| # Transportation time for linked assembly lines A supply line linked to multiple parent lines, can be physically present in the same geographical location as the parent lines or can be located in a different geographical area. If the supply line is located in a different geographical area, the time to transport assembled components to the parent line must be taken into account when planning the assembly orders. Note The transportation time for the supply of assembled components between the supply line and parent lines must be defined for multisite assembly scenario as well as the single site assembly scenario. The assembly lines must be logically linked in the assembly line network structure. Example The following example shows a supply line which is linked to two different parent assembly lines. Supply Line z linked to main lines A and B
A | First main parent line
B | Second main parent line
Z | Supply line for main lines A and B
S1A to S3A | Consecutive line segments on main line A
L1A to L3A | Consecutive line stations on main line A
S1Z to S2Z | Consecutive line segments on supply line Z
L1Z to L2Z | Consecutive line stations on supply line Z
S1B to S3B | Consecutive line segments on main line B
L1B to L3B | Consecutive line stations on main line B

- The tranportation time is calculated based on the following: Address of the line station on the supply line. Address of the line station on the parent line. To calculate the transportation time, you must link the last line station of the last line segment of the supply line to a line station on a parent assembly line. In the above example, the last line station L2Z of the last line segment S2Z can be linked to L3A on main line A and/or to L3B on main line B. You must define the address for the linked line stations and use the distance tables in Freight to calculate the transportation time. Note If multiple supply lines are linked to the same line station on the parent assembly line, each supply line-parent line combination can have their specific transportation time. Important! The transportation time is displayed only on the line station order related to the last line station of the last line segment on a supply line. The transportation time is taken into account for the following processes: Generating Assembly Orders: When assembly orders are generated, line station orders (LSO) are also generated. The Planned Transport End Date of the line station order related to the last line station of the supplying line, is set to the start date of the assembly order. The Transport Time is set to zero. Offsetting line station orders where the Assembly Order Status is Planned: Offsetting line station orders is based on the transportation time and the defined line segment lead time offset . The Planned Transport End Date of the line station order related to the last line station of the supplying line is set to the end date of the line station order. The value of the Transport Time field is set to zero. Offsetting line station orders where the Assembly Order Status is Sequenced: Offsetting the line station orders on the supplying line is based on the transportation time in order to determine the start time and end date of the line station orders on the supply line. The Planned Transport End Date of the last line station order on the last line segment of the supply line is set to the Planned Start Time of the linked line station order on the parent line. The Transport Time is calculated using the following formula:
      Planned End Time - Planned Transport End Date
While calculating the transport time, the values from the last line station of the last line segment of the supply line are considered. Line sequencing: The transportation time is taken into account during the Synchronizing Supplying Lines process for assembly orders with the Sequenced status. The start time of the (LSO) of the line station on the parent line is offset with the transportation time to determine the end date of the LSO of the last line segment of the supplying line. In case of a multi-site assembly model, this end date on the last line station order is equal to the offline date of the assembly order, on the supplying line. Determining segment schedules: The transportation time is taken into account when segment schedules are calculated. The transportation time is used to offset line segments when the dates at which the assembly parts are required, are calculated.
