Hi all,

I encounter error message when i try to change the status from Under Development to certified on the Production BOM .

“Max Level in BOM structure on 50 is too high. current Item No. End BOM Header No.XXXXXXXXX. Level 25”

From Item card , replenishment system is Prod. Order.

Regards,

Kelly

Check Prod. BOM No. on the item card, and then the Prod. BOM card. Looks like the BOM defined had Type Prod. BOM on Line and it has gone on loop. The max. level of Prod. BOM is 50 in standard application.

cheers.

I would check what you are doing because it would seem you are putting multi-level BOM’s within multi-level BOM’s - are you sure you should have a BOM in excess of 50 levels? Look in the Inventory Management - Parameters - Bill of Material Tab, there is a maximum number of levels that can be set, but I beleive there is a system restriction of 40 levels to allow elements like Planning the ability to complete. 40 levels is an awful lot - what are you building?

It is performing the check when you are trying to approve the BOM, the only place you could probably see it easily is to go to the BOM designer and expand every level - it depends upon whether you have a BOM within a BOM and therefore creating new levels. If you had a BOM that was originally a top level 0 with components at level 1 and insert it as a sub-bom the level 1’s become level 2 because of where you have inserted it. You have created a scenario where this is greater than 50.

Are you sure you have not created a circularity where you are making item A, and within item A is item B which has as a sub-bom Item A or something like this?

There is a hotfix released for this problem. please check the customer source site for more information

Really? Can you post the link, I would be interested in the change considering the max level is programmed in.
