Kumar,
Your replies to my first question is correct.
As for my second question is.. my question is asking how to make the field Des Bin to allow changeable.
For example, my warehouse guy notice the actual bin should not be the storage bin proposed by the transfer order (i.e. transfer order which is printed out and not yet confirm) when he bring the stock to the actual bin location... see below how to make the field to be changeable in the RF screen?
thanks.
