I would like to ask a question about an issue that i need your help to success it 
Firstly, assume that , I have a text like " Request the maintenance to perform at an object "
I want to shorten this sentence to "REMAINTIPERFAOBJ" otomatically. --> The length of this Word must be 16 or less.
How can i do that on ABAP ?
Is there anybody can tell me the method ?
P.S : I just want to create a smart code according to long text. Then, i'll insert this short text to Z table.
