CVI mapping errors returncode 12

Hello again!

I am configuring the CVI for migration of customers and vendors into business partners.

I am stuck with some remaining errors in the following tables: CVI_CUST_CT_LINK, CVI_VEND_CT_LINK, CVI_CUST_LINK, CVI_VEND_LINK and CVI_CUST_LINK.

I can not access these tables via SM30.

Where do I find these configs in spro?

Thanks in advance!

Best regards,

Karin
