How To Fix KI529 - Iteration convergence is extremely slow in the loop displayed

KI529 - Overview

• Message type: E = Error

• Message class: KI -

• Message number: 529

• Message text: Iteration convergence is extremely slow in the loop displayed

What causes this issue?

The SAP System could find no loop that caused termination. In the
iteration relationships, however, is a loop in which values to be
iterated are allocated for a long time in circles. The iteration thus
converges very slowly.

System Response

The iteration may terminate after a certain number of iteration steps
due to the slowness of the convergence.

How to fix this error?

If iteration terminates you have the following options.
Rework the sender-receiver relationships.
Let the iteration run in the background with more iteration steps
allowed.

• What is the cause and solution for SAP error message KI529 - Iteration convergence is extremely slow in the loop displayed ?

  The SAP error message KI529, which indicates that "Iteration convergence is extremely slow in the loop displayed," typically occurs in the context of cost planning or cost allocation processes within SAP Controlling (CO). This error suggests that the system is having difficulty converging on a solution during iterative calculations, which can happen for several reasons.
  Causes:
  
  Complexity of the Model: The cost allocation model may be too complex, with many interdependencies that make it difficult for the system to find a solution.
  Data Issues: There may be issues with the data being used in the calculations, such as missing or incorrect entries, which can lead to slow convergence.
  High Volume of Data: A large volume of data or a high number of cost centers can slow down the iteration process.
  
  Configuration Issues: Incorrect configuration settings in the cost planning or allocation process can lead to inefficiencies in the calculations.
  Circular References: If there are circular references
