What does this code mean

[n1ef5ng1]

=if( MonthEnd ( MAX( Date ) ) <> var_EndDate AND MonthEnd( MAX ( Date ) )
= MonthEnd( var_EndDate ) ,
Sum( IF(Derived_Status <> 'LRSHP', TEU,0)) / Day( var_EndDate ) * Day(MonthEnd( MAX ( Date ) )) ,
sum( IF(Derived_Status <> 'LRSHP', TEU,0) ))

This code above is trying to compute the latest month data to be EXTRAPOLATED with a certain formula, else it will just display the value. However the value that it compute have only one condition which is Derived Status <> LRSHP

However, I would like to reuse this code and use to compute the sum with three condition as pasted below, I tried to use

=if( MonthEnd ( MAX( Date ) ) <> var_EndDate AND MonthEnd( MAX ( Date ) )

= MonthEnd( var_EndDate ) ,

Sum( IF(Derived_Status = TSHIP and Container_Class_Name = Empty and Unlocode_Port_Of_Loading = 'ID*', TEU,0)) / Day( var_EndDate ) * Day(MonthEnd( MAX ( Date ) )) ,

Sum( IF(Derived_Status = TSHIP and Container_Class_Name = Empty and Unlocode_Port_Of_Loading = 'ID*', TEU,0))

but no value was compute.

any help in this

Few errors in ur expression;

1) use ' ' : Derived_Status = 'TSHIP' and Container_Class_Name = 'Empty'

2) use wildmatch:
wildmatch(Unlocode_Port_Of_Loading, 'ID*')

3) missing ) at the end :

so correct expression:

=if( MonthEnd ( MAX( Date ) ) <> var_EndDate AND MonthEnd( MAX ( Date ) )

= MonthEnd( var_EndDate ) ,

Sum( IF(Derived_Status = 'TSHIP' and Container_Class_Name = 'Empty' and wildmatch(Unlocode_Port_Of_Loading, 'ID*'), TEU,0)) / Day( var_EndDate ) * Day(MonthEnd( MAX ( Date ) )) ,

Sum( IF(Derived_Status = 'TSHIP' and Container_Class_Name = 'Empty' and wildmatch(Unlocode_Port_Of_Loading, 'ID*'), TEU,0)))
