ALV Using FM

Hello,

I have created one report using ALV Function Modules.

I followed all these steps for uploading Logo :-:

1.  Goto the transaction OAER

2.  Enter the class name as 'PICTURES'

3.  Enter the class type as 'OT'

4.  Enter the object key as the name of the logo you wish to give

5.  Execute

6.  Then in the new screen select Standard doc. types in bottom window

     Click on the Screen icon

     Now, it will ask for the file path where you have to upload the logo

7.  Now you can use this logo in REUSE_ALV_COMMENTARY_WRITE

And displayed using FM....

CALL FUNCTION 'REUSE_ALV_COMMENTARY_WRITE'

     EXPORTING

       it_list_commentary = lt_header

       i_logo                    = 'MYLOGO'.

When logo is uploaded, in OAER transaction default logo size is 819 X 460 px.

Same size appears in report.

How to re-size the image/logo ????
