Does anyone know how capture all the line items (From the comments field) listed in the screenshot below? I want to use the captured data as a variable to update another field (wf-comments-accumulated).
Thanks in advance.
it's actually a view on field's version history track.
to get all the entries from version history you will need to make a webservice call - Lists.GetVersionCollection Method (Lists)
then I'm affraid of there is no other easy way.
what about web request action, do you have it disabled as well?
it might a bit more difficult to configure it, but it should do moreless the same
apart from from web call/request I would say it might be achievable with some powershell script, but you would need to install 3rd party action into your environment.
lastly, you coukd develop your own workflow action for that purpose.
