S4 Hana Contact person mapping during migration.

Hi,

We are following conversion guide for migration. In this guide in scetion 5.2.2.2.1Prepare Customizing and Mapping Tables for Business Partner Conversion, it is mentioned that

13.

For Contact Person Mapping

In transaction SE 11, ensure that you maintain in mapping tables, CVI_CUST_CT_LINK and CVI_VEND_CT_LINK, the same number of entries as in customer table KNVK with the condition KNVK with where condition KUNNR <> SPACE and KNVK with where condition LIFNR <> SPACE.

We are quite unsure on maintaining tables in SE11? Can anybody explain us what is meant by this and how do we get ovet shis?

Regards

Shiva
