• Message text: Conflict for non-transparent field &1 &2; &3 and &4 overlap

What causes this issue?

For the non-transparent field &V1& with value &V2& the two components
&V3& and &V4& have been evaluated. The intervals shown in brackets refer
to the character positions of the components in the non-transparent
field value. It has been detected that these components overlap.

System Response

The component &V4& is treated like it has not been found in the
non-transparent field.

How to fix this error?

Check the rules assigned to both components and correct the wrong one.
&HINTS&
If you determine that the overlapping is not problematic, you can switch
off conflict detection. If you do so, the component &V4& will be handled
the same way as if there was no conflict. To switch off conflict
detection, see the documentation for parameter ITR_CONFLICT_DETECTION in
transaction CNV_10020_PARAM.
