How To Fix DBMAN309 - Missing mapping for characteristic &1 of InfoProvider &2

SAP Error Message - Details

• Message type: E = Error

• Message class: DBMAN - Data Manager Message Class

• Message number: 309

• Message text: Missing mapping for characteristic &1 of InfoProvider &2

What causes this issue?

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.

System Response

The query cannot be generated.

How to fix this error?

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.

  The SAP error message DBMAN309 indicates that there is a missing mapping for a characteristic in an InfoProvider. This typically occurs in the context of SAP BW (Business Warehouse) when there is an inconsistency between the data model and the data being processed.
  Cause:
  
  Missing Characteristic Mapping: The characteristic specified in the error message is not mapped correctly in the InfoProvider. This can happen if the characteristic was removed or not included in the data model.
  Data Source Changes: If the underlying data source has changed (e.g., fields were added or removed), the InfoProvider may not be able to find the necessary mappings.
  Inconsistent Data Model: Changes in the InfoObject or InfoProvider structure that have not been properly reflected in the data model can lead to this error.
  Transport Issues: If changes were transported from one system to another (e.g., from development to production) without proper adjustments, it may lead to missing mappings.
  
  Solution:
  
  Check Characteristic Mapping: Go to the InfoProvider definition and verify that the characteristic mentioned in the error message is correctly mapped. Ensure that it exists in the data model.
  Update Data Source: If the data source has changed, update the InfoProvider to reflect these changes. This may involve modifying the transformation rules or the data source settings.
  Re-activate InfoProvider: Sometimes, simply re-activating the InfoProvider can resolve mapping issues. This can be done in the SAP BW modeling tools.
  Check for Transport Issues: If the issue arose after a transport, check the transport logs and ensure that all necessary objects were transported correctly.
  Data Load Monitoring: Monitor the data load process to identify if there are any other related errors that could provide more context on the issue.
  Consult Documentation: Review SAP documentation or notes related to the specific InfoProvider and characteristics to ensure compliance with best practices.
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like RSA1 (Data Warehousing Workbench) to access InfoProviders and check their settings.
  SAP Notes: Search for relevant SAP Notes in the SAP Support Portal that may address specific issues related to DBMAN309.
  Data Modeling: Familiarize yourself with data modeling concepts in SAP BW, including InfoObjects, InfoProviders, and transformations, to better understand how mappings work.
