Hi Ntuthuko,
I guess you're asking how to evaluate in your microflow if your attribute has a certain value from an enumeration.
I guess there are three things good to know, if you have a attribute with an enumeration you can just compare it as:
$MyEntity/EnumAttribute = MyModule.Enumeration_Level.Value1
If you would like to compare a string value against an enumeration value then you have 2 possibilities, you can compare to the caption like this:
getCaption($MyEntity/EnumAttribute)
or against the value with:
getKey($myEntity/EnumAttribute)
You also could compare a string value straight to an enumeration value.
