Issued w/ WEMNG after enhanced to 2LIS_02_SCL

I am currently have an issue with Received Qty of DataSource 2LIS_02_SCL. I enhanced scheduled qty (MCEKET-MENGE) and Received Qty (MCEKET-WEMNG) to 2lis_02_scl. I used rsa3 to validate these 2 fields against EKET table, the Received Qty is not correct. I am unable to figure out why this fields is not populated correctly. Would you please help. Thank you. Jennifer.
