Sales Plans in Standard SOP: Copying Data from SIS 

The planning functionality of Sales & Operations Planning is part of the Logistics Information System (LIS). Thus, you have direct access to the quantities planned in the Sales Information System (SIS) from SOP. All you need to do is specify the information structure, the planning version, and the key figure whose data you want to copy. If you want to use these settings on a regular basis, you can predefine them in your user-defined values. The only requirement is that your chosen information structure contains material as one of its characteristics.

What you are in fact doing is copying data from one information structure to another (see also Copying Data from One Information Structure to Another): product group plans are based on information structure S076.

You can copy the values of any quantity key figures in your specified information structure. For example, you can copy planned order quantities, planned invoiced quantities, or planned delivery quantities.

In order to create a sales plan for a product group, the system aggregates the planning data of all the materials in the product group hierarchy with reference to the plant and period indicator. If plant is not contained in the information structure key, the system distributes the quantities across a material’s plants in accordance with the settings made in the Customizing activity "Define proportional distribution across plants".
