This optional feature defines how to translate a monthly demand plan forecast into weekly buckets. This is helpful when monthly demand should be translate weekly in either a front or back loaded manner in a month.

This process is an alternate to the weighted distribution calculation process that is covered in the Demand and Supply Translation article.

Currently, this process is only supported via a destructive upload file. This means that the new upload forces a delete on previously uploaded information so make sure when a new file is uploaded it retains the values that were previously uploaded or else they will be removed.

## Underlying Logic

The tab delimited file that is uploaded is named PercentageSplit.txt. As stated above, the file is set up as destructive. Meaning that the new upload forces a delete on previously uploaded information.

There are no specific settings to be readjusted. The logic is written in such a way, that it first checks if there is a Customer Code and Item Code pair in the Database Table associated with the Percentage Split Upload. If there is, then the Percentage Split logic and Weekly Percent Values are used. If not, then the default Month to Week distribution engine is applied.

If there is a Quarter Percentage Split uploaded for a specific Customer Code and Item Code pair, then the specific quarterly division depends on the length of the month (number of days in a month) with the following logic daily logic.

- In a 31 day calendar month the following month to week split is applied:
- Week 1 will have 9 days
- Week 2 will have 7 days
- Week 3 will have 7 days
- Week 4 will have 8 days

- In a 30 day calendar month the following month to week split is applied:
- Week 1 will have 8 days
- Week 2 will have 7 days
- Week 3 will have 7 days
- Week 4 will have 8 days

- In a 29 day calendar month the following month to week split is applied:
- Week 1 will have 8 days
- Week 2 will have 7 days
- Week 3 will have 7 days
- Week 4 will have 7 days

- In a 28 day calendar month the following month to week split is applied:
- Week 1 will have 7 days
- Week 2 will have 7 days
- Week 3 will have 7 days
- Week 4 will have 7 days

## Upload Format

There are 6 required columns in the PercentageSplit file. All months will follow the same split until a new file is uploaded.

- The first column defines the Item Code.
- The second column defines the Customer Code.
- The remaining four columns define the percentage weight value for each quarter. The columns are in order, starting with
- Week 1 and ending with week 4.
- The sum of the 4 weeks must always be 100, otherwise an error is thrown.
