Can a macro corrupt? Exact same code works in other macro.

Try to change run flags. With flags 0 it does not wait for the window. Try 0x800. Also, use something more precise instead of "SAP". Maybe some window with "SAP" in title exists. For example, if macro name includes "SAP", then QM window title also includes "SAP" when the macro is opened.
