Aisle Row and Bins in warehouse

Amit, I did a brief video demo on this (for a total new comer to ERPNext, so you’re likely familiar with these concepts). Pawan’s approach is correct, I would recommend creating your whole tree in Excel and importing it that way. One of the challenges with the Aisle/ Bin approach is that you end up with duplicate names (if you have five aisles you have five bin #1). So you should build your naming schema in manually: “Aisle 1 Bin 1”.
