How To Fix COM_PARTNER813 - Multiple mapping to partner function (&1) can lead to problems

COM_PARTNER813 - Overview

• Message type: E = Error

• Message class: COM_PARTNER - Partner Processing Messages

• Message number: 813

• Message text: Multiple mapping to partner function (&1) can lead to problems

What causes this issue?

Several partner functions are mapped to the R/3 partner role &V1&.
This can lead to problems with connecting the CRM System to the R/3
System:
If <ZH>two or more</> CRM partner functions that map to the <ZH>same</>
R/3 partner role are permitted in a partner procedure, in order that
these partner functions <ZH>may occur together</> in document entry (so
that the document is <ZH>not</>incorrect), copying this document into
the R/3 System would cause an error. R/3 can <ZH>only manage one
partner per partner role</>!
When copying master data or documents from R/3 into the CRM System, an
R/3 partner role can only be <ZH>uniquely</> mapped to a CRM partner
function. If several partner functions map to the same R/3 partner
role, this may cause problems when transporting data between an R/3 and
a CRM system (Example
<ZK>: </>partner functions Z1 and Z2 are both mapped to the partner
role SH. When transporting from R/3 into CRM, the partner role SH is
uniquely mapped to partner function Z1).

How to fix this error?

When working with both the CRM System and the R/3 System, you can only
choose <ZH>one</> CRM partner function in the CRM documents for each
R/3 partner function. This only affects documents that are copied into
the R/3 System. Pure activities are not affected by this restriction as
they are not copied into R/3.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
