Hi Srideep,
please check the length and the type of Infoobjects first if they match with the source data. Also, please tick the box Lowercase letters. Last, when you do the PSA, you can fix the errors manually wherever is the wrong characters. It is normal that if you have errors from the PSA to DSO and then try to load from one DSO to the other DSO. You should first successfully load to the first DSO and then if everything is fine, you can load to the second DSO from the first DSO.
It throws the same error, because it uses the same data from the first PSA. When you copy from one DSO to the other DSO, you do only the transformation and DTP. The PSA comes from the one that fills the data in the first DSO.
Hope this helps.
Best,
Regys
