  The SAP error message CM_REPORT_TEMPLATE123 indicates a nesting error in a report template, specifically related to the ELSE branch of a conditional statement in the report layout. This error typically arises when the structure of the report template is not correctly defined, leading to issues with how the report processes conditional logic.
  Cause:
  
  Incorrect Nesting of Conditional Statements: The error often occurs when the ELSE branch of a conditional statement is not properly aligned with its corresponding IF statement. This can happen if there are missing or extra start or end symbols in the report template.
