cdisc-core-sas

The cdisc-core-sas GitHub repository contains working files and other artefacts to support a Proof of Concept for running CDISC CORE within SAS.

This Proof of Concepts is based on CORE release v0.8.1 (September 24, 2024) and was developed on Windows 10 with SAS 9.4 TS1M7.

Supported python versions

Installing dependencies

These steps should be run before running the SAS programs.

• Create a local copy of the lexjansen/cdisc-core-sas GitHub repo:

  git clone https://github.com/lexjansen/cdisc-core-sas.git

• Create a virtual environment in your copy of the lexjansen/cdisc-core-sas repo:

  python -m venv <virtual_environment_name>

• Activate the virtual environment:

  .\<virtual_environment_name>\Scripts\Activate -- on windows

• Install the requirements.

python -m pip install -r requirements.txt # From the root directory

Environment variables

Define the following OS environment variables:

• CORE_PATH - Location of the local cdisc-rules-engine local repo clone
• CDISC_LIBRARY_API_KEY - CDISC Library API Key for updating the rules cache

Alternatively, the CDISC_LIBRARY_API_KEY variable can be set in programs/options.sas or in the core_update_cache macro call.

Run SAS programs

Check the options in programs/options.sas to be able to run Python:

options set = MAS_PYPATH = "&project_folder/.venv/Scripts/python.exe";
options set = MAS_M2PATH = "%sysget(SASROOT)/tkmas/sasmisc/mas2py.py";

Run the following SAS programs (make sure to update the project_folder macro variable in each program):

• programs/create_core_functions.sas (creates the core_funcs dataset in macros)
• programs/run_core_update_cache.sas (updates the cache in resources\cache)

After this all the other SAS programs can run:

• programs/run_core_list_ct.sas
• programs/run_core_list_dataset_metadata.sas
• programs/run_core_list_rules.sas
• programs/run_core_list_rule_sets.sas
• programs/run_core_validate_data.sas
• programs/run_core_validate_data_select.sas
