SAP Error Message - Details

• Message type: E = Error

• Message class: DBMAN - Data Manager Message Class

• Message number: 309

• Message text: Fehlendes Mapping für Merkmal &1 von Partprovider &2.

Was verursacht dieses Problem?

The MultiProvider contains the VirtualProvider P1 referred to in the
message.
Characteristic A for InfoProvider P1 in the MultiProvider, which was
also referred to in the message, is not mapped to a characteristic for
the MultiProvider.
This characteristic is either an attribute-bearing characteristic of a
mapped navigation attribute for the MultiProvider, or the InfoProvider
P1 of the MultiProvider does not support the navigation attribute. In
this case, the VirtualProvider interface requires a mapping of
characteristic A to a MultiProvider characteristic so that it can read
the required navigation attributes.
Alternatively, characteristic A is set as constant in InfoProvider P1 of
the MultiProvider or in the characteristic definition. In this case, the
VirtualProvider interface requires a mapping of characteristic A to a
MultiProvider characteristic so that it can check that the
VirtualProvider returned correct values for the constant characteristic
and so that it can filter them if required.

Systemantwort

The query cannot be generated.

Wie behebe ich diesen Fehler?

The problem can always be solved by changing the MultiProvider
definition. To do this, characteristic A needs to be mapped to a char
acteristic AX or navigation attribute X__AX of the MultiProvider that is
not used in the mapping with this InfoProvider P1 in the MultiProvider.
If there is no "free" characteristic AX in the MultiProvider, you can
create one as follows:
Create a referencing characteristic AR that contains the characteristic
A referred to in the message as the basic characteristic and then
activate characteristic AR.
Add characteristic AR to the MultiProvider as a master data provider
without completing a mapping for this InfoProvider AR of the Mu
ltiProvider.
Identify characteristic A for InfoProvider P1 of the MultiProvider that
was referred to in the error message with the MultiProvider
characteristic AR.
You can now generated the query.
