Error :BOM phantom structure for xxxxx is higher than 50 levels?

Hi Friends,

I just created a PBOM and assigned version’s for that PBOM.Then i created a PPO and after filling up the Header part i tried to refresh using Function------>Refresh. Then the system throwing an error like…

"BOM phantom structure for xxxxx is higher than 50 levels"

Before creating the versions it was working fine.

Please help me to solve this problem…

thaks in advance

Sounds to me as though you have a circular reference in your PBOM, check the components that are production and these bills making sure it does not contain an item on a higher level.
