In Smart Reference Data, a specification rule allows you to assign tables and attributes on the specification header and the specification item level. The specification rules are defined on the S.50.01 Specification Rules screen, found in the S.50 Specification branch underneath Smart Reference Data in the menu tree.
As described in the first section t, a specification header provides descriptive information. Most of the information, such as general material, can be assigned by Smart Reference Data table details (similar to commodity attribute table), defined on A.50.02 Tables. The specification rule allows you to use any table type defined on A.50.02. Only the tables assigned to the specification header (HEADER) can be used later for the detailed description of the specification at the header level.
This example allows you to assign table details to each specification based on the following tables: p_service, p_rating_class, p_temp_limit, p_corr_allowance, p_material_type, and so forth.
In the third (Attributes) block on the S.50.01 screen, attributes are assigned to the specification header and specification line items. Both types of assignments are used for further documentation, reports, or for CIP execution in downstream Smart Materials modules. There is one special attribute that can be assigned to the spec items, the hard-coded attribute "ASS_NO.," which is used for the creation of spec-dependent assemblies.
