How can I create a relationship for new points connected to lines in ArcSDE?

Hello ,

i would like to insert some new points into ArcSDE, where each point will be positioned on and connected to various lines.

How can I establish a relationship between each point and its corresponding connecting lines?

Is it possible to set up this relationship in FME, so I can view the relationship class later in ArcMap?

there is already a relationship exist between feature class lines and feature class points.

But what  about the new points from FME?

Could anyone advise me on a solution?

Thanks in advance .
