Error:Loading Data from PSA to the target data

Hi All,

While Loading Data from PSA to the target data, I got error as attached.

Can some one please help me :

1. Just need to know how to know whether all records have been denied to entered or few as per error(attached)

2. how to check the which data gave error.

3. do I need to schedule data from data source to PSA or else I need to again Run the same DTP to load data from PSA to target data.

4. Is there any query to check the data which In entered.(like we have in SQL)

Thanks,
