SAPM_SO Procurement Modell no Business Partner ID

Hello,

For a new Demo I need to create a new order in transaction SAPM_SO but I cant find any Business Partner Data. After creating a new customer data in XD01 no Business Partner ID Data in SAPM_SO can be found.

I tried to maintain data in der table SNWD_CONTACT but it cant be modified.

Any suggestions?

Thanks a lot

Michael
