| 6. Management of materials Code (1) |
| |
| material basic information includes material code, item name, item type, item category, Inventory Unit, and virtual item mark. and material status. These are the most critical materials in material management. Users should be very careful, complete, and accurate when establishing these materials. The main characteristics of materials must be clearly stated in the material specification column. |

| 6. Material Code Management (2) |
| |
| basic materials of materials include: (1) ABC Classification
double-click the item code bar, detailed material code information is displayed. |
ABC Classification: this is a common method of inventory control. The importance of materials in stock is divided by the amount of money occupied, and different management measures are adopted respectively. Generally, Class A materials account for a large amount of inventory funds, accounting for about 80%, but the variety accounts for about 20%. Category B materials account for about 15% of inventory funds, and the variety accounts for about 30%. Category C Materials account for about 5% of inventory funds, but the variety accounts for about 50%. The company can formulate different cycle check cycles for each type of materials. The cycle check cycle of Class A materials is short, and the check is carried out strictly according to the check cycle. It also develops an irregular inspection system, closely monitor the use and storage of such materials, minimize the inventory of Class A materials, and adopt a reasonable Ordering Policy. The cycle of C-type materials can be appropriately extended. In the ERP system, the ABC Classification code can be automatically calculated and generated. Of course, you can also modify this code. |

| |
| basic materials of materials include: (2) cyclic check cycle, (3) virtual item mark |
(2) Cyclic inventory check cycle:
the interval at which the inventory item is checked. You can modify the cycle of each item. During inventory check management, the system automatically determines whether to perform inventory check based on the previous inventory check date. (3) virtual item mark:
to enable the BOM of a product to express the manufacturing or assembly layers in a hierarchical manner, this concept sets some temporary accessories in the manufacturing process as material code. To facilitate management, multiple materials are packaged to form a virtual item, which reduces the workload during BOM creation. The main difference between a virtual item material and a general item is that although there are obvious sections in the production or assembly phase, the virtual item material is usually not stored in the database, but directly sent to the next process, continue manufacturing. Therefore, theoretically, virtual item materials are not in stock. In the MRP plan, when virtual items are encountered, if the virtual items have inventory, the net demand deduction is still allowed, and then expand down, the virtual item itself does not produce demand. When purchasing and manufacturing orders, you cannot directly open bills for virtual items. When a virtual item is created in a manufacturing order, if the inventory of the virtual item is sufficient and the item is not occupied, the virtual item is not expanded. if the inventory of the virtual item is insufficient or the stock is occupied, the virtual item continues to expand. |

The basic materials also include: (4) material status, (5) Number of days in stock, (6) Batch number testing cycle, (7) customer supply marks, and (8) Mandatory suppliers. |
(4) material status: whether the material is available.
(5) number of effective days in Stock: materials requiring batch number control may have a limitation on validity, such as battery.
(6) Batch Number detection cycle: how long will the batch number be detected.
(7) customer supply MARK: whether the material is provided by the customer. If it is provided by the customer, the inventory is not included in the cost. Generally, incoming material inspection is not performed. Do not make accounts payable during delivery.
(8) Mandatory suppliers. If specified, this item can only be purchased from this supplier. If this parameter is not specified, the system automatically finds the most suitable supplier for MRP calculation and procurement order placement.

The basic materials of materials also include: (9) Purchase type, (10) planned procurement marks, and (11) planned cycle |
(9) system purchase types: M-manufacturing and B-procurement, which are automatically calculated by the system. When the BOM can be expanded, the system purchase type is M, if the BOM cannot be expanded, its purchase type is B. Purchase orders can only be generated when materials of the Type B are planned to be purchased by MRP. Only manufacturing orders can be generated when materials with M type are scheduled to be purchased by MRP.
(10) planning procurement MARK: whether planning procurement is required. The procurement orders can be issued manually for planned materials. The procurement orders for unplanned materials can only be generated by the MRP requirement.
(11) planned cycle: This is a strategy for combined production and procurement. It specifies the number of days required for the materials to be merged before the first day. For example, material a has five requirements:
| Demand date |
2002/11/18 |
2002/11/20 |
2002/11/21 |
2002/11/22 |
2002/11/23 |
| Demand |
500 |
300 |
150 |
1000 |
2000 |
If the planned cycle of material a is 3 days, 11/20 of the requirements are raised to 11/18 days, And 11/22 and 11/23 are raised to 11/21 days. That is to say, the 11/18-day demand is 3150, and the-day demand is. |

Basic materials also include: (12) lead time, (13) demand lead time, (14) Low-layer codes, and (15) standard cost data for this phase |
(12) Lead Time: Manufacturing Lead Time or preset lead time for procurement. The materials must be placed to the supplier a few days in advance or produced a few days in advance before delivery or completion on the required date.
(13) demand lead-up period: when the material lead-up period cannot meet the delivery period, this defines the demand lead-up period. The total lead time of materials = procurement or manufacturing + demand lead time. Generally, this value must be 0, unless otherwise required.
(14) Low-Layer Code: automatically maintained by the system. Detailed descriptions are provided in the product structure section.
(15) standard cost data at this stage: detailed descriptions of standard cost establishment are provided in the Cost Analysis Section. TIPS:
The following SQL statement can be used to find all repeated item numbers:
"Select itm_itmnbr, count (*) from itm_mstr group by itm_itmnbr
Having count (*)> 1" |
