When you scroll any list in the classic client in Microsoft Dynamics NAV 2009, you experience bad performance. This problem occurs if there are many entries in the Record Link table. However, when you try to create a required index for the Record ID field, the Type field and the Company field, you receive the following error message:
The fields in an active key cannot exceed 252 bytes. The size of the Record ID,Type,Company key fields in the Record Link table is 258 bytes.
This problem occurs in the following products:
Microsoft Dynamics NAV 2009 R2
Microsoft Dynamics NAV 2009 Service Pack 1 (SP1)
This problem occurs because there is no index for the Record ID field, the Type field and the Company field.
