SAP Message Q6059 - Place all key fields at the beginning of the field catalog

Diagnosis
Key field &V1& has a larger field number than data field &V2&.

System Response
Due to the numbering that took place, the system has positioned datafield &V2& before key field &V1&. If you activate an infostructure thatcontains both these fields, then the system will place the key fields atthe front of the generated database table.
This reorganization of the fields is not an error, but often leads toconfusion. For this reason, the system generates this message when youcreate this type of field catalog.

Procedure
The field numbers you assign to the key fields must be lower than thoseyou assign to the data fields.
However, keep in mind that already existing infostructures can becomeinvalid if changing the field numbers affects fields contained in theinfostructure. If infostructures already exist, then do not change anyfield numbers, or make sure you also make the corresponding changes inthe infostructure.
