How to change billable flag for expenditure items in expenditure inquiry form?

 Hi Everyone,

Here is the situation we have:

1) All expenditure items for a project are non-billable except 2, and we need to change them from billable back to non-billable.

2) Revenues have been generated for the two items

3) When I tried to make the change from tools/non billable 1 in expenditure inquiry form, I got this message: The transaction source for this expenditure item does not allow this action.

4) There is no difference between the billable items and non-billable items in pa_expenditure_items_all table.

Any comments/suggestions will be highly appreciated.

Thanks,

Ning
