I re-entered a sales order and added a few items via my F&O setup, these were type B items.
 
The parts on these type B bom's never make it to the MRP.
 
The result was we didn't know we needed them and now things are running late because they were not ordered.
 
Should the items on the type B boms be eliminated from the MRP creation ?

There were type B items added to a sales order.
 
One bom had 1 type A Item on it the other was a type R item.
 
Both were flaged for mrp as was the top level item.
 
neither showed up on the mrp at all

1. How did you add the B type items?  
 
deleted and re-entered the sales order
 
2. Were the items added before the SO-N to WO conversion? F&O won't hit mrp (or the reorder report) until the SO is converted to a Work Order.
 
 
So F&O items are treated diffrently by the MRP when they are on a sales order.
 
I was depending on items on the sales order to show up on the MRP they were purchased items that would have been on the w/o bom but were added after the original w/o was created.  
 
However they were only on the sales order. and when you run mrp it lets you include sales order items
 
 
I guess I assumed that the MRP would drill down into the sales orders and make sure we were covered.
 
At least with a planed order.
 
 
3. Do they show up on the WO bom?  
 
They did not because this was after the WO creation material issue and labor had started.
 
Im think I should have issued a new sales order for the job changes  since it was just additions to the job.
 
We manually added them to the w/o bom and yes now they show on the MRP and all is well.
