How To Fix CNV_CMIS_M034 - This rule type may only have one mapping value

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_CMIS_M - Message class for CMIS Migration

• Message number: 034

• Message text: This rule type may only have one mapping value

What causes this issue?

Rules that are related to either the "<ZH>LOGSYS</>" or "<ZH>MANDT</>"
<ZH> </>are restricted to one mapping value. The relationship is
defined by the name of the rule. When either the word<ZH> </>"<ZH>LOGSYS
</>" or "<ZH>MANDT</>" appears then this check occurs.
There is a risk, of course, that the names are altered and then the
check is skipped. If we are dealing with either a logical system
(LOGSYS) or a client (MANDT), ensure that this does not occur.
