Source Allocation in the Dialog – Without Rescheduling

Use

You can execute the source allocation as a dialog application or as a batch run. You define new sort and vendor ranking criteria in the dialog for every source allocation run.

Procedure

Choose Logistics ® Materials Management ® Source Allocation ® Standard Source Allocation. Enter the required data in the Report Selection screen and choose Execute. You can save your report selection as a variant.

In the subsequent selection screen, specify for which purchase requisitions you want to carry out a source allocation and flag the corresponding lines.

Note

To go to the item overview of a purchase requisition, double-click on the corresponding table entry.

To specify sort and vendor ranking criteria, choose the pushbutton Sort/vendor criteria in the AFS Selection screen for requisition. With the sort and vendor ranking criteria you define your company and personal preferences that result from your business strategies and business plans.

To start the simulation run for the selected purchase requisition, choose Start Simulation.
All purchase requisitions that have been assigned a vendor are displayed in a table.

Assigned vendors are displayed in the table column Fixed vendor.
You get an overview of all selected purchase requisitions that could not be assigned a vendor in the simulation run via No P.R. assigned.

Before triggering the update of the purchase requisition at database level (Generate P.R.) you can compare different simulation versions. Proceed as follows:

Choose Compare Simulations.
You then see a listing of all the purchase requisitions you have selected. The assigned vendor is displayed in table column Act.Vers. If the source allocation could not assign a vendor, you get information on the missing assignment by double-clicking on this field.
Additional information on the capacity situation or the quota utilization before and after the simulation can be displayed if desired. For this choose Simulation ® Capacity Simulation or Quota Simulation ® Display. The table columns Old and New enable you to directly compare the situation before and after the simulation.
You can save the current simulation run as a version (Save version). This allows you to specify other sort and vendor ranking criteria for a new simulation run and to compare this data with the data of the first simulation run. The data of the saved version in the table column Save Vers is compared to the current data (table column Act. Vers).
Via Generate P.R. you can trigger the update of the purchase requisition at database level. You can choose whether the update should be based on the current or the saved version.
