Good evening,

This shows how to put a custom label on a SysTableLookup:

public static void lookupSalesId(FormStringControl _ctrl)
{
    SysTableLookup sysTableLookup = 
        SysTableLookup::newParameters(tablenum(SalesTable), _ctrl);
    Query query = new Query();
    ;
  
     query.addDataSource(tablenum(SalesTable));
  
     //'true' is used to specify which field we are returning from the lookup. 
     //By default the first field added is returned, so here 'true' is superfluous. 
     sysTableLookup.addLookupfield(fieldnum(SalesTable, SalesId), true); 
     //Use this setLabel() call right after the adding the field you need to customize
    sysTableLookup.setLabel("My custom SalesId label"); 
     sysTableLookup.addLookupfield(fieldnum(SalesTable, SalesName));
     sysTableLookup.parmQuery(query);
    sysTableLookup.performFormLookup();
}

Normally, you would define this static lookupSalesId() method on the table SalesTable, since it is closely related. Then you could call this method from a form by overriding the lookup() method of a Form's Data Source field as such (logically, a field of the same type as the one you're looking up):

 public void lookup(FormControl _formControl, str _filterStr)
{
     ;
  
     SalesTable::lookupSalesId(formControl);
}
