How to update new data to 2LIS_02_ITM

Hello dear all,

I have created a new PO in the ECC side, when I used RSA3 to check 2LIS_02_ITM datasource which is nothing in there. After then, I went to the LBWE to schedule control job immediately, i saw extractor queue transport to BW queue ( I used RSA7). But after then, I tried to use RSA3 to check this datasource again, it is same as before. So do some one kow how to pull data to 2LIS datasources in the ECC side?

Thanks,

Cherry
