The creation of a data map is one piece of information that would assist in satisfying the supervisory authorities' request for records of the processing operations within an organization.
Data maps can also play a significant role in Article 6. According to GDPR, every instance of processing personal data must have a lawful basis. Organizations must determine which reason for processing applies, inform consumers of it as part of their privacy policy or other disclosures, and make sure that the necessary paperwork is produced. This is significantly more challenging if they do not maintain a list, or "map," of all of their processing. It is also simpler for businesses to defend their processing or decide that it needs to be modified after a list of processing has been created.
The purposes of the processing, the categories of personal data involved, the categories of recipients, any transfers of personal data to a third country or an international organization, the duration of data retention for each category, and, if possible, a general outline of the technical and organizational security measures in place must all be documented by data controllers.
Any transfers to a third country or international organization must include documentation of the appropriate safeguards in place, and processors must keep records of the contact information for each controller, the categories of processing carried out for the processor, any such transfers to a third country or international organization, and a general description of the technical and organizational security measures used.

Describe the information flow after that. To find unplanned or unintended applications of data, go through the information lifecycle. Ensure that the information's users are consulted on any practical implications. Even if they are not immediately required, think about how the information collected may be used in the future. This process additionally helps to lessen the amount of data that is collected.

The supporting resources utilized to process personal data should then be included. Identify the hardware, software, or processes that are utilized to process personal data.
To illustrate the data flow between assets, add data transfers after adding your supporting assets. Mark the direction of data flow between assets, specifying the types of data that are exchanged and the means by which they are done.
Review the procedure to complete your map. View and print reports to share with stakeholders. Every time a process modification is made, update the process map and specifics.
