A Reservation document consists of a header and at least one item
The header contains general data about the reservation (creator, movement type, account assignment).
The Item describe individual planned movements (material, quantity, requirement date)
Note: You can create a reservation for exactly one purpose only. i.e. you can enter only one movement type and one account assignment object (like cost center)
Reservations are made at the plant or storage location level.
For materials handled in batches, reservations can also be made at the batch level.
Reservations can be created manually or automatically. SAP supports
There are two types of automatic reservations
Note: You cannot change the reservations that were created automatically. If you need to change the reservation you would have to change the original production order.
Note: You cannot maintain automatic reservations directly. For example, it is not possible to change reservations for orders directly. You have to change the components in the order. The system then updates the reservation automatically.
Displaying the reserved stock: There are two functions available for displaying reserved stock Stock overview at the plant level
When you use this function, the system displays the total reserve stock of the material at the plant level. From the stock overview, you can select environment -> to display a list of the reservations for the material
Current stock/requirement list: When you use this function, the system lists all the open reservations for the material at the plant level along with the reserved quantities for each.
You can change the field selection depending on the movement type.
You can define per plant whether the R/3 system is allowed to create a stock segment for reservations in a particular storage location automatically.
