The following article describes comparing Word documents.


Basic information

Webcon BPS Word Add-In allows to follow the history of changes in the documents placed in BPS repository (attachment list on SharePoint), compare documents which are in the repository, browse form field list and create templates for “Generate DOCX” action.

In order to allow user to edit attachments added to the document it is needed to configure the website and name with the attachment library. If the target library doesn’t exist just create new from any location. Attachment library has to be a normal document library and is common for all the processes.

In Webcon BPS Word Add-in can you can compare different versions of the same file so by adding attachments to the form use the “Overwrite” option.

After installation and launch of the Word Add-In a new tab „WEBCON BPS” will appear. Click on it and following buttons will be displayed:



First three options: „Version history”, „Show changes”, “Element information” are available only when editing the Word document which is attached to a specific form. In order to edit it, click on the attachment with right mouse button and choose “edit file”. To edit attachments users have to have privileges for modifying without deletion.

When opening the document from a different source these options are unavailable.


Version history
