Characteristics and tables serve as the basis for calculating standard values with CAPP. They are used in CAPP elements.

Characteristics

A characteristic describes any detail or feature of an object, such as the length of a screw or the color of a casing. Characteristics are used in formulas for calculating standard values. They are also used in classification.

You can maintain the characteristics for formulas either directly in characteristic maintenance or when creating a formula by branching to characteristic maintenance.

To reduce the amount of data you need to enter to calculate standard values, you can specify one or more default values for characteristics in characteristic maintenance.

For additional information about characteristics, refer to the CA - Characteristics guide.

Tables

You can also save data in tables. You can use this information for calculating standard values. Tables consist of key fields (for example, plant and work center) and one or more values in the function section of the table, which refer to the key fields.

Tables are created using the ABAP/4 Dictionary. You can define the table structure using data elements and domains. For example, you can determine how many values can be entered in the function section of a table. You can find information on creating tables in the guide BC - ABAP/4 Dictionary .

You can use the following table types for standard values calculations:

  • General tables : In a general table, function fields are assigned to any table key. You can use search rules to define how a value is to be taken from the table.

  • Tables for work centers : In tables for work centers, function fields are assigned to a table key consisting of work center and plant. You can use search rules to define how a value is to be taken from the table.

  • Matrix tables : In matrix tables, a series of individual values is assigned to a table key. These values must be sorted in ascending order. Matrix tables are suitable for specifying feed sequences or speed sequences. You can use conversion rules to specify how a value is to be selected from the sequence for the standard values calculation.

Note Note

All the fields in the function section of a matrix table must have the same domain.

End of the note.

You can find information on search rules and conversion rules in Rules .

  • Database tables : A database table contains information from a discrete area. This information is stored in table-form. In CAPP you can take data from database tables for the following master data or objects for determining characteristics.

  • Material master

  • BOM

  • Task list header

  • Operation

  • Material component allocation

You can find further information on search rules and conversion rules in the section Rules.

( )

In CAPP you can specify the name of a field in a table from which the value of a characteristic in a formula is to be determined.

Note Note

You can only specify fields in the function section of the table as the characteristic origin. Key fields in a table cannot be specified as the characteristic origin.

End of the note.

All the characteristics from the formula and the key fields are listed in method maintenance. You can enter a rule in method maintenance for each of the characteristics generated for the key fields.
