Hi Gurus,

My requirement is to create a higher level BOM which would constitute other BOMs. When entered in the sales order, we want the BOMs to explode at all levels. I tried to do this by setting the BOM structure scope B in item category of sub-items but does not work.

I get this below message.

Structure explosion for item 000011 is not possible

Message no. V1578


You have tried to carry out a structure explosion within an exploded structure, but this is not possible.

For example, the system finds one component and one item category within an exploded BOM that leads to another BOM explosion in document processing. This is not possible because you can only explode a multi- level BOM and the explosion can only start with a document item that has not been generated by the previous explosion.

Similar problems occur when combining BoM explosion and product selection.

System Response

The system does not carry out the lower-level explosion.


Configure the settings in Customizing, so that sub-items do not lead to another explosion. It might be that the wrong item category was determined for the sub-item.

Please help me with the required configuration steps.
