Message text: LGPS: Wage Type Group &1 contains no Wage Types (Table T52D7)
You have activated the payroll function GBLGP but have not customized
this wage type group to contain any wage types.
This is a warning message only. It may be correct that this wage type
group is empty.
If it is not correct that this wage type group should be empty then add
the relevant wage types to this wage type group.
If it is correct that this wage type group should be empty then you have
two choices;
1)     Ignore this warning.
2)     Add a wage type to this wage type group that is not used in your
payroll implementation. (i.e. /N31 has not been used since the NI
re-write, but still exists for historical payroll results to be read
correctly.)
