Building Lead Times - Manufactured Products Feeding Other Manufactured Products

Categorized as:

I am trying to build out lead times that build full lead time in the material plan on manufactured products that feed into other manufactured products. I am not sure if I am just missing the simple setting/solution. I only see the impact of the final products lead time impacting available to promise if it is not in stock or needing to replenish safety stock. Currently we could have 2-3 levels of products that could feed into the final product. Simplified example Final (2-day), contains Items  Read more...A (1-day) and B (2-day). I would be expecting/hoping to see a 4-day lead time, but only see 2-day lead time from the final product.

Currently, the best solution I have is to either add administrative time or manually build lead time offset on the final product. Second option turning off dynamic lead time. Show less...

Hi Donald,
ATP checks on manufactured items don't naturally factor in material availability. There is some configurations you can play around with to turn it on, it's the same basic process as checking for production capacity before calculating lead time. But MTP and CTP calculations configurations get quite complicated and can be cumbersome to implement. A simpler solution is to include the "buffer" time in the planning time fence and then let the production planners/  Read more...schedulers move the order in according to material availability. So lead time = 2 days, PTF = 5 days, MOP proposal created at 5 days out, MO rescheduled when it's released in PMS170. Works best if you don't need to provide instant ATP/ order confirmation to the customer. Show less...

Hello William,
Thank you for this detail. In our situation, we are trying to build that "instant" confirmation for the customer order. Currently we do use a 5-day PTF. There is definitely some cleanup we need to do with our capacity planning that is impacting our plan.

Appreciate the feedback!
