This is similar to stock trading warrants. When long and short positions move in the opposite direction of the market, risks arise. To manage these risks, it is necessary to distinguish between inventory linked to sales contracts and those not linked.<\/p>\n<p>To make this distinction, at the time of the purchase contract, that is, when issuing the P\/O, it is necessary to link it with the sales contract (S\/O number) and manage it in the inventory management system along with the receipt number.<\/p>\n<h2>Long and Short<\/h2>\n<p>Items for which sales contracts are not confirmed at the time of receipt are entered as long positions, and an S\/O number is assigned when the sales contract is confirmed.

For risk management, it is necessary to distinguish between inventory linked to sales contracts and those not linked. This reduces risks when the market moves in the opposite direction.<\/p>\n<h3>What is a long position?<\/h3>\n<p>A long position refers to items for which sales contracts are not confirmed at the time of receipt. These items are assigned an S\/O number when the sales contract is confirmed. Proper S\/O number assignment in the system is crucial for long position management.<\/p>\n<h3>How are S\/O numbers managed?<\/h3>\n<p>S\/O numbers are managed by linking them with sales contracts at the time of the purchase contract. By assigning different S\/O numbers at the time of receipt and when the sales contract is confirmed, they are efficiently managed in the inventory management system. This system is introduced in Japanese factories in Indonesia.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Managing long and short positions is vital for risk management in the inventory business.
