• The major functions of this is for Customized Articles are BOM is explosion using CLSC SEARCH OBJECTS, BAPI CLASS SELECT OBJECTS so that correct articles
• Required in the user customized Product are selected, for each of the Components ATP is done and correct date is determined. After this the Time required for different MileStones in
• Customizing is determined and a final ship and delivery Date (based on the shipping method) is
• Computed. An Article can be in stock(MCHB,MARD tables),on order(PO tables), Drop Ship or
• Out of Stock. There are other Custom rules for protected customers, Customer eligible for
• Drop Ship qty, Euro Ship determination based on customer address being non US or PO Box Address.

• Be propagated back to CRM and Web and hence lead to inconsistent data To overcome this a
• Custom Batch split Functionality was developed. When a Batch Split occurs a entry in ZVVBE
