BOM business requirement for sales order and PGI

Question

Hi Experts,
Current setting
The BOM structure is A = A1+A2
1) Material A created in MM master item category group = ERLA
2) Sub component material A1 and material A2, MM master item category group = NORM for both component.
3) Maintained in CS01 BOM header is A and items are A1 and A2.
4) Item category in IMG was created and assign item category also created.
    4.1) OR-ERLA-TAQ-TAE
new business requirement as listed below.
5) The material A is alway zero quantity on hand, no goods receipt required with no physical with such material or package at all. (it is dummy material number in SAP).
6) while SO created.
    6.1) Fro material A sales price captured at BOM header level only, NO QTY and COSTshow in the sales order.
     6.2) Material A1 and A2 are actual physical inventory item in the ware house.
     6.3) The sub component of material A1 and A2 is required to captured QTY and COST. NO SALES PRICES NEEDED.
CONCLUSION
HOW to setup/configure such a business scenario?
- Is it logic to configure as OR-ERLA-TAE-TAN that's what i think of?
  My problem is how to make the material A is alway ZEROS stock on hand and allow in sales order creation with ZEROS order qty?
MATERIAL                                          QTY                             COST                                  SALES NET VALUE
       A                                                      0                                   0                                              1,500.00
       A1                                                    1                                  100.00                                           0
       A2                                                    1                                    50.00                                           0

Answer 1

As per your post,
-  You are creating Main item which is a dummy material without any physical inventory maintained, but the pricing/billing should be done @ main item level.
- here you are not dispatching main item, but billing should be carried at this level. in such case, I suggest you to go with the new sch.line cat w/o maintaining any mov type to it. & use Zitem category for this main item in VOV7, mark "Order qtty=1" so that min order qtty for this main item should be 1, so that you can calculate price.
-  You want to capture Cost of sub items , summation of sub items cost is total cost of main item & Profit will be calculated accordingly.
Sub items, sch.line category should have mov type, item cat should be not relevant for pricing & billing , but relevant for sch.lines. In Copy control from delivery - Billing @ item level, for the main item ,- item category, choose "Cumulate cost", so that cost of the sub items will be cumulated to main item.
eg:
MATERIAL QTY COST SALES NET VALUE
A 0 0 1,500.00
A1 1 100.00 0
A2 1 50.00 0
My problem is how to make the material A is alway ZEROS stock on hand and allow in sales order creation with ZEROS order qty?
To avoid this, mark order qtty=1, in item category for main item, but for the same item, sch.line category should not have mov type. so that there will nt be any PGI document. But PGI should be done for sub items to capture inventory & cost.
Test & revert, if any issues.
