Fourthshift ERP System Study Notes (1)

The company plans to switch from fourthshift ERP to sap erp, which takes one year to switch. You need to continue using fourthshift ERP within one year. To sum up and learn how fourthshift ERP feels.

Fourthshift ERP system principle:

1. The clerk places the sales order Co (customer_order)

2. MRP (Material Requirement Planning material demand plan)

① Production requirements

② Procurement requirements

③ BOM (Bill of Material material list)

Bom comprehension:

Suppose we need to produce 10 orders and deliver the goods on 5.10 day. The pen production, pen cap, pen core, and pen cover are purchased from the supplier.

Formula: supply = demand + safety stock-Inventory

Glossary:

Safety Stock (SS) is also called safe storage capacity, also known as insurance stock, it refers to the estimated amount of insurance reserves (buffer stock) to prevent uncertain factors (such as a large number of unexpected orders, sudden delay of delivery, increase of temporary usage, and delayed delivery ). Safety Stock is used to meet the demand for advance. Under the given safety stock condition, the average stock can be described by half of the order quantity and the safety stock.

Safety stock can be set in advance, assuming that the current safety stock is always 2

According to the formula, the supply of PEN covers = demand 10 + Safety Stock 2-stock 4 = 8

Refill supply = demand 10 + Safety Stock 2-stock 20 =-8

Pen Cap supply = demand 10 + Safety Stock 2-stock 5 = 7

The result is negative, indicating that no purchase is required.

Calculated based on the MRP procurement requirements: 7 caps and 8 pen sets are required;

According to the MRP Production requirements, the pen cover must be delivered before the 10th day. The pen cover should be produced on the 10th day and completed on the 10th day;

Pen caps arrived before 5.8, and production started on 5.8, with 10 production completed on 5.10.

3. Orders are placed by various departments: CO, Mo manufacture_order, And po purchase order)

① Assembly Order (CO)-> 10-> corv Assembly warehouse receiving

② Production order (Mo)-> 10 pens-> morv production warehouse receiving

③ Purchase Order (PO)-> 7 GB pen caps, 8 pen covers-> warehouse receiving from porv

4 ship-> customer
