In SAP Cloud Identity Services, transformation variables are used to save data temporarily during data transformation processes. These variables act as placeholders to store intermediate values, such as user attributes or calculated fields, while processing data between source and target systems in identity provisioning. Temporary storage enables complex transformations, like mapping or reformatting data, without affecting the final output until the transformation is complete. Transformation variables are not used to save data to the output JSON file, as this is handled by the transformation rules’ final output configuration. Similarly, they do not save data permanently, as their scope is limited to the transformation process, and permanent storage would occur in the target system’s repository. By using transformation variables for temporary data storage, SAP Cloud Identity Services ensures flexible and efficient data handling, supporting seamless integration and customization of identity data flows while maintaining security and accuracy in provisioning processes.
