It will take 100 to 1000s of documents to actually train Decipher to read documents. If you have six of them, then just keep resubmitting them to allow Decipher to get trained.&nbsp;<BR /><BR /><BR /> <DIV style="position: absolute; display: none; z-index: 16777271;"></DIV><BR /><BR />------------------------------<BR />Gabe Marquez<BR />Sr. Technical Consultant, Professional Services<BR />Blue Prism<BR />------------------------------<BR /> Thu, 15 Jul 2021 20:07:00 GMT gmarquez 2021-07-15T20:07:00Z https://community.blueprism.com/t5/University-Forum/Server-returned-error-code-151-Invalid-Batch-State/m-p/91262#M2503 Hi Experts,<BR /><BR />I am new to decipher.<BR />And i have been provided 6 set of PDFs to extract data from them and all are the structured one.<BR />I have added one file to Batch and them Data verify it and when i am adding more files to the same Batch it shows error : Server returned error code -151 Invalid Batch State.<BR /><BR />Do i need to add all files in One go?<BR />Or i can't train decipher on one file and extract data from other PDF based on that one trained PDF?<BR /><BR />Thanks<BR />Neeraj<BR /><BR />------------------------------<BR />Neeraj Shekhar<BR />------------------------------<BR /> Thu, 03 Jun 2021 09:35:00 GMT https://community.blueprism.com/t5/University-Forum/Server-returned-error-code-151-Invalid-Batch-State/m-p/91262#M2503 NeerajShekhar 2021-06-03T09:35:00Z https://community.blueprism.com/t5/University-Forum/Server-returned-error-code-151-Invalid-Batch-State/m-p/91263#M2504 Hi Neeraj,<BR /><BR />I haven't seen that error but, yes, you will have to submit all the documents at once.
