Circular references are not allowed in BOM Formula

(0) ShareShare

Posted on by Michael Antony 314

Hi friend, my name is Antony.
I have been trying to create formula (BOM) inside of product in AX365. But i always get this error message 'Circular references are not allowed' whenever i do the check function.

I already set the product production type to 'none' for the Raw Material inside the formula lines. And production type to 'formula' for the Finished Good product. Yet i still get the same warning of 'Circularity references is not allowed'. I don't understand what I am doing wrong. Any suggestions how to resolve this?

For added information, i set the circularity check to 'Lines' in the BOM parameter in Inventory Management.

    Hi Michael Antony,

    Circular reference means that there is a formula item which is added as a sub formula of its child example:

    C is added as sub formula to B and B is added as sub formula item to A and A is added as Sub formula item to C. This creates a circularity and can cause infinite loops when processing Formulas.

    That is why you are getting Circularity error.

    Hi Sumit Loya,

    Thank you for your input. But the item that i added as formula component of the main item doesn't have formula, it's just pure raw material item.

    That's why i don't know where the circularity might be happening.

    Regards,

    Antony

    Did you check BOM for raw material. Are you creating new BOM (IF You are updating old BOM, ıt is possible that the problem come from old line records)

    Thanks for the input friend. It turns out that a modification to the BOMHierarchyCheck class that I migrated from AX2012, which makes the check function in the formula/BOM result in always having a circular reference.
