You use this procedure in master recipes to edit apportionment structures for the header materials of the master recipe.

• A production version for the material-recipe combination exists.
• The alternative BOM that is assigned to the recipe in this production version has been created in the system.
• If you have just edited the material list or bill of material of another production version in the master recipe, you must access the recipe group again. For technical reasons, you can only display or edit the material data for one production version in a transaction call.

1. Go to the material list of your master recipe (Materials tab page).
2. If more than one header material and/or production version exists for your recipe, select the material or production version whose data you want to edit.

The material list appears.

3. Choose .

The screen where you can edit apportionment structures appears.

4. Enter a key and a description for the apportionment structure.
5. If you want to edit cost apportionment for cost elements, you must also enter an origin structure to which the required cost elements are assigned.
6. Position the cursor on the apportionment structure and choose Equivalence numbers.

The screen for equivalence number editing appears.

7. Make an entry for each co-product or each co-product and cost element (Assignment), if you have edited an origin structure.
