A user surprisingly finds out the option ‘Windows Device’ is missing at the print screen list popup window for all transactions at one system but another not. I could ask Basis for help to get a quick answer like below by check SPAD setting: Spool: Deactivate Selection For access method ‘F’, you can use this option to always use the target device specified for the SAP output device and not display a field in the print dialog box for the user to select a device. For access method ‘M’, you can use this option to prevent the mail address of the creator of the output request being used or the display of a field in the Print dialog box. As Basis is not available at the moment and I have some time on Friday afternoon, so I decide to find out from technical. 1. Get screen field name and program name&screen number from Technical info button 2, Go to screen program LSPRIO04 and search field name ‘PRIPAR_EXT–OSPRINTER’, we can find when this field will be hidden. As IS_FRONTEND is always true while using SAP GUI, so focus on the field: no_directory_box. 3. keep searching ‘no_directory_box’ will find out it’s been set as True by FM:‘RSPO_FRONTEND_PRINTERS_FOR_DEV’ 4. Now just continue to check when no_choice has been updated as true inside the above FM. Here it’s, as TSP03-PAMETHOD is ‘F’ for tested output devices at two systems, so the TSP03-PASTATUS is the key. data: hex type x, res type x, C_RSPOPNOCHOICE TYPE X VALUE 128. "----For system which windows device not been hidden ---- "tsp03-pastatus = 32 hex = tsp03-pastatus. " hex = 20 now! C_RSPOPNOCHOICE = 80 res = hex bit-and C_RSPOPNOCHOICE. " res = 20 bit-and 128 = 00 "----For system which windows device been hidden ---- "tsp03-pastatus = 160 hex = tsp03-pastatus. " hex = A0 now! C_RSPOPNOCHOICE = 80 res = hex bit-and C_RSPOPNOCHOICE. " res = A0 bit-and 80 = 80 (little confused about bit-and operator but it doesn’t matter here as they’re different :D) RES is 80 which leads to no_choice = true, then leads to no_directory_box = true, then leads to ‘windows device’ been hidden at print screen list popup screen. TSP03 is a table of Spool: Printer declaration so can compare& find out the checkbox of ‘No device selection at front end’ by printer setting TCODE: SPAD.
