Instead of using a string variable, create a multiline input parameter. You can then use it as you would a regular variable, concatenating text onto it, without running into problems.
Be aware that not all workflow actions can handle strings longer than 255 characters.

The limitation on storage size for any SharePoint 2013 workflow variable is 256KB, so you should have about a 64,000 UTF-8 character limit (not tested).
Is this possible within a SharePoint 2013 Visual Studio Workflow? I attempted to use the SPFieldMultiLineText type and I could not deploy the workflow. I even attempted to build a custom workflow activity that returned a SPFieldMultiLineText value. It would not let me deploy the workflow. Thanks for your ideas/thoughts.
ReplyDeleteCan you please explain what is a Multiline Input Parameter? Is this a variable type like string? How and where to find this type in Visual Studio workflow? Please explain.
ReplyDeleteLooks like doing REST calls doesn't support > 255 characters with this technique either...
ReplyDeleteThis rocked, thank you
