Hi:
Just a guess. ACCT has a length of $5 or $6??? When you use this technique to put special text at the break, you are limited to the length of the variable on the left-hand side of the = sign.
You may find the answer in this Advanced Proc Report Topics paper:

...or one of the techniques is shown here:

There are several other methods for addressing this length limitation with PROC REPORT (user-defined format, changing the length of the original variable). If you have an immediate need, you could contact Tech Support for help with any of these techniques.
