Validation Station Issue

Is Validation station is compulsory in document understanding.I have 10000 thousands pdf
and accuracy issue in every pdf because pdf is dynamic and unstructured.
Please give me the solution

Hi @Himanshu_Pratap_Rana,
according to this documentation Validation Station, validation station is part of the DU and can be only used in projects that have at least basic DU structure (please see the requirements for document validation part in the mentioned link).
Also, you can take a look here
However, it is not a must for validation station to be used. If you want, you may not include it in your process, but that might cause some problems, such as incorrect data. So, it is recommended to be used, as in this type of task it is better if you have a human involved to validate the results.

I am not satisfied with your answer.
