Original request from hiep:

Implementation:

1. Copy existing data from M_Product_BOM to PP_Product_BOM and PP_Product_BOMLine

2. Rename table M_Product_BOM to M_Product_BOM_Old

3. Re-create M_Product_BOM as view that build on top of PP_Product_BOM and PP_Product_BOMLine

4. Change mfg-light to use PP_Product_BOM and PP_Product_BOMLine

   1. add PP_Product_BOM_ID to M_Production

   2. add PP_Product_BOM_ID parameter to Production Create process

5. With the potential of multiple BOM for a product, BOM with BOM Use=Master and BOM Type = “Current” is use as the default BOM of a product (and for M_Product_BOM view).
