| # Closing Assembly Lines Prerequisites You can only close assembly lines by means of this option, if the following conditions are met: You use Line Station Based transaction processing. The Transaction Processing parameter is set in the Assembly Control Parameters (tiasc0100m000) session. If you use Order Based transaction processing, you cannot use this session, because LN closes the line automatically when the assembly orders are closed, in the Close Assembly Orders (tiasc7210m000) session. All line station orders are Closed, which means that all line station orders for this day are backflushed. Functionality If you close an assembly line, the following actions are performed: The line surcharges are applied to the actual WIP. This happens before the production results are calculated. The results of the line are calculated and posted. The clustered line station orders (CLSOs) that are linked to the line stations receive the status Closed. In Line Station Based transaction processing, a CLSO is linked to a line station per day, and this CLSO holds all the parts requirements. Post-requirements After this session is run, you must delete unwanted data with the Purge State-dependent ASC Data (tiasl1200m000) and Purge State-independent ASC Data (tiasl1210m000) sessions. Financial Transactions The production result is calculated as follows:
    Production result = estimated WIP - actual WIP
The financial transactions that are posted, depend on the question whether the assembly line concerned is a main line or supplying line. If the assembly line is a supplying line, the following transactions are posted: Transaction origin: ASC production Financial int. transaction: Line surcharges
Debit | Production WIP
Credit | Surcharge coverage
Transaction origin: ASC production Financial int. transaction: Production result
Debit | Production WIP
Credit | Production result
If the assembly line is a main line, the WIP of every order is transferred to the calculation office of the order, which results in the posting of a WIP transfer issue and receipt. In addition to the postings provided in the previous paragraphs, the following transactions are also posted: Transaction origin: ASC production Financial int. transaction: WIP transfer issue
Debit | WIP in transit
Credit | Production WIP
Transaction origin: ASC production Financial int. transaction: WIP transfer receipt
Debit | Production WIP
Credit | WIP in transit
Note If you use Line Station Based transaction processing, you can only have results per assembly line per day. If you run this session for a range of days, that is, for every day that the line surcharges are applied to the actual WIP of that day, the production results are calculated and posted for each day. The final outcome is a result that is calculated per assembly line per day, and is logged to the last line station of the assembly line. Line surcharges are applied to the actual WIP before the production results are calculated. The WIP figures apply to all the line stations of all the orders on the day concerned. You can reopen an assembly line by booking extra hours in People. You must then close the assembly line again, with the current session.
