Part Replacement

You might need to replace one part with another in the bill of material. You can either scrap the old part or deplete the inventory.

Use these guidelines to specify a replacement part:

  • Leadtime must be set to 0 (zero).

  • Order policy code in the branch/plant record must be set to lot-for-lot.

  • Bill of material must be entered so that the new part is a component of the old part.

  • Stocking type must be set appropriately.

As MRP uses up the quantity of the old part, the quantity reaches zero. Since requirements still exist, the system generates a planned order release. This planned order becomes the requirement for the new item in the same period (because the leadtime of the old part is zero). MRP then plans the new part, which alerts the material planner to change the bill of material by removing the old part.
