Hi Sachin,
Thanks for your help. Earlier my perform---endperform in my sapscript is not triggered because it change in the the word type editor. It haves double /: as I manualy key in the /: as well since that symbol is not displayed in the word type editor.
However, the program gives abap dump as the parameter passing seems wrong. The error message given was "&symbol not found" .
I dont know where to declare the variable in a sapscript as it seems only variable &PAGE& is allowed here.
Anyway, the solution offered my nabheet madan seems to work nicely in my case here.
Thanks again!
