Retrieving data from one store to Another
I have one question regarding a dev I am currently working on.
Here is the question :
I have a line item that retrieves quantity from a file :
Those quantities are splitted through different stores :
Now, the need is to merge the quantities of B01EUR and B03USD so that it becomes the quantities of B05USD. Basically, it should be :
if Store = B05USD then quantities of (B01EUR + B03USD).
But somehow i can't work around on how to do it
Thank you very much for your help
