Okay... So just to be sure I understand...
For stock that is sold but also issued for promotional sales work...
Change"Issues GL" value from 5700 to 6150 for "FIN" Stock Category.
Or... Alternatively... Create an entirely new Stock Category...
Copy FIN Stock Category to new Stock Category called" PRO"
Change the "Issues GL" value from 5700 to 6150
Set the Category for those items to "PRO"
Issue using Internal Stock Request
The manual does not mention "Issues GL" in the table so I just want to be sure.
From a reporting aspect it would seem there may be advantages to the second option.
