When customer is updating ProjectContractLine by using Excel Addin, the contract value of the billing rule is going back to 0 when in fact only the Financial Dimension was amended.

Example: When Department X won't exist anymore, another department will be included and therefore, every Department in every billing rule should be changed accordingly, which is time consuming.
Example 2: Customer have ~3000 lines in one of their legal entity and more than ~5000 in another legal entity, so this means they manually need to change one by one every FD in the system.

It would be easier and not that time consuming for the clients if they use the entity in question.
