There are identical sub-expressions to the left and to the right of the "foo" operator (IdenticalExpressions)

Type	Scope	Severity	Activated by default	Minutes to fix	Tags
Error	BSL OS	Major	Yes	5	suspicious

Parameters

Name	Type	Description	Default value
popularDivisors	String	There are popular division operations used for quantification (e.g. 60 or 1024 for time and bytes). Use comma-separated values which'll be ignored on both sides of division operation	60, 1024

Description

The analyzer found a code fragment that most probably has a logic error. There is an operator (, <=, >=, =, <>, AND, OR, -, /) in the program text to the left and to the right of which there are identical subexpressions.

Examples

If Summ <> 0 AND Summ <> 0 Then

    // TODO

EndIf;

In this case, the AND operator is surrounded by identical subexpressions Summ <> 0 and it allows us to detect an error made through inattention. The correct code that will not look suspicious to the analyzer looks in the following way:

If Summ <> 0 AND SummNDS <> 0 Then

    // TODO

EndIf;

OR

If Summ <> 0 Then

    // TODO

EndIf;
