For filling this table, we have to use the given data.

The gross requirement is calculated as the total requirement. By taking into consideration the number of units required.

On-hand inventory is the stock that we already have. This is given in a table.

Net requirements are calculated by deducting on-hand inventory from gross requirements.

The order receipt is how much we will recieve. that is same as Net requirements

The order release refers to when to place the order for it getting delivered according to our requirement. We use lead time here.
