It kind of looks like from that picture that the label has a space in it. That will not work well as a variable name. Either it will be invalid, or it you set the VALIDVARNAME option to ANY then it will require that you use a name literal to reference it. I would suggest either replacing the space with an underscore or using CaMeL case to mark the starts of new words in the name.
And to the general case a label can be up to 256 bytes long and a name can only be up to 32 bytes long. So you cannot always use the label as a name.
If you do want to change the name use the RENAME statement (or perhaps the RENAME= dataset option).
If you want to change the label use the LABEL statement.
data want;
set have;
rename ibesname=CompanyName ;
label ibesname='IBES Name' ;
run;
