  • What causes this issue?

    The number of iteration steps in BOM processing exceeded the defined
    maximum.

    System Response

    The iteration is terminated, and the message is raised.

    How to fix this error?

    If the number of iterations exceeds the defined maximum number of steps,
    there is one of the following reasons:
    There is a recursion in the data
    The selection range is too big
    In the second case please limit the selection conditions further, so
    that the error does not occur any more.
    In most cases, the flag for stock transfer is marked and the considered
    plants and work centers to be included from stock transfer are too
    large, e.g. since the considered plants range is empty, which means all
    plants in the system are taken. Then you need to narrow down these
    parameters.

    Causes:
    
    Data Issues: Inconsistent or incorrect master data (e.g., material master, BOM, routing) can lead to planning failures.
    Configuration Problems: Incorrect settings in the planning parameters or planning strategy can cause the algorithm to struggle to find a solution.
    Complex Planning Scenarios: Highly complex scenarios with many constraints or dependencies may require more iterations than allowed.
    Resource Constraints: Limited capacity or resource availability can lead to planning conflicts that prevent convergence.
    Parameter Settings: The maximum number of iterations is
