WIP transfers in the Assembly Control (ASC) module
WIP transfers consist of generating the transfer order, executing the issue, and executing the receipt. How these processes are performed, depends on the question whether the assembly lines between which the WIP is transferred, belong to the same company or not.
Single company
In a single-company situation, when the assembly lines are in the same company, these processes can be done manually, semiautomatically, or automatically. This parameter is defined on the Assembly Line in the Assembly Lines (tiasl1530m000) session.
The following chart illustrates how the process occurs for each parameter setting. For example, if you select Manual, the transfer order is generated by the execution of the Generate WIP Transfer (Trigger process 1). At the same moment, the warehouse order is unblocked, making the transfer issue possible. The execution of the WIP issue and the WIP receipt must be performed manually when the trigger is set for Manual or for Semi Automatic.
Description: The concept of process triggering holds that an event at a certain line station is used as a trigger to fire the execution of a session. Following is the description of triggers as mentioned in the table below:
- Trigger process 1 = Generate WIP Transfer.
- Trigger process 2 = Execute WIP Issue.
- Trigger process 3 = Execute WIP Receipt.
| Parameter Setting | Manual | Semi Automatic | Automatic |
|---|---|---|---|
| Generate WIP Transfer | Executed by trigger proc. 1 | Executed by trigger proc. 1 | Executed by trigger proc. 1 |
| Unblock warehouse order issue | Executed at same moment of trigger proc. 1 | Executed by trigger proc. 2 | Executed by trigger proc. 2 |
| Execute WIP | Performed manually (WH) | Performed manually (WH) | Executed by Issue trigger proc. 2 |
| Execute WIP | Performed manually (WH) | Performed manually (WH) | Executed by Receipt trigger proc. 3 |
Multicompany
In a multicompany situation, when the WIP is transferred between different companies, the WIP transfer is handled by means of intercompany sales and purchase orders. These orders are handled by Warehousing, which uses the multicompany functionality of the Enterprise Modeling Management. The EMM module also includes procedures for intercompany invoicing, document printing, and so on. The generation of these orders is triggered by the Generate WIP Transfer (tiasc7200m000) session.
- A WIP transfer is always performed at the last line station of the current assembly line. You can generate the WIP transfer at an earlier station, but still the WIP transfer is actually performed at the last station. And only the Line Station Order (LSO) of the last line station registers the WIP transfer.
- In Assembly Control a WIP is always transferred between assembly lines and not between work centers. In this respect ASC differs from Job Shop Control, which can also transfer WIP between work centers.
- You can run the related sessions by means of the Process Trigger Definition (tiasl8100m000) session.
The following sessions are used for WIP transfers:
- Generate WIP Transfer (tiasc7200m000)
- Execute WIP Issue (tiasc7201m000)
- Execute WIP Receipt (tiasc7202m000)
- Line Station - Assembly Orders (tiasl6510m000)
- Assembly Lines (tiasl1530m000)
- Assembly Order - Line Station Orders (tiasc2510m000)
