Error Cannot open Data Explorer Invalid argument; check vor vulnerable character or character ...

[Former Member]

In a very simple calculation-view I can not preview the projection-node selectPositions.

I get the error message: "Error" "Cannot open Data Explorer" "Invalid argument; check for vulnerable character sequence."

All other nodes I can preview. Except this one.

I can also Preview other Projection Nodes of tables within the same schema.

There was probably the same issue already

Unfortunately there was no solution and the thread is archived and I can't post there.

What is recorded in the indexserver when this error is generated?

Also I see you have named the views "select". You cannot use SQL keywords while naming views in the HANA modeler, its a design limitation.

See SAP Note 2487226.....a simple search got me this.

Thanks Michael Healy,

I renamed the projection node "selectPositions" to "sel_Positions".

From that point on the data preview works on this node 🙂
