Executing a batch file in BODS script does not work

Hi all,

I read so many posts about this topic and yet can't find the solution to my problem:

I want to execute a batch job that opens an excel file. The Code I use is:

exec('Batch_jobs\\CS_TOOL_BATCH.bat','', 8);

However the job starts but never finishes and the batch job also does not run.

Would be really appreciated if someone could help me

Thanks

Chris
