CVI_VEND_LINK table — Business Partner to Supplier Link
CVI_VEND_LINK stores the technical relationship between a Business Partner and its synchronized supplier or vendor number. It is a primary CVI diagnostic anchor when a BP exists but the supplier representation is missing or inconsistent. The mapping proves identity linkage, while company-code and purchasing-organization completeness must still be verified in the corresponding supplier data.

What it stores
CVI_VEND_LINK stores the technical mapping between a Business Partner GUID and its synchronized supplier or vendor number. Each row must be interpreted using the complete technical key and the application process that writes it. A consultant should first establish whether the row represents current state, a dated master-data slice, a document item, a history event, an index entry or a compatibility representation. Organizational levels, validity dates, fiscal years, ledgers, languages, statuses and sequence numbers are part of the grain whenever those dimensions exist. The table should be read as evidence of application behavior, not as an isolated spreadsheet. Confirm the owning business object and configuration before deciding that a value is wrong.
Key fields
The supplier-side CVI link identifies how a Business Partner corresponds to a vendor/supplier master identity. Partner and supplier numbering can differ when their number ranges and mapping rules are not shared.
- PARTNER_GUID — technical Business Partner GUID.
- VENDOR or supplier number — linked classic vendor identifier.
- BUT000 — resolves the BP identity.
- LFA1/LFB1/LFM1 — provide synchronized supplier segments.
- CVI synchronization logs and checks — determine mapping consistency.
How it joins the data model
Follow the configured BP-to-vendor mapping using the release-defined identifier columns. Validate the underlying supplier company-code and purchasing extensions separately; the CVI relationship alone does not make the supplier valid for every purchasing process.
- PARTNER_GUID to BUT000-PARTNER_GUID
- VENDOR to LFA1-LIFNR
- VENDOR to LFB1 and LFM1 for company-code and purchasing-organization extensions
How to read it safely
If a Business Partner has a supplier role but MIRO or ME21N cannot find the intended supplier, inspect CVI sync logs and the missing organizational views before changing identifiers. Never repair link records by direct SQL.
How to prove it in the data
Take one reproducible example from the relevant SAP screen, report or application log. Record its full displayed key, organizational context, key date, language and status. Locate the matching CVI_VEND_LINK row using those values, then follow the documented parent and child joins without dropping key components. Compare the result using the same key date and ledger. When values differ, test for leading-zero conversion, multiple validity slices, inactive history, parallel ledgers, fiscal-year boundaries, archived data and asynchronous replication. Save the read-only evidence before escalating. If the row is wrong, reproduce the maintenance path in a non-production system and route the fix to the application owner rather than changing the table.
ECC vs S/4HANA
CVI_VEND_LINK is central to S/4HANA supplier integration because Business Partner is the leading object. Use it with BP supplier roles and vendor tables to diagnose conversion and synchronization issues; do not repair inconsistent links with unsupported direct database updates.
Common pitfalls
- Selecting by one convenient identifier and silently mixing organizational units, years, ledgers, languages or validity periods.
- Joining on a partial key or descriptive value and creating duplicates that appear to be legitimate business rows.
- Ignoring inactive, deletion, reversal or status indicators and reporting retained history as current state.
- Assuming this table is authoritative without checking S/4HANA simplification, Business Partner synchronization, Universal Journal, MATDOC, CDS views or an external cloud source.
- Treating a missing row as proof that an event never occurred even though logging, replication, authorization and archiving scope can differ.
- Updating table rows directly instead of correcting data through the supported transaction, app, API or migration process.
Whose problem this is
Supplier master governance and procurement/FI own role and view completeness. CVI integration specialists investigate synchronization faults, with security ensuring the diagnosis does not expose protected data.
