There could be a few potential causes of an error in the calculation of multidimensional expressions (MDX) in an SSAS cube that is unidentified, including:
Syntax errors: Incorrect syntax in the MDX query can cause errors. It is essential to ensure that the syntax is correctly written, including parentheses, commas, quotes, and other symbols.
Invalid expressions: MDX queries can have complex expressions, and if even one expression in the query is invalid, it can cause the whole query to fail. Therefore, it is necessary to check for invalid expressions and correct them to ensure successful execution.
Referential errors: When using MDX queries, it is essential to reference valid objects such as dimensions, hierarchies, attributes, and measure groups. If a reference is invalid or has changed, the MDX query may also fail.
Data inconsistency: Data inconsistency is another possible cause of an error in MDX calculations. For instance, when there are inconsistent data types, formats or values in the cube, it can affect the calculations.
Memory limitations: Sometimes, when creating or executing an MDX query, the amount of memory utilized may exceed memory capacity. This may cause system crashes or errors, leading to an unsuccessful calculation.
To eliminate these errors or prevent them from occurring, it is recommended that individuals double-check the syntax of MDX queries, validate expressions, reference objects correctly, maintain data consistency, and increase system or memory capacity if necessary.
