• What is the cause and solution for SAP error message WRF_AT_GENERATE102 - Allocation table type &1 is not one-level and is therefore not allowed ?

  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 programs that expect a one-level allocation table type but receive a multi-level type.
  Possibly during custom developments or enhancements where allocation table types are specified.
  
  
  Solution:
  
  
  Check the Allocation Table Type:
  
  Verify the allocation table type used in the process.
  Use transaction KSU3 (Maintain Allocation Table Types) or relevant IMG settings to check the characteristics of the allocation table type.
  
  
  
  Use a One-Level Allocation Table Type:
  
  Change the allocation table type to one that is defined as one-level.
  If a multi-level allocation table type is being used, switch to a one-level type compatible with the process.
  
  
  
  Adjust Custom Code or Configuration:
  
  If this error arises from custom code or user exits, ensure that the allocation table type passed is one-level.
  Modify the code or configuration to select or generate allocation tables with one-level types.
  
  
  
  Consult SAP Documentation or Notes:
  
  Check SAP Notes related to allocation tables and this error message for any patches or updates.
  Sometimes, SAP releases corrections or clarifications for allocation table handling.
