Hi all,
We have a situation where MRP plans manufactured parent and component parts sequentially, while in reality production can start before the supplying shop order is fully completed.
Example:
- Part A is a manufactured component.
- Part B is a manufactured parent part that uses 1 piece of Part A.
- The routing for both Part A and Part B results in approximately 1 hour lead time per piece.
- For a shop order quantity of 40 pieces, the total lead time becomes approximately 1 week.
As a result, MRP plans:
- Shop Order for Part A from Monday to Friday.
- Shop Order for Part B starting the following Monday.
This means MRP assumes all 40 pieces of Part A must be completed before Part B can start.
In reality, once the first pieces of Part A are completed, production of Part B could already begin. Therefore, we would like MRP to generate requisitions and planned shop orders with some degree of overlap.
Additional information:
- The product structures and routings have been migrated from our previous ERP system and are already in use.
- We would prefer not to redesign the product structures or routings.
- All materials in the product structures are linked to specific operations because multiple work centers and operations are involved in the routings of both Part A and Part B.
Question:
Is there any standard IFS Cloud functionality, parameter, planning method, transfer batch concept, operation-material relationship setting that allows MRP to plan overlap between manufacturing shop order requisitions without modifying the existing product structures?
How do other companies handle situations where downstream production can start before the supplying shop order is fully completed?
