You need to hold the date against something- i.e. batch number.
That can be a batch for each receipt, or each packet or each shirt.
However you might just need one for each month or each season
You can then look at FEFO picking and sellable days.
The challenge is the add the batch to each batch of inventory otherwise how can you tell which is which? You also have to consider physical picking i.e do you take the nearest and tell the system which you took, or do you need to take the one the system advises which is on the top shelf at the back.
Be aware that without customisation AX POS does not take any notice of a batch number the system will just assume which one you sold- a good reason to have the same batch number for a period/several deliveries if that will work for you.
Consider whether your cycle counts will capture batch numbers of items at store.
