  The SAP error message AQQV182 indicates that there is an issue with the logical database being used in your ABAP program or report. Specifically, the error states that the root node of the logical database is not of type "T" (table) or type "S" (structure). This typically occurs when the logical database is not correctly defined or when the program is trying to access a logical database that does not conform to the expected structure.
  Cause:
  
  Incorrect Logical Database Definition: The logical database may not be defined correctly in the ABAP Dictionary (SE11).
  Wrong Root Node: The root node of the logical database might not be set to a valid type (T or S).
  Program Configuration: The ABAP program may be incorrectly configured to use a logical database that does not match the expected structure.
  Changes in Data Model: If there have been changes in the underlying data model or database tables, the logical database may need to be updated accordingly.
