No data getting extracted in the setup table for Purchasing extraction

Hi all,

We are trying to implement Purchasing Information, Purchasing Data Item Level (2LIS_02_ITM), Purchasing Data Header Level (2LIS_02_HDR), Purchasing Data Schedule Line (2LIS_02_SCL), we have activated the extract structure, filled the set-up table and tried to look into the setup table but it does not show any records (even RSA3 do not show), the job log shows everything fine, then we tried deleting the set up data and again filling the set up table, still the result is same, I searched in SDN and got to know that, it has something to do with R3 patch level, but we are having SAP_APPL 50. I am not sure why this is happening, does anyone has any solution for this.

regards,

partha
