Utilizing CA Detector for DB2 for z/OS option 1 - SSID current interval data. On the DETECTOR Planname Summary Display screen it appears that the Total/Avg field should allow entry. When moving to the field to set Total/Avg to A the field is protected.
This problem appears to be a QWS3270 emulator restriction when the Enable Entry Assist is flagged. Enable Entry Assist was checked within QWS3270 and the field Total/Avg is in column 80. The best course of action would be to disable or uncheck the Enable Entry Assist option within QWS3270 under Options / Session / Entry Assist.
