Cost Centre code should be generated based on link between Project class and cost centre

Summary:

We got a specific requirement If the requisitioner select project number (project details such as project number, task and exp type) in requisition line then cost centre code should be auto generated at 'Distribution charge account 'based on the link between expenditure org and cost centre or Project class and cost centre. Requisitioner wouldn't be able to amend the cost centre, if requisition line have project details

If the requisition line is non project one, then user can select any cost centre based on Req preference or user can key in.

At the moment user can select cost centre based on requisitioner discretion whether its a project or non project requisition line
