Check Settings
for Formulas
Formula parameters are used in formulas for
capacity planning, scheduling, costing, PRT management and determining
standard values using CAPP.
A formula parameter is identifeied by a
parameter ID. Every formula parameter is linked with
a particualr field either in Customizing, the routing or the work center. When
the formula is evaluated the parameter takes the value of the
field.
Origin of Formula
Parameters
The assignment of a formula parameter to a data
field is defined in the origin . You can refer to
the data field in the work center or the routing via the
parameter-ID or the key word that is
assigned to every formula parameter and is displayed next to the the data
field in the routing or work center. Formula parameters can have the following
origins:
Using the
standard value key you provide the work center, and thus the
routing, with up to six formula parameters that you assign values to in the
routing operation.
In the work center
you can assign up to six work center constants a value and an
unit.
- General Formula
Constants
You can assign
general formuula constants a value and an unit in Customizing formula
parameters.
The formula
parameter is assigned to a data field in the general operation data, for
instance the lot size or the base quantity. In this case you have to
explicitly enter the field name .
- User-Defined Field from
Operation
The formula
parameter is assigned to an user-defined field in the operation. In this case
the the assignment of the formula parameter is controlled by
user-defined field key, that you define in Customizing the work
center. The key words that describe the data fields are not defined in the
formula parameters, but in the user-defined field key.
- Value from PRT
Allocation
You assign the
formula parameter to a field in the PRT alloaction, for instance the PRT
quantity.
You assign the
formula parameter a fixed value in the PRT master record.This formula
parameter can only be used for PRT management.
Note:
You enter the meaning of the fields in the key
words for work centers and routings and not in the field
names.
Please note that this step is the prerequisite
for the step
Define rounding categories and additional values key in
Customizing for CAPP standard value calculation.
If you want to use the parameters in formulas
you should use descriptive parameter IDs.
- The value that you enter in the
std. value field is only used to check the syntax of the formula
(apart from general formula constants). The system does this automatically
when you create a formula in Customizing. You should maintain this field,
specially if a formula parameter is used as a divisor in a formula. Similiarly
the Standard value unit field is only used for
checking purposes.
Actions
1. Define your
formula parameters.
2. Check the
assignment of the formula parameters to the standard value keys.
3. Check the
use of the formula parameters in formula definitions.
