What transaction is used to update price changes in the material master?

The transaction used to update price changes in the material master is associated with MR21. This specific transaction is designed for changing the price of materials in inventory, reflecting adjustments that may be necessary due to changes in market conditions, cost of production, or negotiations with suppliers. By using MR21, users can effectively manage the valuation of materials to ensure that the financial reporting and stock valuation reflect the most accurate and current pricing.

Other transactions such as MM01 and MM02 are primarily used for creating and changing material master records, respectively, but do not focus specifically on adjusting pricing. MM01 is for initiating new material data, while MM02 allows for the modification of existing material records, but those modifications can cover a broader range of data beyond just pricing. MR01, on the other hand, relates to the transfer of materials and does not serve the purpose of price updates directly. Therefore, MR21 stands out as the dedicated transaction for this specific task.
