WRF_AT_GENERATE102 - Details

• Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WRF_AT_GENERATE102 Allocation table type &1 is not one-level and is therefore not allowed
  
  
  Cause:
  This error occurs during the generation or processing of allocation tables (used in cost allocation, settlement, or similar processes) when the allocation table type specified is not a one-level type. SAP requires the allocation table type to be one-level for certain operations, but the provided allocation table type is multi-level or hierarchical, which is not supported in this context.
  
  Allocation table types in SAP define the structure of the allocation table.
  One-level allocation table means the table has a flat structure without hierarchical or multi-level dependencies.
  If the allocation table type is multi-level (e.g., contains sub-levels or hierarchical nodes), the system cannot process it in the current operation, leading to this error.
  
  
  When does it occur?
  
  During the generation of allocation tables in cost allocation or settlement processes.
  When using transaction codes or
