Freeze Panes in BEX WAD

Hi Experts,

I would like to freeze panes in columns in SAP WAD, for that I used the modification module com.sap.ip.bi.rig.Scrolling.

However, I couldn't have a control on how many columns I want to freeze (may be I don't know)

Assume that I have a query output with columns as below

A B C D E F

Here, in the query, A,B and C fields are in rows. D, E and F belongs to key figure structure.

Using the above module, freezing of panes is done till column C. (Only I can able to freeze A, B and C columns).

My requirement would be to freeze columns till E, where D and E are in the columns of the query.

Is there any parameters I need to specify to freeze columns till E in WAD.

Kindly suggest on how to achieve this.

Br, H
