Inventory Analysis
In the ERP inventory management module, the general manufacturing plant, in the end of the month, or a certain time will have to do a plant inventory counts, inventory warehouse inventory carrying amount and the number of warehouses are the same; in theory, should be the number of warehouses and warehouses physical book the number of consistent, but because management is not strict (such as: physical already in storage, warehouse storage is not the book; kind have been issued, the warehouse is not a library book; theft, loss, etc.) because, under normal circumstances, the physical quantity and warehouse inventory the number of books, there will be differences, warehouse personnel must in a certain time, the right to do an inventory of physical inventory. The role of inventory there are three: 1. To determine the true amount of material inventory for the production of authentic material information; 2. To make an inventory difference analysis, to identify the loopholes in management and hold responsibility for related personnel mistakes, and to strengthen management; 3 . For the material differences in the amount of inventory, financial to do manufacturing costs or management fees to handle, as the end of the cost of production sharing. Therefore, a focus on inventory management is stock inventory operations, the company must attach great importance to them, because the cost of materials enterprises in the manufacturing sector account for a large proportion.
Inventory Invoicing Monthly Report
In the ERP inventory management module, at the end of the financial officers generally require warehouse staff to provide a monthly inventory report Invoicing, because for small and medium manufacturing industries in general, the general does not have have IE (Industrial Engineering) departments, so the standard working hours, the actual measurement of working hours are generally unable to do so, then for the cost accounting for manufacturing costs can not be accurately carried out, artificial wage share, costing only a simple accounting to the cost of materials only. Therefore, financial officers need to warehouse staff to provide a variety of materials, Invoicing monthly report, the average unit price of the material calculated to calculate the actual consumption of materials, then the material cost of the end of the calculation came out, together with manufacturing costs, labor wages, outsourcing processing charges, then the month's total production cost of basic computing out. So, for small and medium manufacturing industries, it is important to provide such a report to the Finance staff to provide cost-accounting purposes.
Calculation of MRP process
Program management module in the ERP, enterprise PMC sector-related planning staff will make relevant material requirements planning (MRP) and master production schedule (MPS), I will first describe the general process of MRP computing, ERP system, material requirements planning is through the BOM of low-level code started to operation, in operation prior to first understand the following terms MRP: low-level code, independent demand, the relevant requirements; the total demand (sales orders, sales forecasts), inventory, safety stocks, temporarily closed capacity, in-transit amount (planned in transit, purchasing in-transit, manufacturing, in-transit), the amount allocated was replaced volume, replacement rate, alternative priorities, plan inventory, the net demand for such basic concepts, its calculation formula:
Net demand = total demand - the amount of inventory safety stock quantity + - temporary income the amount - the amount of + has been assigned in-transit traffic - the amount being replaced
This is the ERP system, the calculation of material requirements planning process, if you want the results of computing an accurate, we must guarantee that the process of data accuracy, which is why many companies can not really run smoothly MRP calculated.
MPS operation process
In the ERP program modules, corporate PMC department will make the relevant Material Requirements Planning (MRP) And the master production schedule (MPS), The previous paragraph has been talked about material requirements planning (MRP), the MPS to describe the computing process, the basic use of the existing ERP are an infinite capacity scheduling method, through the lead time (procurement lead times, production lead time) + rest day operations involved in reversing MRP introduce a scheme to issue (production planning, procurement plans) the date, this is only a rough capacity requirements planning; But for enterprises, the production is basically fixed (equipment and personnel are fixed), we must also consider the capacity of our system, the plan can meet the schedule, so we have to identify each plant's total effective hours of work per day, each product in each process of the single-piece processing time, lead time, etc., the system calculate had arranged for the production of the work out of the master plan for a single consumption of man-hours, and the total effective hours of work per day compared to determine whether the ultra-short production consumption, ERP system, best to see what programs work to keep a single occupancy of these hours, only the case in order to work on the super-consumption for scheduling a single adjustment, so that our schedule is feasible, that is, small capacity planning.
