• Message class: WRF_APC - Messages for Operational Assortment Planning and Control

• Message number: 132

• Message text: Enter hierarchy node manually, no default node can be determined

What causes this issue?

The system could not determine a default hierarchy node for the planned
material because:
The node assigned to the purchasing list is not an end node.
There are several end nodes below the node assigned to the purchasing
list.

• What is the cause and solution for SAP error message WRF_APC132 - Enter hierarchy node manually, no default node can be determined ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WRF_APC132 - Enter hierarchy node manually, no default node can be determined
  
  Cause:
  This error occurs in SAP when the system is unable to automatically determine a default hierarchy node during a process that requires one. Typically, this happens in the context of APC (Activity Price Calculation) or costing where a hierarchy node is expected to be assigned or derived automatically, but the system finds no suitable default node based on the current master data or configuration.
  Common scenarios include:
  
  Missing or incomplete hierarchy assignments in the master data (e.g., cost center hierarchies, work center hierarchies).
  The hierarchy node is not maintained or assigned in the relevant customizing or master data.
  The system cannot find a default node because multiple nodes exist but no default is flagged.
  The relevant hierarchy is not properly activated or assigned in the controlling area or plant.
  
  
  Solution:
  To resolve this error, you need to ensure that the system can determine a default hierarchy node or that the user manually enters one. Steps include:
  
  
  Check Hierarchy Setup:
  
  Verify that the hierarchy nodes are correctly maintained in the relevant hierarchy (e.g., cost center hierarchy, work center hierarchy).
  Use transaction codes like KSH1 (Create Cost Center Hierarchy), KSH2 (Change), or KSH3 (Display) to check the hierarchy nodes.
  Ensure that the hierarchy is active and assigned to the controlling area or plant.
  
  
  
  Assign Default Node:
  
  If multiple nodes exist, assign a default node or flag one as default if the system supports it.
  Check customizing settings in SPRO under Controlling > Cost Center Accounting > Master Data > Maintain Hierarchy.
  
  
  
  Maintain Master Data:
  
  Ensure that the master data objects (cost centers, work centers, etc.) are assigned to the correct hierarchy nodes.
  For example, check the assignment of cost centers to hierarchy nodes.
  
  
  
  Manual Entry:
  
  If the system cannot determine a default node, the user must manually enter the hierarchy node during the transaction or process.
  The error message prompts the user to input the node manually.
  
  
  
  Check Authorizations:
  
  Sometimes, missing authorizations can prevent the system from reading hierarchy data properly.
  
  
  
  Review Customizing for APC:
  
  In the context of Activity Price Calculation, check the settings under Controlling > Product Cost Controlling > Cost Object Controlling > Activity Price Calculation.
  Ensure that the hierarchy nodes required for APC are properly maintained.

  Summary:
  The error WRF_APC132 indicates that the system cannot find a default hierarchy node and requires manual input. The root cause is usually missing or incomplete hierarchy assignments or configuration. The solution involves verifying and maintaining the hierarchy nodes and their assignments, ensuring defaults are set, and entering the node manually if needed.
