Redistributing Allocated Quantities Within an
Allocation Group 
Use
The purpose of this function is to improve the quality of the allocations (assignments or ARun results).
ARun allocates stock using a predefined strategy and parameter set (such as release rules). If there is not enough inventory to meet all the requirements, these predefined configuration controls determine how the system handles the material shortage.
In the ARun Optimizer, customer service representatives (CSRs) can see the results of previous allocation runs. If they do not like how the system allocated stock using the default strategy, they can select a different ARun type or configuration in the ARun Optimizer to reallocate the existing assignments and to maximize shipments. For example, if an allocation run distributed stock evenly across the allocation group, the CSR can redistribute it using a different strategy (such as FIFO).
Customer service representatives are likely to use this function on a daily basis.
Prerequisites
To define the default allocation strategy:
...
1. In Customizing, choose AFS Allocation Run ® ARun Optimizer ® ARun Optimizer Control ® Configure ARun Optimizer Type.
2. Choose the ARun Optimizer type you want to change and select Details.
3. In the Proposals section, select the allocation type with the allocation configuration you would like to use to obtain desired allocation results.
Activities
To redistribute allocations for a given allocation group:
...
1. In the ARun Optimizer, display the results of the previous allocation run.
2. Select the line with the allocation group to which you want to make changes. (Alternatively, you can drill down into the allocation group, then choose one or more individual orders and only deallocate them).
3. Choose Allocation ® Allocate.
The system displays the allocation dialog box.
4. Choose one of the following options:
○ Accept the default ARun type
You can optionally change the configuration for that ARun type by choosing Expand. This allows you, for example, to change the allocation logic from FIFO to SPREAD, activate a release check other than the default, or activate/deactivate a category check. These changes are temporary; that is, they are valid only for this ARun reallocation process and do not change the ARun type. Subsequent allocation runs using that ARun type will revert back to the default values.
○ Choose a different ARun type instead of the default.
Here, too, you can temporarily change the configuration as described above.
This transaction does not support redistribution of unrestricted stock. You must first move unrestricted stock into your shared buffer, and then proceed with the redistribution.
Example
Assume that an allocation group has 5 orders, each specifying 10 pieces of the same SKU. There are only 33 pieces in inventory. If you use an even spread strategy, the system allocates the stock as follows:
Order |
Material |
Size |
Requirement |
Allocated |
1 |
12345 |
Large |
10 |
7 |
2 |
12345 |

If you redistribute using a FIFO strategy, the system reallocates the stock as follows
Order |
Material |

In total reallocation, selected allocations are first deallocated and then fresh allocations take place. But, redistributing allocated quantities within an allocation group does only allocation.
