SAP Message UCT8002 - Mapping rule for &1, row &2: Source field &3 does not exist

Diagnosis
The mapping rule for target field &V1& uses the source field &V3& in row
V2. however, source field v3 is not in the list of sourcefields. This error can have the following causes:

  • The data type originally defined in method Customizing was changed
  • afterwards (after mapping was defined). This made the source fieldinvalid.
    • The source data basis originally defined in method Customizing was
    • changed afterwards. The original source field exists, but not inthe new source data basis.
      • The source data basis was changed afterwards - for example, it points to
      • a different InfoProvider or InfoObject catalog that does notcontain the original source field.

        System Response
        The settings cannot be saved. The system issues an error message.

        Procedure
        Do one of the following:

        • Choose an existing source field.

        • Check that the source data basis is defined correctly and (if
        • applicable) switch to another source data basis.
