         <BusinessPartner/>
           .

          <BusinessPartner/>
          <BPIdentificationType>YYYYYY</BPIdentificationType>
          <BPIdentificationNumber/>
          </A_BuPaIdentificationType>
          </to_BuPaIdentification>
   
   
3. The system throws the error : "Enter ID Number"

         Note:
         In the above example:
         xxxxxx represents the tenant URL of the system
         YYYYYY represents the Identification type of the Business Partner

The error occurs because the BP Identification number is missing in the request payload. 

According to the SAP standard process for Business Partners, the Identification number cannot be left blank as it is the primary key field in the BUT0ID table, sending this field blank would cause inconsistencies with other tables that are related to it. The Business Partner Identification number is a mandatory field and must be included in the request payload.
