How to add a discount to a specific line item using Simphony Extensability

[SaberPOS]

Hey guys. Does anyone know how to add an item level discount using Simphony Extensibility Framework? I see the OpsContext.ProcessCommand(new OpsCommand(OpsCommandType.Discount) { Number = DisObjNum }); but I'm unsure as to how to apply this discount to a specific item. Is there some method I need to use to select the line item first and then apply the discount? I can't seem to find anything about this in the documentation. Is it possibly not supported?

Thanks

If anyone else runs into this you need to use OpsCommandType.DetailSelected command to first select the item and then you can run the discount command. Make sue the discount Id you use is actually setup as a line item discount. OpsContext.ProcessCommand(new OpsCommand(OpsCommandType.DetailSelected) { Number = 1 });
