Employee BP Vendor BP integration in S4hana

[Imran-FI]

Issue after conversion activity in S4 Employee BP sync report:

In our case some employees in ECC system has business partners (created with custom report) and also has venders. During CVI all venders converted to BP with same number.

Now after conversion getting error in Employee BP sync report as screenshot shared below. 

My query is: we have found 2 solutions from sap note,

2578294 - FAQ - Employee to Business Partner synchronization in S/4HANA OnPremise

1. Message R1477 "Number XXXXXXXX is already assigned to partner XXXXXXXXXX for ID type HCM001"

There are two possible solutions to fix this inconsistency:

- Delete the Business Partner completely. The sync report will generate a new Business Partner.

- Manually create the link between Central Person and Business Partner in table HRP1001 via transaction PP01. Before taking this action, you must change the customizing in table T777E to be able to modify relationship 209 in standard transactions

Question:

I have tried to apply 2nd solution but not working kindly guide me exact steps.

And if I go for BP deletion I need guidance for how I can delete Employee BP.
