Tracking breaks in Reservation Table if Transfer Order Receipt Date gets updated.

Scenario 1

Distribution warehouse is supplied through transfer orders and sales orders are created based on receipt dates from transfer orders. In case of delay where transfer order receipt date is moved past sales order shipping date, tracking in reservation table is broken and line that shows which warehouse the transfer order is delivering gets deleted. Even if we move sales order shipping date to after transfer order receipt date, tracking is gone and the missing line is never shown again.

Scenario 2

Same as above but we are using "Tracking & Action Message" instead of "Tracking Only" and planning worksheets to calculate requirement. After repeating the scenario above and use "Get Action Messages..." on planning worksheets, the system suggests additional order for the sales order quantity even tough transfer order covers the required quantity.

Conclusion: The tracking is broken and if planning worksheets are used in scenario where transfer orders are used, the system can generate significant additional cost for companies that are using this functionality.
