Hello I have a question about BI and I would appreciate your help. I have a table with 5 columns in order to calculate inventory per day. I can transfer the number from Final Inventory (Inventory - Used + Arrived ) to the next raw in Inventory using INDEX; however, I dont know how to insert the initial inventory number .in the inventory column. In excel this is pretty easy; the initial inventory goes in the first cell in the inventory column and the formula starts in the second row. I would appreciate the help to do this on Power BI using Power Query / DAX or M... Date // Inventory // Product Qty used // Product arrived // Final Inventory
As always, you are the best one
