Changing a BOM Group (Variant Document Structure) 
Prerequisites
You are processing a document info record that has a document structure or BOM group.
Procedure
You see the Change BOM Group: Initial Screen.
To do this, enter either the BOM group or the fields of the document key.
If you enter a change number, the change master must allow the processing of document structures.
If the change number identifies an engineering change request, your document structure must be defined as a change object, and the change request must have been approved and converted to an engineering change order.
This overview shows a list of all the items of the BOM group, including the component quantities. The list of alternatives contains all the variants in the BOM group. In each item block, the system marks the variants in which the item concerned is used.
– Displaying all the item data
Select the item(s) and choose Complete item data. You see the General item data. From here, you can call the other detail screens.
– Displaying variants
To do this, call up the Summarized BOM screen and choose Var.Overvw.
– Changing the component quantity
To do this, call up the Summarized BOM screen. Please note that this change affects all the variants where the item is used.
If you want to enter a different component quantity for a specific variant, you must recreate the component with the new quantity and allocate it to the variant concerned.

On the Summarized BOM screen, the allocation of the item to a variant is only displayed. If you also want to use the item in another variant or delete it from one or several variants, change the allocation of the item to the variant concerned on the Item in Variant(s) screen.
Select the item on the Summarized BOM screen and choose Item variants.
You see the Item in Variant(s) screen, containing a list of all the variants in the BOM group. You can set the allocation indicators here. The system copies the allocation to the Summarized BOM screen.
To do this, call up the Summarized BOM screen and choose New items.
You see the New Document Items screen, on which you enter the fields of the document key as well as the quantity. When you create the item, you immediately assign it to a variant on the Summarized BOM screen.
Select the item on the Summarized BOM screen and choose Delete item.
