Error in expression

[Guan_Achinech]

Hello All

I wonder if you guys would be able to help me with this expression which seems to  be wrong:

count( distinct{ 1 < [SALES ORDER NUMBER]=P([SALES ORDER NUMBER]), article={*}-P(article) >} [SALES ORDER NUMBER])

Would you kindly help me to check if is it there any mistake?

Thanks

Can you share sample data or app? I am sure lot of experts over here can help better once we have something to try with - 

In the 2nd part are you trying to fetch the excluded articles, something like this may be, not sure though, haven't used them for a long time..

count({1<[SALES ORDER NUMBER]= P([SALES ORDER NUMBER]),article=E(article)>} distinct [SALES ORDER NUMBER])

You can perhaps get rid of the syntactical error by putting quotes around *, like:

count( distinct{ 1 < [SALES ORDER NUMBER]=P([SALES ORDER NUMBER]), article={"*"}-P(article) >} [SALES ORDER NUMBER])

Also, try to simplify the expression by replacing article={"*"}-P(article) with article=e(article). This should work unless null values are your concern.

Hey guys 
thanks a lot for the tips!
I just figured out by modifying the measure field and it works.
