Travel Expense Statement - Page Number always 0

Hi:

Since our upgrade from R4.6C to ECC6.0 we find that the travel expense statement always displays as zero ("0") no matter how many pages are in the statement.

Any ideas on how to fix this or the cause?

I have verified that the configuration for the Form Header Layout is the same in the old system and new. We use the standard form FOXX for this.

Thanks

Lisa
