Append original (source) Feature ID to undissolved Buffer attribute table

Question

Hi,

1) I have a bunch of source polygons for which I  have created undissolved buffer polygons.
2) I then want to do some calculations, e.g. length of line insecting the polygons, and add that information to the buffer attribute table
3) I then want to join those calculations to the source polygon

However, the feature ID of the source polygon is not appended to the attribute table of the buffer so this makes step 3 very difficult.  I thought a spatial join would be a workaround but I couldn't get it to work.

Does anyone have any idea how might achieve step 3 above?

Thanks,
Garret
BTW: there is a column called ORIG_FID in the buffer attribute table where I expected the FID of the source feature, but it is equal to one in all rows

When I try to upload, I get this:

Request Entity Too Large
The requested resource
/newattachment.php
does not allow request data with POST requests, or the amount of data provided in the request exceeds the capacity limit.

Even though the LPK file is only 2.2 MB, 10 MB is the limit

An easy way to share data is to use the Package Layer (management) tool to convert your feature class/layer to a file that you can email or upload.

I'm glad that you've found a workaround, but if you can provide your data I would still like to investigate the problem.

Hi Drew,

Your response helped a lot.  Since you couldn't reproduce the error, the problem was with the input data.  So there's no bug (!)

First I tried Repair Geometry; no change.

Then I exported the Feature Class to a shapefile, tried Multiple Ring Buffer again on the shapefile and hey presto! the input feature attributes were appended to the buffer attribute table.

Not sure how I can send you the Feature Class as it's embedded within a geodatabase.

Thanks,
