line Station Based Requirements are backflushed for each line station, with requirements of all the line stations orders added together. LN determines to which clustered line station order and time bucket the materials belong. LN combines the backflushing of materials that belong to the same time bucket, for a certain line station.

Debit | production WIP
Credit | inventory
Transaction origin: ASC Production Financial int. transaction: operation costs
