Purchasing or producing long lead-time components

Long lead-time components that must be ordered or produced at an early stage can be added to a production file for long lead-time components. To order long lead-time components and transfer the component from the provisional production file to the final production file, follow the steps below. Then read how you can use the 'Check for long lead-time components' option to avoid duplicate purchase requirements.

Producing long lead-time components

It is also possible to create a long lead-time file for production parts that must be produced a long time in advance.

The starting point is a sales order containing a sales line. The product included on this sales line is a product that your own company produces. Its calculation can have multiple levels: it may have semi-finished articles consisting of other semi-finished articles, etcetera. Long lead-time components required in this structure must often be ordered even before the production structure is known. In order to register these items, you could first create an additional sales line with a dummy part you have created specifically for purchasing long lead-time items. Set the origin of this line to 'Production'. A production file will automatically be created for the dummy part.

Then, on the Production calculation for parts form, create a line on which you enter the long lead-time item. You can add multiple lines in order to purchase all long lead-time items for a particular order at the same time. Once you have marked the file as a file for long lead-time items, all underlying part lines will also automatically be marked as such (Continued tab).

Once you have authorized the part line, you can purchase the part.

After some time, the long lead-time item will be received. Once it is known where the purchase item will ultimately be used, move the long lead-time item to the target production file in which the long lead-time item will be used.To do so, use the Change purchase line destination process. This process also allows you to create a new part calculation line in the target production file, move part of the purchase line to the new destination, and delete the original calculation line.

Check for long lead-time components

To prevent components from being ordered or produced again at the time the final product structure is built, you can configure Isah to check, for each part calculation line, whether the part is already present in a production file for long lead-time components:

• Select the Check for long lead-time components option to use this feature.
• On the Production calculation for parts form, open the Long lead-time component tab to see the alerts and the origins of the part calculation line.
• From the part calculation line, open the informational Alerts for long lead-time components form, to view the origins and destinations of the part calculation line, including the quantities assigned. From this form, you can start processes to transfer the long lead-time components to the final production file:
  • For long lead-time items: Change purchase line destination
  • For long lead-time production components: Change production file destination
