Structure THEADVB for creating texts

Hello,

is here some experience to create texts via the structure THEADVB? In my case I want to use it in function module SD_INVOICE_RELEASE_TO_ACCOUNT.

After reading some documents on internet I understand that the field TDTXTLINES needs to include the number of text lines which need to be stored into a table of the structure TLINE.

But where inside the structure THEADVB I do have to communicate the name of the internal table which includes the real text information? The function module had not been documented in English or German.

Is there any knowledge available?

Thank you

Norbert
