How To Fix BRAIN568 - Inverse formula is missing for &2 for input-ready formula &1

BRAIN568 - Overview

• Message type: E = Error

• Message class: BRAIN -

• Message number: 568

• Message text: Inverse formula is missing for &2 for input-ready formula &1

What causes this issue?

In a formula group, inverse formulas must be defined for all modifiable
elements. This means all elements that are input ready or a formula with
input-ready parts. This is not the case for this formula group, as
element &V2& in formula group &V1& is modifiable, but the inverse
formula for &V2& is missing.

System Response

The query contains errors and cannot be generated.

How to fix this error?

If &V2& is input-ready, create an inverse formula for &V2&. Otherwise,
make &V2& input-ready too or revoke the input-readiness of of the
operands for &V2& .

BRAIN568 - Details

• The SAP error message BRAIN568 indicates that there is an issue with an input-ready formula in SAP BW (Business Warehouse) or SAP BPC (Business Planning and Consolidation). Specifically, it means that the inverse formula for a given input-ready formula is missing. This can occur when you are trying to use an input-ready formula that requires an inverse calculation, but the system cannot find the corresponding inverse formula.
  
  Cause:
  
  Missing Inverse Formula: The primary cause of this error is that the inverse formula has not been defined in the system for the specified input-ready formula.
  
  Configuration Issues: There may be configuration issues in the planning model or the formula setup that prevent the inverse formula from being recognized.
  Data Model Changes: Changes in the data model or the underlying InfoObjects may have led to the removal or misconfiguration of the inverse formula.
  
  
  Solution:
  
  
  Define the Inverse Formula: 
  
  Go to the planning model where the input-ready formula is
