Hi All, 

I have multiples polygon files and points file. Multiple points falls into the single polygon. I want to join the polygon to points, which will create a new attribute where the row of polygon attribute will be remain same but the column will increase based on point falling falling into single polygon. Now i am using the Spatial join tool in ArcGIS 10.3 but its creating the duplicate polygon based on the number. 

Now, how should i join two files, where in the ploygon attribute row will be same but only column will be increased based on the points falling into the same ploygon using arcgis 10.3.

Are you trying to count the number of points within each polygon?

A spatial join of the polygons to the points should give you a table which can then be summarised by the polygon id (whatever that might be).

Are the polygons all separate with no overlaps? If they do overlap, you may need to Union the polygons first.

Hi @Neil , thanks, No i am not trying to count the points and there is no overlap in the polygon.

I have one of polygon file which contains 3 percels and one point file which contains multiples points. And that multiples points fall into different polygons, i want to join the multiple polygon with points fall into same polygon. If i use the Spatial join than if suppose i have 5 points fall into the one polygon then its created 5 same polygon in the ploygon's attribute.  but i want to keep the polygon no constant where only column will be increased depend on the falling points. How to do it.

Sounds like you need to do a screen grab to show your situation. It is hard to tell from your description whether the polygons overlap or not.  If they do, then it may be worthwhile intersecting/unioning them so that you end up with a unique non-overlapping landscape first
