word wrap

Hi,

I have written my logic in the following way in my print program:

w_sernr type string.

CONCATENATE w_sernr t_sernr-sernr INTO

w_sernr SEPARATED BY ', '.

But though 17 serial numbers are there while printing the line crosses the paper size...so not printing all the sernr....

Can any one suggest me how to make the line devided so that this will work as word wrap?

Definitely reward points will be given 😊
