In Smart Reference Data, a specification rule allows you to assign tables and attributes to the specification header and to specification items.
As described in the overview section of this document, a specification header offers a lot of describing information. Most of the describing information, such as general material, can be assigned by Smart Reference Data’ table details (identical to commodity code table) defined in A.50.02 Tables names. The specification rule allows you to use any table type defined in A.50.02.
Only the tables assigned to the specification header can be used later for detailed description of the specification at the specification header level.
The above example allows you to assign table details to each specification based on the tables service, rating class, material, and nominal corrosion allowance.
In the third block of Screen S.50.01, 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. This is the hard coded attribute "ASS_NO." which is used for the creation of spec dependent assemblies. Assemblies are not described in this document.
