Hello everyone.
We have a problem in calculating of delivery lead times between tow warehouses in master planning.
Situation:
Item: Z0001, default order type = Production, Inventory lead time = 1 day, Item coverage settings: transfer from production warehouse 13 to sales warehouse 11, Transfer lead time = 3 days. Item Z0001 has no route, only BOM, so MP considers lead time.
Sales order: from sales warehouse 11, sales Qty = 1, delivery date = 2017-11-30
Problem:
After master scheduling:
In case when item Z0001 is on hand in production warehouse 13, master planning creates transfer order to sales warehouse 11 with transfer order start date 2017-11-27 and transfer order end date 2017-11-30 (the date of sales order delivery), that is correct.
In case, when there is no on hand in production warehouse 13, master planning creates tow planned orders, transfer and production, but planed orders start and end dates are wrong: MP creates planned production order with start 2017-11-29 and end 2017-11-30, and then planned transfer order with start in 2017-11-30 and end 2017-12-05, that is definitely wrong. In my opinion, planned transfer order dates must be as in first case (with on hand), transfer order start date 2017-11-27 and transfer order end date 2017-11-30 and then planned production order with start 2017-11-27 and end of 2017-11-26.
Please explain to me why a’m getting such a wrong dates?
