SAP Message UCT8252 - Cannot derive the source selection from target field &1

Diagnosis
Field &V1& has one of the following roles:

  • Consolidation unit

  • Group currency key

  • Fiscal year

  • Posting period

  • Version

    • To delimit the volume of the source data to be read, the system usuallyderives the source selection from the target selection of such a field.However, the system cannot derive a source selection from field &V1&.

    System Response
    It is possible that a greater volume of source data is being read than i
    s necessary. This can lead to performance issues.

    Procedure
    Check whether a mapping rule is defined for field &V1&.
    If a mapping rule is defined, you can disregard this warning message.
    However, if you discover after method execution that the system did notprocess a large amount of data, and that system performance was notsatisfactory, you may want to examine the source selection by choosingthe Source button in the log. If the reason for the disregardeddata is that too much source data was read because of the unrestrictedselection on the source field (which is linked with target field &V1&through mapping), choose one of the alternatives below:

    • Change the mapping rule for field &V1& so that the system can derive a
      • delimiting source selection.
      • Implement the Business Add-In (BAdI) UC_DATATRANSFER with the method INV

        • ERT to delimit the selection for the source field that is linked viamapping to the target field &V1&.
