Currently WIP is run for all Methods and user is required to put in cut off date. In order to get WIP for the future scheduled billings WIP needs run for a future date. However if there is a mixed method of calculation on the project (some TM and some fixed) then it is not possible to run WIP for current date for TM and future date for FP. It would be easier if there was a field with Contract Value that is allowed to be defined at the contract level and the task level. then run WIP using that value rather than the scheduled billing lines
