ax 2012 - BOM Lines form very slow on closure ( more than 10minutes )

Hi,

i'm experiencing high delays with some released products.

When i close the BOM lines for a certain product, ax starts processing and it takes up to 10minutes to get the program ready again.

I noticed it makes a call to BOMConsistOf.checkBOM() method, which is sort of a check for circularity in BOM lines. Can this be avoided somehow (by parameters, or whatever)?

I have similar issues when i release a production order, can this be related somehow?

thank you in advance

regards
