Buffering points in QGIS, and dissolving to make a single feature for each buffer that touches

Question

I am trying to buffer points then dissolve to a multipart feature for each, but keeping all associated attributes of one of the buffered points (any one). GDAL gives me the following error with GDAL buffer:

Warning 1: Value 234000018 of field LNRFTRD of feature 0 not successfully written. Possibly due to too larger number with respect to field width.

So I tried the native QGIS buffer, then dissolved the buffers; however, it made all buffers a single feature. I would like the attributes from one of the buffered points associated with each new dissolved feature.

Answer 1

1. Buffer
2. Dissolve
3. Multipart to singleparts
4. Refactor fields to drop all fields (load the fields from template input point layer, then delete all)
5. Join attributes by location to join point data to the buffers (Take attributes from the first matching feature only ...)
