+### Concept of Transfer Qty Bucket
+In the case of **Repack**, Quantity that comes in, isn't really incoming. It is just new stock repurposed from old stock, due to incoming-outgoing of the same warehouse.
+
+Here, stock is consumed from the FIFO Queue. It is then re-added back to the queue.
+While adding stock back to the queue we need to know how much to add.
+For this we need to keep track of how much was previously consumed.
+Hence we use **Transfer Qty Bucket**.
+
+While re-adding stock, we try to add buckets that were consumed earlier (date intact), to maintain correctness.
+
+#### Case 1: Same Item-Warehouse in Repack
+Eg:
+-------------------------------------------------------------------------------------
+Date | Qty   | Voucher |             FIFO Queue           	   | Transfer Qty Buckets
+-------------------------------------------------------------------------------------
+1st  | +500  |  PR     | [[500, 1-12-2021]]   				   |
+2nd  | -50   |  Repack | [[450, 1-12-2021]]   				   | [[50, 1-12-2021]]
+2nd  | +50   |  Repack | [[450, 1-12-2021], [50, 1-12-2021]]   | []
+
+- The balance at the end is restored back to 500
+- However, the initial 500 qty bucket is now split into 450 and 50, with the same date
+- The net effect is the same as that before the Repack
+
+#### Case 2: Same Item-Warehouse in Repack with Split Consumption rows
+Eg:
+-------------------------------------------------------------------------------------
+Date | Qty   | Voucher |             FIFO Queue           	   | Transfer Qty Buckets
+-------------------------------------------------------------------------------------
