Hi ,
Looks like problem is due to
- Need to do ATP at componnent level which is only possible with Planning strategy 81,82. You cannot use planning strategy 40( 40 considers forecast , sales order & consumption)
- 81 ,82 planning strategy doesn't consume forecast for End item(Sales order entry material)
You could use Sales order BOM function. It is provided for selling Kits. BOM is exploded in sales order & kit items are put as seperate sales order items ( 20... 30... 40 ) Here are steps.
- Create BOM with usage 5- Sales order relevancy of bom components is Ticked
- Create Sales order with item which is BOM header. System will explode BOM & all items will be part of sales order as item.
- You can configure Sale Price at End FG level, Inventory management( DO issue) at item /components level .
- Forecast will be consumed at end item level.Need configuration
- ATP check can be performed at componenet level
Only thing is you will not have Plan order for doing assembly & there is no cost captured for assembly . Kitting donot involve much labor time.
Hope it helps
