 Determining a Default for Yield Locate this document in the navigation structure

In Customizing, you can specify that the system suggests a yield to be confirmed for each confirmation. Either the order quantity or the quantity of previously confirmed operations is taken into account. The following settings are relevant:

  • In the confirmation parameters (Customizing for Shop Floor Control, choose   Operations   Confirmation   Define Confirmation Parameters)   you set the Propose indicator in the quantities area, to stipulate that quantities should be proposed when confirmations are entered. The same key is found in Customizing for Single Screen Entry (Customizing for Shop Floor Control , by choosing   Operations   Confirmation   Single Screen Entry   Define Single Screen Entry   ).

  • In the confirmation parameters, you also specify what should happen if you do not adhere to the sequence of operations when entering confirmations ( Operation sequence key) Possible message types are: No message, information, warning, error.

  • When you define a Control key for operations (in Customizing for Shop Floor Control by choosing   Master Data   Routing Data   Define Control Key)   , you stipulate whether an operation can or must be confirmed ( Confirmations key).

Note Note

For confirmations of individual capacities (capacity splits) the planned quantity of the relevant split is used instead of the underdelivery tolerance.

End of the note.

How the default quantity is determined, is described below. It makes no difference if the sequence of operations is to be kept to or not.

Operation Sequence is not Relevant

The system suggests the yield from the last finally confirmed predecessors (except rework operations). If there are no finally confirmed operations, the system uses the order quantity.

Operation Sequence Should be Adhered To

The following graphic illustrates which factors have an effect on the default quantity if the operation sequence is to be adhered to.

Parallel Sequences

If an operation has several predecessors (parallel sequences), then the default quantity is the smallest quantity from the various operations.


If rework operations follow the operation in question, the confirmed quantity of the rework operation is added to the quantity to be confirmed.

Checking the Quantity to be Confirmed

If the operation sequence is checked for confirmations, then the following quantity check takes place: If you want to enter a confirmation in which the sum of the yield, rework quantity and scrap is larger than the yield of the predecessor, then the system issues an appropriate message (for example, an error message). The predecessor is determined exactly as described in the graphic.

Irrespective of whether the operation sequence is adhered to, the quantity is checked against the quantity of the predecessor operation (= expected quantity) and a message is issued (the category is set in Customizing). The following cases can occur:

  • The confirmed quantity is larger than the expected quantity.

  • You are entering a final confirmation and the confirmed quantity is smaller than the expected quantity.

The message category determines your next entry option:

  • After acknowledging a warning, you can continue entering.

  • In the case of an error message, the system terminates the input dialog.
