sap系统，lr输出文件到本地磁盘

先定义要输出的数据所在的文件名称和目录

char *  filename =   "D://log/so4.txt";
long file;
char * SO_Number;

。。。。。

 sapgui_status_bar_get_text("paramStatusBarText",
  BEGIN_OPTIONAL,
   "Recorded status bar text: EM-Std Sales Order 4318006643 has been saved",
   "AdditionalInfo=sapgui1046",
  END_OPTIONAL);
 sapgui_status_bar_get_param("2", "SO", LAST);   //获得4318006643

 //lr_think_time(4);

 sapgui_press_button("Back   (F3)",
  btn3,
  BEGIN_OPTIONAL,
   "AdditionalInfo=sapgui1047",
  END_OPTIONAL);
 
 strcpy(SO_Number, lr_eval_string("{SO}")); //将获取的so号码 赋值给SO_Number

 fopen(filename,"r");
 fwrite(filename,"w+");

  file = fopen(filename, "a+" );
   fprintf(file,"%s\n ",SO_Number);
   fclose(file);
