field catlog Upper case

Hi,

I am creating the dynamic fieldcatlog in ALV. here When you are creting for some fields having the Lower case letters, because of that report is giving the dump.

I Know all fieldcatlog fieldnames should be in the UPPERCASE.

but I am getting some field heading in lower case. is there any option to make all fieldname in UPPER CASE even though dynamic field name in Lowercase.

regards,

Ajay
