How to Display long Texts in BI Explorer

Dear all,

I'm working with BI 7.0 BEx Explorer and I need to display long text (over 200 char) managed with R/3 sapscript.

I Extract full field by the Function Module "READ_TEXT" but no so as to bring BI.

The only idea that comes to mind is to break the full text mapping in n infoobject mapped in each of their 60 long-char (1 .. 60 - 61 .. 120 - 121 .. 180, and so on...), but in the query result is not quite clear...

Do you have any idea?

Thank you,

Alberto
