report function "need()"

[spartacus]

I programmed in a reports after field section a "need()" function call. I retrieved the argument for need from tttxt002.nlin (The number of lines, which the current text needs). I tried also with a fixed number as argument, but that doesn't help. The report crashes sometimes with the message :"Function need; Recursion not possible refcount=2; Can not continue in <reportnp> in DLL: ottstprepdll(get.company).."

Is it possible, that this is a problem of the report DLL?

Thanx

Could it be that it crashes because you have texts with more than 60 lines, meaning that it will never fit on one page?

I think this cannot be the reason. I think I have a maximum about 12 lines

I have never used the need function, but I see from your post that you are checking it in an 'after field' section. Is it in the after.print or before.print section? From a quick glance at my knowledge quest CD it mentioned that you would use this function in the before.print section on a text field. I am not sure if that makes a difference. Just a guess - I really thought Han had solved it.

Hi Mark,

thanks for that hint, but I used it in a "before.print" - section.

Thanks

Can you reproduce the error? If you can I would suggest that you debug the report script, I don't have a clue why it happens. For sure Baan doesn't support recursive calls so you have to find out by debugging what exactly is happening.

Hi Han,

I can not debug, because at the moment I have no access to that system anymore.
Due to a lag of time I programmed the "need()" manually, with spool.pg.length and the actual line number. That works fine.

The report which is concerned is a cust of one of the tisfc0408m000 reports. In the program-script of this session the reporthandling is realized with brp.open, brp.close...... (IMHO a little complicated). Maybe the reason for the problem with
"need()" is related to that.

Hi Spartacus,
I had encountered same Probelm of Recursion not possible for function say "need()" ref count = 2
I think that in Baan Resursion is restricted or not allowed [ i might be wrong to say that ]
but what i did to solve this proble is to have two functions calling each other
ie

|        calling need.one() function from main body 
         need.one()
...
function need.one()
{
    if condition then
         need.two()
    else 
|    Exit through the function
    endif 
}

function need.two()
{
    if condition then
         need.one()
    else 
|    Exit through the function
    endif 
}

Thanks and Regards
Arun

Recursion in Baan is possible, as long as you don't use function arguments and local variables. So in the example above: it is not because you use two functions that makes it possible, it is because you don't have local variables and no function arguments.

Hi , Just Today i had the same problem. It occurs when you have a text field in a footer layout ( in despite you have text fields defined in details layout). you can discover where is the problem , running the report in debugger, entering "c" in the debugger session. Once the program stop pointing the line who caused the problem you can determine ( by the name of the function in generated script), who were the format/s where the text field is placed.

Hope this post can helps you and sorry about my english
