Suppress Blank lines in report

in the data item properties is the PrintOnlyIfDetail set to Yes?

i'm not sure if that will help with the footers but worth a shot - unless someone knows for sure?

I recall somewhere that Navision always leaves space for a section, whether it actually prints the text or not. A solution I know of involves creating a dataitem for each section (or at least a dataitem that covers all the footers, in your case).

So, suppose your report has a Customer dataitem, with the following footer sections:

Customer - Footer 1
  CurrReport.SHOWOUTPUT(Condition1);

Customer - Footer 2
  CurrReport.SHOWOUTPUT(Condition2);

Customer - Footer 3
  CurrReport.SHOWOUTPUT(Condition3);

My solution is to create three new Integer dataitems, with DataItemTableView set to SORTING(Number) WHERE(Number=CONST(1)).

Customer
CF1 - Integer
CF2 - Integer
CF3 - Integer

Note that the sections are not indented under Customer, so they will be triggered only after all the Customer records have been processed.
Now in CF1 (and similarly for CF2, CF3) put the code

IF NOT Condition1 THEN
  CurrReport.SKIP;

(you might have to use BREAK instead of SKIP).

There is a second alternative. It is not so useful if the footers have lots of controls, but suppose they just contain a label "This is Footer 1", "This is Footer 2", "This is Footer 3". Then the three footers could be replaced by a single footer with a textbox (instead of label) with SourceExpr = MyFooterTxt; you would then have the following code:
[code]
CASE TRUE OF
Condition1: MyFooterTxt:= "This is Footer 1";
Condition2: MyFooterTxt:= "This is Footer 2";
Condition3: MyFooterTxt:= "This is Footer 3";
END;
[\code]

I hope this is clear enough.
