WalMart 816 vs. 4030

[Linda Sislan]

Our company is going to start the testing for the 816 vs. 4030.  Has anyone done this yet?   How does the 816 interact with other documents?  Walmart refers to REQUEST CARDS for pulling data through EDI.  I am not sure what this means.   Can anyone help.   Linda Sislan 440-975-4300 x.142
