Hi Sumanth,

This is a common "gotcha" when transitioning logic from a background script to a Business Rule. The discrepancy usually happens because the background script queries the database directly, while the Business Rule interacts with the current object in memory during a transaction.

Look Up Select Box and Reference variables inherently store the sys_id at the database level. To fix this, you need to ensure your getVariableJSON function in the Script Include explicitly requests the display value.

Instead of just grabbing the variable's value, make sure you are using .getDisplayValue() on the specific element (e.g., current.variables.your_variable.getDisplayValue()). Also, double-check your Script Include's accessibility and ensure it is properly handling the static call CustomScriptInclude.getVariableJSON() if you aren't instantiating it with new in the Business Rule.
