Modify the text of a data field on the screen

Hi,

I am looking to change the text of a SAP data field on the display screen for an infotype 106. I have the required object key for it. When I entered the key it logged me successfully, however it displayed a message that I am not authroized for changes. Infact as a developer my user profile has the highest authroization level 'SAP_ALL'.

I am looking to modify the module pool MP010600 and screen number 0100 on the infotype screen 106.

It displays the message:

"you have no authroizations for the authroization object 'S_DEVELOP' which would allow you to change the screen'. I checked with the admin guy. He did not have a clue either. Am I missing something?

Any thoughts how to resolve it?

It would be very helpful.

Thanks in advance,

VG
