How To Fix UCT8252 - Cannot derive the source selection from target field &1

SAP Error Message - Details

• Message type: E = Error

• Message class: UCT8 - Message class for UCT8(mapping)

• Message number: 252

• Message text: Cannot derive the source selection from target field &1

What causes this issue?

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 usually
derives 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.

How to fix this error?

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 not
process a large amount of data, and that system performance was not
satisfactory, you may want to examine the source selection by choosing
the <LS>Source</> button in the log. If the reason for the disregarded
data is that too much source data was read because of the unrestricted
selection 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 via
mapping to the target field &V1&.
