The electron-impact collision strength calculations using different R-matrix code versions are performed for the 1s22s22p63s23p63d104l (l = 0, 1, 2, 3) configuration levels of the W45+ ion. The influence of relativistic effects on the bound-bound, bound-continuum, and continuum-continuum integrals of the collision strength is studied in quasirelativistic and relativistic approximations. A suitability of our introduced relativistic integrals method for highly charged ions is cross-checked by comparing results of different relativistic calculation methods.
