How to Know that Sales BOM is working or not?

I have set up a sales BOM. How do I know or test that is is working or not?

Once you enter a material (for whch you have created a BOM thru CS01) in the sales doc another material pops under the main material line item as a sub-item (s). If it doesn't then your BOM isn't working.

In my experience BOMs work if all maintenance has been done properly.

A number of things to check is:

1. The bom hasn't been defined for the plant used, or you haven't defined the plant in SO.

2. Main item category - has BOM application SD01 been assigned to it?

3. Item categories for main items and sub-items have not been mainteined properly.

4. Sales items maintenance - You should assign item categories for BOM header items and sub-items to a specific sales doc.

5. Has the BOM itself been configured properly (i.e. right plant, BOM usage '5')?

6. Are you trying it out on an order created after all BOM maintenance was done?

7. Also , what's the 'Structure scope' set as? Anything except C may be useful here? We have that set to A, since our BOMs are all single-level. You could set it to B if BOM are configured multi-level.

Those are probably main reasons why BOM shouldn't work. Apart from that, just re-check your whole config - the truth is out there somwhere
