SUMMING command in SAPScript

Hello gurus,

I am trying to use the SUMMING command in SAPScript to output a total on each page of a transfer order.

According to the sap help, I need to declare the summing total variable within the print program using the TABLES statement, I'm trying to total LTAP-VSOLA so should I be declaring a table of this type? ANd if so, shouldn't I be using a DATA statement for this? I'm confused as to what the help actually means?

Has anyone used this statement before and have an example that I can see?

Thanks,

Ruby
