PP: MRP and Production order scheduling

SAP scheduling in MRP and Production orders explained below:


For MRP (Planned orders):
Available for Planning Date = Requirement Date
Order Finish Date = Avail. for Planning Date minus GR processing time
Order start date = Order finish date minus In house production time from Mat Master
Opening date = Order start date minus Opening Period from schedule margin key


When manually creating planned order, user enter the order finish date. Available for planning date is then obtained by adding the GR processing time to it.


For Production orders:
Scheduled finish Date = requirement date minus GR processing time minus float after prd.
scheduled start date = scheduled finish minus sum total of operation execution times - float before prod.
release date = scheduled start minus release period from schedule margin key.

CO: Order Confirmations link to controlling

Task: Link between a confirmation posting done in a PP or CS order with controlling.

Tables: AFRU and COBK

Explanation: Confirmation number (RUECK) is a unique number identifying "a" confirmation transaction, and this can be a bit confusing. A confirmation number is assigned at the time of order creation, to each operation of an order that is confirmable (well, if you are using operation-wise confirmation, I guess!) and therefore exists even before any single confirmation is posted for the order.

To identify a single confirmation transaction that happened for an operation, it is necessary to know both the confirmation number (RUECK) and the confirmation counter (RMZHL).

When it comes to the CO documents for confirmation, these are held in tables COBK and COEP.

The links between the confirmation postings in logistics (CS/PP) and controlling are:


COBK-REFBN = AFRU-RUECK
COBK-AWORG = AFRU-RMZHL
