In Treasury and Risk Management, only organizations and groups are
permitted as business partners in financial transactions.
Note:

The financial transactions portrayed in TRM are B2B transactions between
your company and banks, financial institutions, brokers, or similar
institutions. Likewise, the master data required for the processes in
TRM relate to companies and financial institutions. Consequently, the
simplified blocking and deletion of personal data using <LS>SAP
Information Lifecycle Management</> (SAP ILM) is not implemented.

If you use <LS>Treasury and Risk Management</> to portray financial
transactions with natural persons, for example, or your usage of

ways, you need to deploy separate supplementary technical and
organizational measures to ensure that you respect the deadlines

TI031 - Details

• The SAP error message TI031 indicates that you are trying to assign a business partner (BP) that is classified as a natural person to a context or role that is not compatible with natural persons. This typically occurs in scenarios where the system expects a business partner to be a legal entity (such as a company) rather than an individual.
  
  Cause:
  
  Business Partner Classification: The business partner you are trying to assign is classified as a "natural person" (individual) in the system.
  Role Compatibility: The role or context you are trying to assign the business partner to may only be compatible with legal entities (e.g., companies, organizations) and not with natural persons.
  
  Configuration Issues: There may be configuration settings in the SAP system that restrict certain roles to only legal entities.
  
  
  Solution:
  
  Check Business Partner Type: Verify the classification of the business partner in question. You can do this by navigating to the Business Partner transaction
