How To Fix UCT8253 - Inversion of the mapping rule for &1 is possibly incorrect

UCT8253 - Overview

• Message type: E = Error

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

• Message number: 253

• Message text: Inversion of the mapping rule for &1 is possibly incorrect

What causes this issue?

&V1& is a status-relevant field. The mapping rule cannot be reversed
unambiguously. Therefore, the system is unable to uniquely identify the
source selection condition. Thus, great volumes of data are selected,
which can cause the task to run considerably longer.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

The following changes in the mapping operator can remedy this problem:
Reduce the number of source fields that are connected to each other.
Enter the length for each source field and deselect the <ZK>Trim
Marginal Spaces </>indicator.
Note that this is only a warning. You can still use the mapping rule.
