This document provides instructions for building ADaM basic data structures (BDS) from annotated mock up tables. It discusses how to design mock up tables based on the statistical analysis plan, annotate the tables, create metadata, and then build the ADaM BDS datasets according to the metadata. The process results in analysis-ready ADaM datasets where all numbers in the final report can be calculated with one SAS procedure. An example is provided demonstrating how to annotate a mock up table and extract the necessary variables and parameters to include in the ADaM datasets and metadata.
