Please inform if there is any limitation of file size which can be uploaded and transferred from Pega as attachment to Live Link using Connect CMIS method having End Point Server Type as SOAP. Pega Version used is V7.1.8
By default, file attachments are limited to 1GB in size. You can set a higher or lower limit through an entry in the prconfig.xml file or a Dynamic System Setting. I believe it would be applicable toConnect-CMIS also.
