Update Talent Management Infotype - Education, Career, Accomplishment

Hi freinds,

I got a requirement to update Talent management infotypes (7402/03/04/05/06/07) from portal in a custom webdynpro application. Can you provide any info on updating, as we are having text fields(>1000 character) for each infotype. How can integrate text field along with HRP740x tables and update them?

Thanks,
