Thanks Jen. I know I need to enter value to MAX field before I can set the reorder point qty but the problem is the Max column is neither in the "Add/Edit multiple list entries" nor in the mapping of the advanced import with formatted excel. 

I wanted to use Excel import to map and update the MAX column for all the inventory items or at least to use the "Add/Edit multiple list entries".

It is too much job to open every individual inventory item to enter the MAX field for thousands of items. Please advise where can I find that "MAX" column in the mapping of the advanced import and in the Add/Edit multiple list entries

Thank you for your help
