Hi Experts,
Requirement is to issue error message if line item with duplicate combination of fields occur in shopping cart.
For example: Requisitioner adds a catalogue item to the shopping cart for a particular location, the system needs to check if that item is already present in that shopping cart for the same location. If this item is a duplicate in the shopping cart. system issues a error message.
The same item can appear in the shopping cart if is requested for different plant.
Only the combination of a item and its plant has to be unique in the shopping cart.
How to achieve this using internal table?
Thanks.
