I am working with Linde Engineering India (Linde AG) as Engineering consultant. Our daily routine job is to review various suppliers' documentation to meet the client requirement. Supplier submits the document which we review in .pdf using commenting tool. Previously we were using Acrobat 9 for this in Windows7. Now we are using Windows 10 for last more than 1 year and in that, we are only allowed to use Acrobat standard DC Version 2015.006.30033. In this Adobe Acrobat version, we are not able to edit the comments made by our peers / sub-ordinates before sending it back to Supplier easily. For this, we need to unlock each and every comments everytime for editing as well as for moving it to proper place on the document so that the information behind the comment block can be read by the next reviewer clearly. This is consuming a *** lot of time of us which is tedious and not desirable in this digitalized world. We shall have flexibility for the same so that we can work easily. For example, if I have received one supplier document which I have to send it to 3 other engineers for their review. When first reviewer comments, he himself can not edit the comments after some time of commenting or after saving the document some time. Secondly, the second/third reviewer also can not review the complete document as the previous reviewer's comments were locked and not movable so that the information beneath/behind the comment box can not be reviewed. Finally, when that document comes to me after completing the review cycle, my task is to consolidate the comments, arrange the comments and place it appropriately, and rephrase the comments clearly so that Supplier can understand the query/intension of those comments to move faster and resolve the issues. For doing so, I have to unlock each and every comment box every time (our one document can have more that hundreds or some times thousands of the comments). Now, please imagine the amount of work increased at our end. We are very tight with the schedule and we can not used Adobe. We need immediate attention and support from Adobe/Acrobat so that we can use this tool without above explained problem. Your positive and urgent/timely response will be highly appreciated. ALSO PROVIDE THE REQUIRED PLUG_IN OR UPDATE to be run in the same version of pdf which is referred in this description above.
