BEx transport request '' is not available or not suitable

Hi Experts,

While I am trying to execute standard query. The followimg message getting displayed.

Diagnosis

There are the following possible causes:

No request has been set up as the standard transport request for BEx objects.

The (set up) request '' (for the package '' ) has already been released.

The (set up) request '' (for the package '' ) is not of the type 'transportable change request'.

System response

The request can not be used to record changes to BEx objects (queries or Excel workbooks). The changes made to objects you are editing will not be logged.

Procedure

If you want to record changes to BEx objects, set up an open transportable change request as the transport request for BEx objects. (If the package '' is not empty, set up a request for this package).

Inform your system administrator of your actions, or enter a new, targeted transport request in the Administrator Workbench in the transport connection by using the 'BEx' pushbutton (Create Transport Requests for BEx).

Procedure for System Administration

Can anyone give the inputs for this

Regards

Kumar
