In eBiss 3 the mapping functions Get… Variable (e. g. GetTradingPartnerLocationVariable) return a logical value, true or false if the variable is a boolean variable. In eBiss 2 the string' True' or' False' was returned.

Each string that is not empty is true, i. e.:

• boolean('True') = true
• boolean('true') = true
• boolean('False') = true
• boolean('') = false

To avoid errors in eBiss 2 and to keep the mapping compatible with eBiss 2, compare the result of these mapping functions (Get… variable) with the logical expressions true () or false () instead of the character strings' True' or' False'.

• true() is converted into a character string, for example, when comparing it with a character string, results in' True' and
• false() becomes 'False'.
