Customer is not assigned to a partner function

Question

Hi Experts,
I'm encountering the same error. When I view the Customer and click Customer Partner Functions, system throws a message Customer SP0003 is not assigned to a partner function
How do I assign my newly created Customer to a Partner Function Sold-to-Party?
I've checked the setup for Partner Determination: Customer Master, the settings are as follows:
Partner Determination Procedures:
AG Sold-To Party
IN Sales Prospect
KO Consumer
RE Bill-to Party
RG Payer
SO Assortment cust.
WE Ship-to party
WESR GR w/ MatSafSheetRec
Partner Functions in Procedure:
AG SP Sold-to party NotModifiabe, Mandatory
AG BP Bill-to party Mandatory
AG PY Payer Mandatory
AG SH Ship-to party Mandatory
Partner Determination Procedure Assignment:
Account Group YG01 (account group of new Customer) assigned to AG (Sold-to-Party)
Account Groups - Function Assignment:
SP Sold-to party YG01 Customer BP
Is there any other config I should do?

Answer 1

Go to IMG path -- SD --> Basic Functions --> Partner Determination --> Setup Partner Determination --> Set Up Partner Determination for Customer Master. 
-  There block "AG Sold To Party" and double click on "Partner Functions in Procedure".
-  Ensure that for AG, you have maintained SP and the box Mandatory is checked.
-  Block AG/SP and double click on "Partner Determination Procedure Assignment" and see for Group 0001, AG is assigned
-  Click on "Partner Functions" and see for SP, KU is maintained under the tab Partner Type and the box is checked
-  Click on Account Groups-Function Assignment.  Here ensure that the Account Group are assigned to your SP.
thanks
