Unable to Assign the supplier to operating unit

HI,

We have Supplier A Who is assigned to 2 operating Units. When we want to add the same supplier to another operating unit-B it is throwing the below error:

Address and Site Creation - Unable to create address and sites because of the following error when trying to create the site in operating unit B [ORA-01403: no data found in Package AP_VENDOR_PUB_PKG Procedure Validate_Vendor_Site]. Either resolve this issue and try again or deselect the operating unit with the error and continue. Note: any new address requires at least one site in order to be created.
