CPQ and CPS limitation

• CPS accepts numbers only in a standard format using '.' as the decimal separator. Language dependent formats (using ',' as decimal separator) are not supported
• For Standard Attributes, when CPQ performs CPS calls, there is an implicit number format conversion, to dot decimal separator, in order to allow number to be passed to CPS
• For Dynamic Attributes the same conversion is not done, thus error is thrown
• Workaround is to avoid using Number Formats that contains comma as decimal separator when having Dynamic Attributes, or change number format using script
• Currently there is no plan to add the implicit conversion in the CPS call for Dynamic Attributes
• It is recommended to create/upvote enhancement request for feature.
