Before we can start to create piping specifications, we must define the specification types and rules.
The specification type can be used to categorize and organize the specifications; for example, company departments, plant types, main specification material, media, and other information.
The specification types are defined on the S.50.02 Specification Types screen, found in the S.50 Specification branch underneath Smart Reference Data in the menu tree.
Each specification type is assigned to a specification rule. At least one rule must exist before a specification type can be created.
If you want to use the specification copy function, you must define the specification type structure. On S.50.05 Specification Copy, only those specifications that can be selected as source specifications are shown in the second block. These specifications are assigned to the spec type of the spec defined as destination in the first block. If no spec type exists in the second block of the S.50.02 screen, the specification copy function is not available within this specification type.
