sort text internale table

hi guys,

now i have an internal table with a field of 10 character type length, i need to sort by this field descending and its value could be numeric or character.

this is order i want ‘TR’‘10’‘9’, for example,

this the order i got now ‘TR’‘9’‘10’, 'cause by byte compare 9 is greater that 1.

so how to sort this kind of table, is there any FM?

thanks
