readfile

Options

The readfile command does not take any options.

Example

To demonstrate the readfile command, please do the following:

1. Open the script file for the IW21 transaction and enter the following code:

   					function isBlank(jvar){
      return(jvar == null || jvar == "" || jvar == void(0));
   }
   
   for(a=firstChild; a!=null; a=a.nextSibling){
      a.del();
   }
   
   pidx = 0;
   idx=0;
   
   text([0,0],  "Material" , {"size":20});
   text([0,22],  "Item" , {"size":20});
   text([0,44],  "Description" , {"size":20});
   
   create:{      
            inputfield([pidx + 1,0], {"size":20, "readonly":true, "name":"z_first_&V[pidx]" ,"nolabel":true});
            inputfield([pidx + 1,22], {"size":20, "readonly":true, "name":"z_second_&V[pidx]" ,"nolabel":true});
            inputfield([pidx + 1,44], {"size":20, "readonly":true, "name":"z_third_&V[pidx]" ,"nolabel":true});
   }
   
   set("V[z_checkfld]", "&V[z_first_&V[pidx]]");
   
   if(isBlank(z_checkfld)) {
     println("<<<<<<<<<CHECK FIELD>>>>>>>>>>" + z_checkfld);
     goto end_create;
   }
   
   pidx = pidx + 1;
   goto create;
   
   end_create:
   
   onUIEvents['Enter'] = {"process":iw21_readfile, "fcode":"/niw21"};
   
   function iw21_readfile(){
   
   println("<<<<<<<<<<<<INITIAL VALUE>>>>>>>> :" + idx);  
   openfile('file2.csv', {"delimiter":","});
   
   read:{
   println("<<<<<<<<<<<<READING VALUES>>>>>>>> :" );  
   readfile('file2.csv', {"z_first_&V[idx]":true, "z_second_&V[idx]":true, "z_third_&V[idx]":true});
   }
   
   set("V[z_currField]" , "&V[z_first_&V[idx]]");
   println("<<<<<<<<<<<<<<<<<Current Field>>>>>>>>>>>>>>" + z_currField);
   
   if(isBlank(z_currField)) {
     println("<<<<<<<<<<<<<<GOING END>>>>>>>>>>>>>>");
     goto end;
   }
   
   idx++;
   println("<<<<<<<<<<<<THE IDX VALUE>>>>>>>> :" + idx);
   goto read;
   
   end:
      closefile('file2.csv');
   }
   					

2. Create a file named 'file2.csv'. This file will contain the following data:

   					1030,10,valve 1
   1030,20,15 inch TV
   1030,30,monitor
   2120,10,door handle
   2120,20,paper clips
   2120,30,mouse
   3650,10,TV set
   3650,20,remote control
   4400,10,round cable
   4400,20,starter
   5003,10,test
   5003,20,test
   					

3. Save the changes and refresh the SAP screen. The IW21 screen will now appear as follows:
