I got a error when I try to submit purchase invoice.
I found the solution, I have made those item as batch number, So If I insert batch number and submit will be OK.
The problem is the MSG.
It is pointing no where saying invalid naming series do not make any sense!!!
Possibly you changed the default naming_series spec so the key is now malformed? The problem and message is the parser now does not recognize it - search the forum for naming_series ideas here Packing slip naming series wont change from default - #2 by kennethsequeira
