MACRO error when target position is equal to current position

I have a simple program P with a single line 1:J PR[8] R[20:ARIS_SPEED]% FINE ;. When the target position is the same as the current position, meaning the robot doesn't move when program P stars, I get "MACR-013 MACRO execution failed" "PROG-006 Line is not found". But, when the target position is different from current position I don't get those errors. These errors I see in Alarm history. What should I look for? What can be the problem?
