InvalidCharacterError: Failed to execute 'atob' on 'Window': The string to be decoded is not correctly encoded

Hi,

I am trying to display an SAP standard report as aPDF document using PDF viewer in Neptune. I have converted the report output to spool and then to PDF Format and finally to XSTRING and used the FM 'SCMS_BASE64_ENCODE_STR' to encode it to base 64. However, after executing the PDFView.Show() method I am gettting an error message saying InvalidCharacterError: Failed to execute 'atob' on 'Window': The string to be decoded is not correctly encoded. How to resolve this?


I am attaching the PDF file that i am trying to display in the PDF view.

Hi Rahul


The file attached  is not Base64 encoded data. Can you please check it and try again with Base64 encoded PDF data ?

Hi Ole,


I had actually tried before by encoding the PDF data to BASE64 but it didn't work and I got the above error message in Chrome debugger. Please find attached the files 1. The PDF data in XSTRING format and 2. The XSTRING data converted to BASE64 format which resulted in the above mentioned error.


Appreciate your help.


Regards,

Rahul.

Hi Rahul


When I test your data from the txtafternew.txt, this is base64 encoded data and it works like a charm:



How is your code to show the PDF data ?

Hi Ole Andre,


It doesn't work for me. I guess I am doing something wrong but unable to idetntify what.. Please see the below code to show the PDF data :


var data = modeloPage.getData();


timeApp.to("oPage");

PDFView.Show(data.PDF_DATA);


and my oPage is bound to a structure(gs_pdf) with the following type 

types:
BEGIN OF ty_pdf .
TYPES: pdf_data TYPE string .
TYPES: END OF ty_pdf .


GS_PDF TYPE ty_pdf.


Do you see something that might be the problem?


Regards,

Rahul.



Hi,


Sorry but I have now identified the issue due to which the PDF was not getting displayed, I had forgot to check the Receive button in the binding of the button.

The issue is now resolved and the PDF is getting displayed.

Thanks for your help.


Regards,

Rahul.
