How to fix an issue within the Structural Parent Tree for Accessiblilty

Looking for help: My PDF passed the Acrobat Accessibilty test but is not passing the PAC3 test for the following reasons which all fall within the Structural Parent Tree Section under the basic requriements (ISO 32000-1):

- Entry for given MCID missing

- Inconsistent entry found

There are several errors for each of these problems and when you click on the individual item, such as entry for given "MCID" missing, it doesn't show where the problem is occuring in the document like it usually does. In other words, typically when you click on an issue is points to where the problem is occuring. In this case it is just blank. How can I get rid of this issue so that the document passes?

Thanks so much!

Did you open the Results in Detail window in PAC 3? It's the top button in the lower left.

Only that windows takes you to the actual problem item.

I've run into the Inconsistent Entry error a couple of times. After much trial and error, I think a found a fix - it is kinda goofy and I'm not sure it always works, but it worked for me both times. 

In the Page Thumbnails pane, select all the pages and Extract Pages as Seperate Files. Open the first page, then back in the Page Thumbnails pane, add all the other pages back in. Somehow deconstructing then reconstructing the PDF fixed the mystereous Inconsistent Entry error. 

Re. the "Entry for given MCID missing" error - I don't recall running into that one. Maybe cross your fingers and try this ...

  • Tools - Print Production - Preflight.
  • Make sure Acrobat Pro DC 2015 Profiles is selected in the Libraries window at the top
  • Select the "Make individual corrections" tool (the wrench icon).
  • Enter StructElem in the search field and carry out the correction "Insert missing Type entry in StructElem objects".

No need to extract the PDF into separate files. That will cause more problems with internal hyperlinks, cross references, tables of content, and the overall tag tree itself.

 

Just run the Preflight steps mentioned above.

 

But remember that this is a band-aid. Best to figure out what you're doing wrong in InDesign. Usually it stems from incorrectly threaded story frames, inconsistent use of Paragraph Styles, and basic poor construction methods in InDesign.

@Bevi Chagnon - PubCom I'm having this issue and Preflight didn't fix it. As the OP stated, the Results in Detail pane doesn't show where the error is (screenshot attached). What can I do to locate the errors? This is a large document that passed all other criteria. Thank you.

There are third-party tools that allow you to "Rebuild" the structural parent tree. Unfortunately, I have yet to find a solid solution using Acrobat alone.
