Split shares control how the system splits weekly or monthly schedule lines in a forecast delivery schedule into daily schedule lines in the planning delivery schedule. Using split shares, you can define a finely tuned split or a more general split according to your planning requirements.

The system determines days and split shares in the new planning delivery schedule for the corresponding weekly or monthly schedule line in the forecast delivery schedule. It calculates the average quantity (the schedule line quantity divided by the sum of split shares) and assigns this quantity to days according to the number of split shares per day.

You want to split the schedule line in the forecast delivery schedule for week 25, 1998 (06/15–06/21) with 600 pieces. In Customizing, you maintain the splitting rule, assigning one split share each to Monday, Wednesday, and Friday. When you generate the new planning delivery schedule, the system calculates the average quantity by taking the schedule line quantity and dividing it by the split share sum. The system then assigns this quantity, 200 pieces (600 pieces divided into 3 split shares), to each split share. The resulting planning delivery schedule has 3 daily schedule lines with 200 pieces each.

Using the same splitting rule, you want to split the schedule line in the forecast delivery schedule for month 07, 1998 with 1,820 pieces. In this example, there is a total of 14 split shares – 14 days (Mondays, Wednesdays, and Fridays) in July that have been assigned one split share each. When you generate the new planning delivery schedule, the system calculates the average quantity, 130 pieces (1,820 pieces divided into 14 split shares), and assigns it to each split share. The resulting planning delivery schedule has 14 daily schedule lines with 130 pieces each.

When you work with a total of 100 split shares for a weekly schedule line, the split shares you assign to weekdays are, in effect, percentage points.

You want to split the schedule line in the forecast delivery schedule for week 25, 1998 (06/15–06/21) with 600 pieces. In Customizing, you maintain the splitting rule, assigning 15 split shares each to Monday and Wednesday; 30 split shares each to Tuesday and Thursday; and 10 split shares to Friday, for a total of 100 split shares.

When you generate the new planning delivery schedule, the system calculates the average quantity, 6 pieces (600 pieces divided into 100 split shares), and assigns it to each split share. The resulting planning delivery schedule has the following daily schedule lines:

• Monday and Wednesday are assigned 90 pieces each (6 pieces x 15 split shares, or 15% of the total schedule line quantity)
• Tuesday and Thursday are assigned 180 pieces each (6 pieces x 30 split shares, or 30% of the total schedule line quantity)
• Friday is assigned 60 pieces (6 pieces x 10 split shares or 10% of the total schedule quantity)

Using the same splitting rule, you want to split the schedule line in the forecast delivery schedule for month 07, 1998 with 1,820 pieces.

When you generate the new planning delivery schedule, the system calculates the average quantity, 4 pieces (1,820 pieces divided into 455 split shares for the whole month), and assigns it to each split share. The resulting planning delivery schedule has the following daily schedule lines:

• Mondays and Wednesdays are assigned 60 pieces each (4 pieces x 15 split shares)
• Tuesdays and Thursdays are assigned 120 pieces each (4 pieces x 30 split shares)
• Fridays are assigned 40 pieces each (4 pieces x 10 split shares)

By assigning split shares to only one day for each week for a month, you are in effect, splitting monthly schedule lines into weekly schedule lines.

You want to split the schedule line in the forecast delivery schedule for month 07, 1998 with 1,820 pieces. In Customizing, you maintain the splitting rule, assigning only one split share to Monday. When you generate the new planning delivery schedule, the system calculates the average quantity, 455 pieces (1,820 pieces divided into 4 split shares for the whole month), and assigns it to each split share. The resulting planning delivery schedule has 4 daily schedule lines (all Mondays) with 455 pieces each.
