Hi All,

I use sap netweaver 7.0 abap trial version, recently and i meet some problem to create Transformation between Datasource and InfoObject .

Log Detail:

Short text of error message:

Network could not be launched due to control error

Long Text of error message:

Diagnosis

Network control cannot be started either because is is not installed on the front-end compouter, or because the control framework is inconsistent when the function is called up.

To be able to start the network graphic, you need two OCX files that delivered with the BW frontend.

Question:

Where can I found those files?

Is somone meet this problem?

If i found it how i do to install ?

Please Help me !!!!
