MRP/DRP seems to ignore the lead time for kits with dependent demand. The promise date for a subassembly used in kit should be the action date of the parent item. In my example, the AMSUBKIT promise date should be the Action Date of AMKIT1
Question
Lead time for Kits
Hi Dennis. Kits do not have a unique lead time available. Kits re-used a lot of stock information from manufacturing sourced items as a starting point and may have used the manufacturing lead time as a quasi lead time for kits inadvertently. Notice that users with DRP but not MRP have this field available.
If you have MFG and are having multi-level kits, what would be the benefit of using a Kit vs a production order at that point?

The benefit is to avoid the cost of the manufacturing edition, Also, a client is a distributor and does not desire the complexity and multiple steps required for production orders. Not using the lead time violates the core concept of MRP./DRP,
For example, the distributor personalize items like name tags, in a an operation and needs to know when to replenish the supply of blank name tags. Other examples would be light assembly of inserting a purchased component into a purchased housing, or flashing software into a PC, tablet, or phone to personalize the unit for the customer.
The ISV solutions for light manufacturing claim to do “MRP” but as you well know, MRP/DRP has many complexities that these ISV packages avoid.
