Dimension Problem

Dear concern
I m using Navision 4.0 SP3 in SQL.I have many companies in my Database.In only 1 company I have given problem:-

I set 2 Global dimensions in G/L Setup.We have dimension values for both Global dimensions.Global Dimension No. field for Global Dimension code2 becomes zero after some.Then for this I have to update GD2 with same Dimension, then Global Dimension No. 2 comes in Dimension Value table.Then after some time it value in Global Dimension No. field becomes zero for Global Dimension Code2 only.Global Dimension Code1 is always right.Only problem with Global Dimension Code2.
