Sequenced Across Tables is an abstract Concept Class used for organizational purposes. It cannot be instantiated in the model. It represents all sequenced table contexts.

Summary

The Sequenced Across Tables contexts look for a sequence of anchors, facts, skips, tables, where the fact and anchor elements must be in separate segments.

List of Sequenced Across Tables Contexts

Usage Notes

These are contexts that use a sequence rule to identify the table. They are used in sequences with Table Property Contexts to extract tabular data.
