Hi, any help is welcome�?� I need to split some lines where it intersects with points. I used the Split Lines at Points but the output is not what I expected. Thanks in advanced!!

Your post is completely vague. What did you expect that you did not get? A picture of what you got and comments on what you don't like would help a lot.

Sorry for not been so clear. Basically I have two Feature Classes, one for points and one for liens. Some points intersect the lines. I want to run a script or tool that splits the line wherever the point intersects the lines (like valves on top of mains). I have tried the Split Lines at Points but it does not split the lines wherever the point intersect the lines.[ATTACH=CONFIG]24369[/ATTACH]

So you have an Advanced license, which is good, since that gives you the most options.
What was the search radius setting that you used? Not specifying a radius would probably require eseentially perfect alignment of your points and lines, and nearly invisible imperfections in the alignment would result in lines not splitting. You may also want to make a copy of your data and run the Integrate tool first to ensure the lines and points are fully snapped before trying the Split Lina at Point tool.

Will the tool actually split the line at every single location where it intersects with a point?

The Integrate tool won't split the line at all, it just aligns the features, but it is one of the few tools that directly alters the source data without creating a new output. That is why it is important to run Integrate on a copy of your data, so that you have your original as a backup if you configured the Integrate tool incorrectly.
The Split Line at Point should split every line at every overlapping point if the overlap is within the search radius in a new feature class, but it won't alter the original line file. If you are expecting the original line file to be altered, you cannot use that tool to do that directly. You can only create a new output file and replace the original file with it. However, it would be wiser to rename the original unsplit line file and keep it as a backup and then change the name of the split line output to take the place of the original lines rather than completely destroy the original unsplit lines (at least until you are absolutely positive the new lines are perfect and all that you will ever need going forward). Only rarely do geoprocessing tools operate to make changes directly on the original source data itself, since, if any mistake was made in the set up or use of such tools, data recovery would be very difficult if not impossible.
