Hi
In our company - we are going to use CTP but we discovered a strange behavior of CTP in the following case:
1. An item 'Product_A' is created having ONLY one line in BOM -> an item - 'Material_B' (no route is defined for Product_A) - 1 pcs of Material_B for 1 pcs of Product_A;
2. Material_B is purchased and has lead time = 14 calendar days;
3. Currently there are 2 pcs of Material_B on stock available;
4. Sales Order line for 2 pcs of Product_A is created with confirmed shipment date 4 weeks ahead (longer that delivery lead time of Material_B) with CTP defined as method of checking delivery date;
5. So far - so good - CTP allows define shipment date 4 weeks ahead as acceptable;
6. Next sales order line for Product_A is created for 1 pcs and expected confirmed shipment date is 10 days ahead (within delivery lead time for Material_B);
7. ATTENTION !! CTP suggests earliest available shipment date as 14 days ahead (lead time for Material_B) instead accept shipment 10 days ahead. Why I expect that? There is stock level available of Material_B (2 pcs) already on stock for delivering 1 pcs of Product_A within 10 days - and - there is enough time to buy next pcs of Material_B for delivery of 2 pcs of Product_A within 4 weeks (period longer that LT for Material_B) !
But CTP doesn't allow shipment date 10 days ahead !
Do you know if MS solved that bug ? Or there is another solution for proper calculation of CTP in the situation as described above ?
I would be glad for any advice/help
