How To Fix MPE_INSTALLATION_MSG020 - Different networks of same project have different parameter eff. value

MPE_INSTALLATION_MSG020 - Overview

• Message type: E = Error

• Message class: MPE_INSTALLATION_MSG -

• Message number: 020

• Message text: Different networks of same project have different parameter eff. value

What causes this issue?

You have specified different parameter effectivity values for the
networks of the same WBS element.

System Response

MRP cannot separate demand that has different parameter effectivity
values. MRP can separate demand for different end-item units and explode
the BOM correctly only if demand with different parameter effectivity
values also has different WBS elements.

How to fix this error?

Change the model/unit of the network using transaction <AB>CJ20N</>.

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message MPE_INSTALLATION_MSG020 - Different networks of same project have different parameter eff. value ?

  The SAP error message MPE_INSTALLATION_MSG020 indicates that there is a discrepancy in the effective parameter values across different networks within the same project. This typically occurs in the context of project management or network planning in SAP, where different networks (or activities) are expected to have consistent parameter settings.
  
  Cause:
  The error arises when:
  
  Different networks within the same project have been assigned different effective values for the same parameters.
  This inconsistency can occur due to manual changes, data imports, or configuration settings that were not uniformly applied across all networks.
  
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Identify the Networks: Determine which networks are causing the issue. You can do this by reviewing the project structure and the parameters assigned to each network.
  
  
  Check Parameter Settings: For each network, check the effective parameter values. You can do this by navigating to the network details in the project management module.
  
  
  Standardize Parameter Values: Ensure that the
