Fernanda is right. These look like references to calling a program, subroutine or function in a computer program: "llamada a riesgos" = calling the Risks module, "llamada a la aplicación de la APP de Apertura de Cuentas" = the application call to the Open Account APP, "la llamada al masivo de tarjetas" = (something like) the call to the mass cards module (I don't kn ow what mass cards means). Fernanda should put in her translation ("call").
