i've an overview session, it contains, BP details(tccom100) and BP address details(tccom130), i also want other details like sold-to,ship-to, invoice-to,etc, which i am taking from table tccom133, but in overview session only details from tccom100 and tccom130 are displaying, but the fields are added in DFE, how to display these information.

Dear Charles,

As you mentioned the session is based on tccom100 and you want to display some other data from different tables.

You have to add the fields you want to see on the form with "Field Type" as "Display". (declare the fields in script as extern domain if variables)

Then you need to get the values for those fields in the script.

You can write the function to fetch the values for those new fields on respective field's before.display: section
Or you can try to call the function on after.field: of tccom100.bpid

Thanks & Regards
