Maintain Planning Restriction for Routes

There are cases in which the whole shipment run is not determined by a transportation planning system for individual deliveries. If a company sends deliveries both inland and overseas it is feasible that you will need to use a planning system in order to optimize planning for the inland shipment on roads, but that shipment documents need to be generated manually using R/3 transactions for the overseas transportation (sea routes). In this case, the transportation planning system has to be notified that the destination location abroad is not the definitive one. Instead this will be another location, to which automatic planning will be carried out (for example, the departure harbor or a border location). Similar situations can arise for purchase orders sent from shipping points outside the planning area of a transportation planning system.

In planning restrictions, you can determine which substitution procedure should be used to find a substitution location for the shipping and / or destination location of the delivery separately for each combination of transportation planning system and route.

A substitution procedure is composed of a sequence of conditions, which are checked one after the other until a valid substitution for the departure or destination has been found. Once the system has found a substitute, it changes the times specified for the location.

For example: Substitute Location for Subsequent Leg Planning

The "German Roads" planning system is used for the "North America to Hamburg" route for planning subsequent legs. Therefore, the delivery's departure point in North America, that is, outside the planning area, needs to be substituted with a suitable starting point. The following are suitable condition sequences that the determination procedure should process in sequence until it has found a substitution:

In this activity, you can maintain planning restrictions using the following steps:

• Maintain individual entries and substitution procedures in the table

• Insert route areas to the table (mass transaction)

• Copy route areas in the table under "Changing Transportation Planning Point (mass transaction)

Activities

• Maintain individual entries directly in the table:
  Enter the transportation planning point and the route you want to restrict in the table. Maintain the required substitution procedures and transportation connection points for the start and end of planning. Enter the required travel times for the preliminary, main and subsequent legs. The total travel time must be equal to or less than the total transit time of the route.
  You must always enter the travel times in days with two decimal places. This means that you can only specify them down to 15 minutes. The maximum value is 99 days. Use the possible entries help to enter time values in days, hours and minutes. Because of the limited number of decimal places, you will have to allow for inprecise minute calculations.
  

• Maintain the substitution procedure
  Choose a substitution procedure that you want to maintain or create a new one. Maintain the condition sequence for the procedure so that it meets your requirements. You can use the existing conditions and you can also create your own. You can also use your own determination routines to substitute the location (see below).
  

• Enter route areas in the table (mass transaction):
  It is useful to enter route areas if you want to restrict the planning for a large number of routes that are set up according to a certain procedure.

• On the selection screen, enter a transportation planning point and a route for which you want to add entries. For the departure and destination point for each new entry, specify which substitution procedure and which defined transportation connection point should be used. You can also specify the travel times for preliminary, main and subsequent legs but only if their total exceeds the total transit time. You can also choose whether to keep or overwrite existing entries for the transportation planning point / route.
  

• Copy route areas with changes to transportation planning point (mass transaction):
  You should copy the route areas if you have several planning systems with the same planning area, for example, and you just want to copy the planning restrictions.
  Enter a transportation planning point and a route on the selection screen whose entries you want to copy. You must also specify for which transportation planning point you want to copy the entries. You can choose whether to keep or overwrite existing entries for the new transportation planning point / route.
