Engineering BOM Management – Usage > Create and maintain Usage BOM
Discontinue a part
Sometimes a part is unavailable due to logistic issues or raw material shortages. In such cases, you can remove that part for a finite amount of time and reintroduce into the product later.Example Imagine that you have a released car GPS module which is effective from January 1, 2023 to December 31, 2024. Due to a semiconductor shortage, you want to discontinue the part for 6 months, starting June 1, 2023 until December 31, 2023. After December 31, 2023, you want to reintroduce the part into to the product. Procedure Create a change notice with a release effectivity range for the duration of the part discontinuation, and set it as an active change.
Open the engineering BOM and select the released part.
