Hi,
I'm trying to define a Picklist for the user for selecting one of his own, non system, cubes.
I know, I find the names in the }Cubes dimension. But there are also all system cubes, beginning with "}".
Now I want to create a subset with all non }-cubes using a MDX statement.
Unfortunatly I didn't get a solution.

TM1FILTERBYPATTERN is filtering positive, so anything like '}*' will be in, but I need the others!

Code: Select all

FILTER( {TM1SUBSETALL( [}Cubes] )}, NOT StrToMember([}Cubes].CurrentMember.Name).StartsWith("}") )

leads to an error, maybe StartsWith is unknown? I could not find the TM1 list of MDX statements for string handling.

BTW:

Code: Select all

FILTER( {TM1SUBSETALL( [}Cubes] )},  [}Cubes].CurrentMember.Name = '}Cubes' )

is syntactically correct.

Also my attempt to use SUBSTRING() was unsuccessful. I read an article for defining a rule doing the SubString there, but I can't believe that this would be the solution today.

So any hints for me?

After searching for hours and posting this question, I fould the magic "EXCEPT".

Code: Select all

{ EXCEPT(
{ TM1SUBSETALL( [}Cubes] )},
{ TM1FILTERBYPATTERN( {TM1SUBSETALL( [}Cubes] )}, "}*") }
)}

Worked for me. But if anybody else will face this problem in the future again, here is the code.

Another option for you loosely based on your first example and using INSTR:

Code: Select all

FILTER(
	{ TM1SUBSETALL( [}Cubes] )},
	INSTR(1,[}Cubes].[}Cubes].CurrentMember.Name,"}",1)=0
	)
