For every document type or status field which we can see on front end, there is code which is finally stored in table.
e:g: Go to transaction /nme53n
Select any purchase req.
Select status tab from item.
See processing status field.
These processing status saves as N,B, etc in table.
I know there is way to see these codes followed by full description on front end screen itself. I think using personal settings, but dont know how to set this. Please let me know how to see status codes + description on front end.
