I assume its PDF/A files. Are you running IPM on Linux OS. Looks like you have hit a bug - Bug 11684958 : PDF/A FILE WITH SCANNED IMAGE NOT DISPLAYING CONTENT. There is a patch fix for this - https://support.oracle.com/epmos/faces/ui/patch/PatchDetail.jspx?patchId=12810114
Presently we have been working for invoices processing from Webcenter Capture to IPM in windows only not in Linux
even it is showing error for all type files ( tif, jpg, xls, docx,pdf) not only PDF, when i tried to see the invoices in IPM Viewer tool.
showing the above mentioned error in IPM Viewer for all formats of invoice files when i process invoices from webcenter Captuture to IPM in Windows installed machine
anyone, kindly help me to resolve this issue.
