SAP Message C$726 - Repeating group && contains symbols with different expansion fences

Diagnosis
Repeating group &V1&&V2& contains symbols that feature differentexpansion time points.
A repeating group should only contain symbols that feature identicalexpansion time points (either specification data or parameters). If arepeating group contains both symbols that reference the specificationdatabase as well as parameter symbols, this may cause problems duringmultilevel report generation. If you only need one generation run togenerate the final report from the template, no problems should occur.

System Response
The system logs a warning message since it cannot determine whether thetemplate is used for multilevel report generation.

Procedure
Check whether your symbol assignment to repeating group &V1&&V2& iscorrect.
