The Propel team are currently in the process of rolling out a change that will allow you to map cost centres by a line of business value. Currently your cost centres are mapped by your country code and the changes that will be applied will append a line of business value to the country code.
This means that we will need to change your cost centre mapping data to add a line of business value to your country code. This will allow you to map separate PO lines to a different cost centre based on the line of business value. We can also map each line of business to the same cost centre (as at present) if you so require. We will also need to leave the current mapping without a line of business value as some orders are interfaced without a line of business value.
