BEFORE

BEFORE(data,substring);

Using this function, the data before the specified substring will be returned. The result is returned as a text.

Examples:

We have a field called "Company Name" with the value 'Rapidi A/S'

##BEFORE("Company Name", ' ')

The formula will return 'Rapidi'.

##BEFORE("Company Name", 'Rapidi')

The formula will return NULL because there is no value before 'Rapidi'.

##BEFORE("Company Name", 'A/S')

The formula will return 'Rapidi' with a blank at the end.

##DBLOOKUP('DESTDS','Account','Customer_No__c',BEFORE("DimensionDisplayValue",'-'),'Id'))

The nested formula will retrieve the value that is stored before the first minus sign - in the field 'DimensionDisplayValue'. If the vale retrieved equals Customer_No__c, then the ID will be retrieved.
