In this educational example, you are provided with an MRP (Material Requirements Planning) schedule for Item J. The task is to fill out the table with correct net requirements, planned-order receipts, and planned-order releases to meet the gross requirements provided. The lead time is one week, and you should leave the cells blank when the value is zero.**Initial Information:**- Item J- On-hand inventory: 35- Lead time (LT): 1 week- Safety stock (SS): 0- Order quantity (Q): Lot-for-lot (L4L)**MRP Table Breakdown:**1. **Input Data (Top Table):** - **Gross Requirements:** - Week 2: 80 - Week 4: 45 - Week 5: 60 - **On-hand:** 352. **Output Data (Bottom Table):** - **Period Columns (1 to 5):** - **Gross Requirements:** Only periods where there are requirements are filled. - **Scheduled Receipts, Net Requirements, Planned Order Receipts, Planned Order Releases:** These fields need to be updated based on calculations.**Explanation for Calculation:**- Begin with on-hand inventory and calculate for each period.- Determine net requirements by considering the on-hand balance, scheduled receipts, and gross requirements.- The planned-order receipt is the amount needed to meet net requirements, considering the lead time.- Planned-order release is scheduled to ensure the receipt aligns with the lead time.**Note:** This example assumes a blank cell indicates a zero value in the context of MRP planning. Calculations should derive when to order and how much based on these stipulations, ensuring inventory levels meet production requirements without excess stock.

The planned order receipt for item A is 200 in week 5 and the lead time is 3 weeks. Which week should the planned order release be?
One unit of A is made of three units of B, one unit of C, and two units of D. B is composed of two units of E and one unit of D. C is made of one unit of B and two units of E. E is made of one unit of F. Items B, C, E, and F have one-week lead times; A and D have lead times of two weeks. Assume that lot-for-lot (L4L) lot sizing is used for Items A, B, and F; lots of size 50, 50, and 175 are used for Items C, D, and E, respectively.
