Hello Forum,

I've got the problem that my number of obs. differs every time I run my Do-Files (generation of data (by merge) and variables, casewise deletion) about +/- 5 cases. The results of merging seem to be the same every time so I don't think that the problem is related to this process. Does anyone have an idea?
Note: since I'm using a remote version with high standards of data protection I'm not able to post the syntax. But maybe, someone has an idea.

Thank's a lot
Johannes
