  • What causes this issue?

    In this query, input-ready formula '&V1& &V2&' is used. The system uses
    inverse formulas on basis key figures to back-calculate entries in
    formulas like this. The inverse formulas required for this are defined
    in Query Designer. The inverse formula that the system selects depends
    on the status of the operands in the inverse formulas. The following
    operand statuses are possible:

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

    An operand has been entered
    An operand has been fixed
    An operand has already been calculated by another formula
    An operand is not input-ready.
    The system now searches for an inverse formula that as many operands as
    possible have been defined for. If this selection is not unique, the
    inverse formula with the highest priority wins. During this process, a
    formula group can only be calculated once. If no inverse formulas are
    found, the system displays this message.

    System Response

    The entries cannot be processed.

    How to fix this error?

    Check the entries or fixed cells.
    Enter fewer values
    Revoke any fixing of cell values
    The following messages list which operands go into input-ready key
    figure '&V1& &V2&' and which status these operands have (entered,
    calculated, fixed, not input-ready).

  • What is the cause and solution for SAP error message BRAIN581 - Input-ready formula '&1 &2' cannot be inverted ?
    The SAP error message BRAIN581 indicates that there is an issue with an input-ready formula in SAP BW (Business Warehouse) or SAP BPC (Business Planning and Consolidation). Specifically, the error states that the formula cannot be inverted, which typically means that the formula is not structured in a way that allows for the calculation to be reversed or solved for a specific variable.
    
    Cause: Formula Structure: The formula may be incorrectly structured or may contain elements that do not allow for inversion. For example, if the formula involves division by a variable that can be zero, it cannot be inverted. Circular References: The formula might create a circular reference, where the output depends on itself, making it impossible to calculate. Data Type Issues: There may be data type mismatches or incompatible operations within the formula. Missing Variables: The formula may reference variables that are not available or not defined in the context of the calculation.
