Hello

Thank for your reply.

However, doing an inventory adjustment by" import product" is not a good way.

It still takes a lot of time.  (I need to know current stock and calculate the final stock)

What I want is there is a way just only for importing the number I want to add or reduce. 

If we can have the simple way, it would be very efficently. 

For example

SKU   ajustQTY

ABC   -10

FED   +20

UYT    -5
