Hello Gurus,

We have a  below requirement:

1. When  a user select " APO Product" in Show, in Shuffler,  then it shows a filed called Country in Drop Down. This filed is available in Properties tab of Product Master ( Global Data)

2. Requirement is to have same filed ( Country) available, when user select "Location Product" in Shuffler.

Any  help on this highly appreiciable.
