The intention is to expose MDX commands that work in TM1, their syntax or usage and some examples or applications.
This is a guide and not gospel - I am sure there are many ways of doing the same thing as well as better ways.
You will see that some examples switch around certain functions - this may be by design or accidental.
There are also gaps as this project is a work in progress. Similarly, alignment of syntax needs to be reviewed and edited.
Most importantly was getting something out here to begin with. Just like with any TM1 model, something is better than nothing.
Expect errors and omissions but please feedback so that I can update/correct for everyone's benefit.
I am not going to try and replicate any websites or MDX books of which there are many.
My go-to reference is Multidimensional Expressions (MDX) Reference - SQL Server 2012 Books Online, Microsoft
My examples are based on a simple model with an Expense cube built with a Period, Cost Centre and other dimensions.
My Period dimension is deliberately designed with leaf elements as YYYY-MMM e.g. 2021-JAN - these do not sort chronologically and is perfect for some examples.
Also, I have assumed a July start or Period 1.
My Period dimension has multiple rollups grouping Periods into Fiscal Years as well as Periods into Quarters, Halves and Fiscal Years.
These have also been configured in the }HierarchyProperties cube to drive some of the Level queries.
You can create your own Period dimension per below to play with the examples.

- }HierarchyProperties-Default.png (13.39 KiB) Viewed 37326 times
You can configure your own dimension accordingly to test some of the examples.
I also created a basic Client Assumption cube to read the Current Period for the user in some examples.
You could create this per the below cube view.

ARITHMETIC OPERATORS
| + Add, Positive |
| / Divide |
| * Multiply |
| - Subtract, Negative |
| ^ (Power) |
BITWISE OPERATORS
| AND | Performs a logical conjunction on two numeric expressions. | <Expression 1> AND <Expression 2> | { FILTER( {TM1SUBSETALL( [Cost Centre] )}, [Cost Centre].CurrentMember.Properties("Primary Cost Centre") <> "" AND [Cost Centre].CurrentMember.Properties("Division") <> "" ) } Should give you Cost Centres where there is both a value in the Primary Cost Centre and Division attributes. |
| NOT | Performs a logical negation on a numeric expression. | NOT <Expression 1> | { FILTER( {TM1SUBSETALL( [Cost Centre] )}, NOT [Cost Centre].CurrentMember.Properties("Primary Cost Centre") <> "" AND [Cost Centre].CurrentMember.Properties("Division") <> "" ) } Should give you Cost Centres where the Primary Cost Centre attribute is blank and Division attributes is not blank. |
| OR | Performs a logical disjunction on two numeric expressions. | <Expression 1> OR <Expression 2> | { FILTER( {TM1SUBSETALL( [Cost Centre] )}, [Cost Centre].CurrentMember.Properties("Primary Cost Centre") = "" OR [Cost Centre].CurrentMember.Properties("Division") = "" ) } Should give you Cost Centres where Primary Cost Centre, Division attributes or both are blank. |
| XOR | Performs a logical exclusion on two numeric expressions. Returns True when only one expression evaluates to True. Either Expression 1 or Expression 2 is True, not both. | <Expression 1> XOR <Expression 2> | { FILTER( {TM1SUBSETALL( [Cost Centre] )}, [Cost Centre].CurrentMember.Properties("Primary Cost Centre") = "" XOR [Cost Centre].CurrentMember.Properties("Division") = "" ) } Should give you Cost Centres where either the Primary Cost Centre or the Division attributes are blank, but not both. |
| IS | Performs a logical comparison on two object expressions. Use square brackets if your level contains a space e.g. [Fiscal Year] Best to fully qualify using dimension and value e.g. [Period].[Quarters] where the name may appear in other dimensions causing ambiguity. | <Expression 1> IS (<Expression 2> | NULL ) | FILTER({TM1SUBSETALL( [Period] )}, [Period].CurrentMember.Level IS [Period].[Quarters]) Gives you Periods linked to the same level as which Quarters was defined. |
COMPARISON OPERATORS

| <= | Is Less Than or Equal To | <Expression 1> <= <Expression 2> | { FILTER( {TM1SUBSETALL( [Cost Centre] )}, [Expense].(...,[Amount]) <= 0 ) } Returns a set of Cost Centres where specified value in the Expense cube is zero or negative. |
| TRUE | Not an operator but a literal used in comparisons/filters | ||
| FALSE | Not an operator but a literal used in comparisons/filters |
CONCATENATION OPERATORS
| + | Combine or join multiple strings | <String 1> + <String 2> | {StrToMember("[Period].[Period].[" + [Client Assumption].( StrToMember("[}Clients].[" + UserName + "]"), [Client Assumption Measures].[Current Period]) + "]")} Concatenates the value from an assumptions cube with the hierarchy to create a valid member. |
SET OPERATORS
| - (Except) | Returns the difference between two sets, removing duplicate members. This operator is functionally equivalent to the Except function. | <set expression 1> - <set expression 2> | Did not work in a Dimension set but may work with a SELECT statement |
| * (Crossjoin) | Returns the cross product of two sets. This operator is functionally equivalent to the Crossjoin function. Used in an MDX view where you have dimensions stacked e.g. Product within Customer. | <set expression 1> * <set expression 2> | SELECT {TM1SubsetToSet([Expense Measures].[Expense Measures],"Default","public")} ON 0, {TM1SubsetToSet([Cost Centre].[Cost Centre],"Default","public")} * {TM1SubsetToSet([Reporting Currency].[Reporting Currency],"Default","public")} ON 1 FROM [Expense] WHERE ... |
| : (Range) | Returns a naturally ordered set, with the two specified members as endpoints and all members between the two specified members included as members of the set. | <Member 1> : <Member 2> | [Period].[Period].[2021-JAN] : [Period].[Period].[2021-DEC] Should return periods from Jan to Dec |
| + (Union) | Returns a union of two sets, excluding duplicate members. | <set expression 1> + <set expression 2> | {[Period].[Period].[2020-JAN] : [Period].[Period].[2020-DEC]} + {[Period].[Period].[2022-JAN] : [Period].[Period].[2022-DEC]} Will return a set with the range of members from the first expression and second expression.

Values are enclosed in square brackets. | <Member expression>.UniqueName | FILTER({TM1SUBSETALL( [Period] )}, INSTR(1, [Period].CurrentMember.UniqueName, "^", 0) = 0) Returns members that are unique in the hierarchy i.e. do not form part of any other rollups and thus are not further qualified with a caret (^) |
| Properties | Returns a string, or a strongly-typed value, that contains a member property value i.e. Attribute value. | Member_Expression.Properties(Property_Name [, TYPED]) | {ORDER( {TM1FILTERBYLEVEL( {TM1SUBSETALL( [Period] )}, 0)}, [Period].CurrentMember.Properties("Month"), BASC)} Returns a set of leaf level months orders by Month which is numeric. 2021-JAN, 2021-FEB etc. do not sort chronologically naturally. |

NB: 4th parameter, compare in TM1 is used as 0 for case-sensitive, 1 for ignore case. | InStr([start, ]searched_string, search_string[, compare]) | {FILTER( {[Period].[Period].Members}, InStr(1, [Period].[Period].CurrentMember.Name, "ju",1)>0 )} Returns periods containing JU, Ju, jU or ju - remember parameter 4 to manage case. |
