what is demand source on item location

AI generated answer (using internal Slack threads):

In NetSuite, the demand source on an item location refers to the origin of the need for that particular item at a specific location. This could be due to sales orders, work orders, or transfer orders from that location. In a multi-location setup, you might have a centralized purchasing location and multiple demand locations. The demand planning or Material Requirements Planning (MRP) can be run based on the demand from all other locations. However, the Sales Order (SO) demands in the demand locations are typically used to generate planned Transfer Orders (TOs). These TOs are considered demands from the perspective of the centralized purchasing location and are used by that location for supply planning, such as Purchase Orders (POs). When it comes to updating the inventory location on a sales order line, you might encounter some challenges due to dependencies and backend processes. For instance, the inventory location field has a dependent field, inventory subsidiary, which is sourced upon selecting the inventory location. This can potentially create an infinite loop if not handled correctly. One way to avoid this is to ensure that the post-sourcing only triggers when the

is the specific field you need. As for viewing an item's location availability on the Sales Order, you can create a custom field that uses sourcing to get the available quantity. This can be achieved by creating a new decimal number transaction line field where the source list is set to item and the source from is set to available. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
