Hi

I am trying to navigate to the Purchase Requisition Lines screen in my bar chart lobby. I have the x-axis set as the Demand Code: 

And I would like to click on each bar individually and navigate to the purchase req lines page, and have the demand code filtering already applied. I have tried to include this filtering in the navigation section: 

However I am getting a type conversion error when I try to test the lobby navigation: “:{"code":"TYPES_NOT_COMPATIBLE","message":"The types 'IfsApp.PurchaseRequisitionLinesHandling.OrderSupplyType' and 'Edm.String' are not compatible."}]”

which makes me think that ‘DemandCode’ is an enumerated type OrderSupplyType, and $TDEMAND_CODE] is just a string. Is there a way I can cast the value of ‘DemandCode’ to be a string, inside my navigation? This way, i can filter the navigation properly upon the demand code.

Thanks,

mark
