NativeProcess and cmd loop

Question

Hello,
cmd loop doesn't work correctly
file = file.resolvePath("C:\\Windows\\System32\\cmd.exe");
nativeProcessStartupInfo.executable = file;
process.addEventListener(ProgressEvent.STANDARD_OUTPUT_DATA, onOutputData);
process.addEventListener(ProgressEvent.STANDARD_ERROR_DATA, onError);
process.addEventListener(NativeProcessExitEvent.EXIT, exitHandler);
process.start(nativeProcessStartupInfo);
process.standardInput.writeUTFBytes('for /f "TOKENS=1" %%i in (\'"wmic Process where (Name="cmd.exe") GET processid | findstr [0-9]"\') do call :concat %%i' + "\n");
process.standardInput.writeUTFBytes('goto :fin' + "\n");
process.standardInput.writeUTFBytes(':concat' + "\n");
process.standardInput.writeUTFBytes('set str=%str%,%1' + "\n");
process.standardInput.writeUTFBytes('goto :eof' + "\n");
process.standardInput.writeUTFBytes(':fin' + "\n");
process.standardInput.writeUTFBytes('@echo pid%str%' + "\n");
public function onOutputData(event:ProgressEvent):void
var stdOut:IDataInput = process.standardOutput;
var data:String = stdOut.readUTFBytes(process.standardOutput.bytesAvailable);
are.appendText(data+"\n");
the cmd echo returns "pid%str%,%1"
Thanks

HI,
if your to internal table satisfy the bellow requirements
To use this following should be true
1)      Both tables should be sorted with the same key ( in the above case field1 and field2 )
2)      The mapping between primary to secondary tables should be
a.       one to many ( for one record in primary there are multiple records in secondary )
b.      one to one (for one record in primary there is only one in secondary )
Please note that other than the above 2 other 2 scenarios (many to many & many to one) will not work with the above logic and make sure you donu2019t use in such case.
3)      The secondary table should not contain a record which does not map to the primary table ( this will not happen if the secondary is fetched using for all entries from primary )
4)      Please make sure you do not delete any record from primary before using the logic which will make the point 3 false 
5)      If you were to use a 'AND' in where statement of the inner loop you should use or in the inner loop if condition in the above logic. 
then you can use the
Loop AT i_primary into wa_primary.
Loop AT i_secondary into wa_secondary from lv_index.
If ( wa_primary-field1 NE wa_secondary-field1 ) or
( wa_primary-field2 NE wa_secondary-field2 ).
Lv_index = sy-tabix.
Endif.
u201C your code comes here u201C
Endloop.
Endloop.
which is very fast i have check it in most of the reports gave performance issues
you can check the link for detail
