Work with bin location in simple way

Hi Expert,

I have situation. we have 30 trucks that load our product, we do inventory transfer to truck (truck as bin location). every truck go around city to sell our product.

in the end the day, trucks back to office. then we create AR Invoice for every customer. It is not easy to input AR Invoice using warehouse with bin location, because bin location is in other window.

do you have any solution to make this simple ?

we use version: 9.1

Thank you,

Triadi
