I post a question in google group.
Carlos advise me to make a improvement ticket.
Currently, Manufactoring light cann't setup mutil BOM for a product so howto I can handle for the following cases.
I have product "A" with two route process,
1. normal route process from the raw material to the finished product, the BOM of A is (a1, a2, a3, a4, a5).
2. other route process as below
a. producing the temporary product "B" with BOM is (a1, a2, b1, b2, b3)
b. the Product "A" to be producing from product "B" with BOM is (B, a3, a4, c1, c2)
Reopening this ticket for mfg-light
Reproduced by in 7.1
The table M_Product_BOM rename to M_Product_BOMLine
Create new table M_Product_BOM as header of BOM (see for example LiberoMFG)
In Production add field M_Product_BOM_ID IsMandatory = Yes
Then need change all functional for this new DB structure
