Please share ideas for entering additional information when making revisions

Hi,

I am a beginner who can write Java and C ++ code but don't know how to apply development in PDMLink.

PDMLink OOTB does not allow any additional information to be entered when proceeding with a revision.

If you have a development case that allows you to enter additional information when making revisions or an example where you can add editable properties to EPMDocuments without check out, please share it.

If I have to develop, please tell me what part of Customization Guide can help.

Thanks, 
Warm Regards,

SeonHo Cha
