What the inventory receipt transaction that no affect project actual cost

Summary:

Hi

We are implement project number in one of chart of account segment. We have test some scenario between project and inventory:

1. We create PR-PO-Good Receipt for specific project, with cost in item cost is 1000. When we run import cost, the project actual cost is 1000. We dont send the project number to the chart of account segment.
2. We want to issue this item or material, but without affecting the project actual cost. So, we create movement request issue. The project actual cost still 1000. We send the project number to the chart of account segment.
3. In the real life, we only use the material only 80%. So, we create miscellaneous receipt for the rest of unused material with the cost 200 (1000-800). But the project actual cost increased from 1000 to 1200 (1000+200). Logically we only return the rest of unused material refer to this project and we send the project number to the chart of account segment.
