Error "The depth of the expression tree 200 is larger than the max depth 200 allowed." is received when creating a security filter in Command Manager 9.4.1

SYMPTOM:
Error "The depth of the expression tree 200 is larger than the max depth 200 allowed." is received when creating a security filter in Command Manager 9.4.1.


(The depth of the expression tree 200 is larger than the max depth 200 allowed. 



Node cannot be deleted becaused it has 3 children, and ReplaceWithChild parameter was set to 'True'.)

CAUSE:
This is working by design, as currently the max depth of an expression allowed is 200 in Command Manager 9.4.1. If the expression is too deep, Intelligence Server may crash by exhausting the stack space.

ACTION:
An expression with less depth is suggested. Adding some parenthesis to change the grouping of the parsed expression can decrease the depth, as below picture shown:


CREATE SECURITY FILTER "xxx" DESCRIPTION "xxx"  IN PROJECT "xxx" EXPRESSION “((Customer@ID=2 …)AND(Customer@ID=2 …)) AND ((Customer@ID=2 …) AND (Customer@ID=2 …))”;
