Firstly, do the partner determination for contact persons in VOPA, maintain contact persons (CP) as partners and assign them to the account group.
Then, define the contact person using transaction code (XD01) and choose the account group for contact persons. After you have defined the contact person and the system has generated a number for the contact person, Go to (XD02) and enter the customer number to which you would like to assign the contact person. Go to the Partner function tab page and enter the Partner function CP and the number for the contact person that was generated when you defined the contact person.
Points to note:
The contact persons are maintained in standard SAP under partner function CP and are defined under partner type AP.
In the customer master if you wish to include contact persons, you need to create some contact persons first. You can do that by using t code VAP1 and specifying the customer for whom this contact person is required.
After this, if you go to the master data of the customer, in the contact person tab, you will find this contact person if you scroll down.
When you create a sales order for this customer, in the partners tab, this contact person will also be reflected.
