Dear SAP Experts,
I create a parameter ID ZKONTO and want to assign it for data element KONTO. I use the access key (provided by Basis Team) to modify object KONTO. However, it seems the field Parameter ID is disabled in Further Characteristics tab.
You can see that I am in Change mode 
. I would be grateful if you can suggest the solution.
According to this link https://help.sap.com/saphelp_nw73ehp1/helpdata/en/90/8d7307b1af11d194f600a0c929b3c3/content.htm, it says that "A field can be filled with default values from SAP memory using a parameter ID. A screen field is filled automatically with the value stored under the parameter ID of the data element only if this was explicitly permitted in the Screen Painter. To specify the parameter ID, go to the Further Characteristics tab page and make the entry in field Parameter ID."
So I assign and enable GET parameter ID in Screen Painter but it is still no hope .
Best regards,
Danny
