requirement

Hi All,

I have a requirement

table:

Load* Inline

[Region Sales

S, 200

N,

E, 400

W,

];

Now the requirement is

In Null values, should be replaced by previous sales.(Sales for N 200 and for W 400)

How do we achieve this?

any ideas?

Regards,

Bob Tech

Thanks for your quik reply.

Yes that is exactly what I need.. and if you don't mine could you elaborate your expression as am new to qvw.

  

what exactly does len(trim(sales)?

As I know know Len('qlikview') it returns 8.
