Difference between material and equipment bom

Can someone please specify the difference between material and equipment bom with examples.

Where do we use equipment boms and whethere there are any reports?

And also the link between material bom and assembly?

Let's take an example for this;

Say you have a Pump (Equipment) and its bill of material include following things;

1. Rotating Assembly

2. Pump Housing

3. Mechanical Seal....etc

Now many companies keep complete rotating assemblies which includes the following readily available to handle breakdowns;

1. Shaft

2. Shaft Sleeve

3. Bearings

4. Impeller

5. Coupling

6. Keys (installed on keyways)

So we create Rotating Assembly as a material, pump housing and mechanical seal as separate materials. Now parts under Rotating Assembly are also made as materials.

We create Material BOM, which is made for rotating assembly and which will in turn have the above mentioned materials with required quantities.

Now we create Equipment BOM, which is made for the pump and which in turn with have the 3 materials. So when you see the structure under say IH01, you get functional location, pump followed by pump's BOM and then the assembly's BOM.

The material BOM also allows users to procure directly from the manufacturer i.e. the rotating assembly in this case.

I hope this is clear.
