I have created a compute field named x of type text.I used ah field y in compute expression which is of numeric .Basically i want to output to be 'y'+"some text" which would be used as dimension.But the Dataflow fails saying Incompatible types: NUMERIC and STRING .How to achieve concatenation using compute fields ???
If you using a formula then use
Text(Numeric_field_Name__C) + text_Field__c
If you are trying it in apex code and want to store result in text field then use
string.valueOf(Numeric_field_Name__C) + text_Field__c
you can directly refer the y field since its numeric and then the rest as your are using it before. y + "Sometext"
