Email content text dynamic number of text lines

Hi all,

I need to send texts in email contents but without knowing there will be how many lines of text.

Example below:

depending on selection screen how many variants user choose to run for report S_ALR_87012052, i need to output the x number of lines.

If user choose to run 2 variants of S_ALR_87012052,

the contents should be: with the &X& depending on a table list.

So how do I do it? in So10 or in abap program itself? anyone got sample code for this?

Spool number for S_ALR_87012052 - Asset Retirements Listing = &X&

Spool number for S_ALR_87012052 - Asset Retirements Listing = &X&
