Empty Fields in Array

Posted on Nov 02, 2019 at 07:17 PM 102 Views

Hello,

I have a question. I am trying to get just a single field in my array. But I am always getting an empty entry towards my target field. How does that come? And more important, can I remove that somehow?

Thanks for any reply.

Kind regards

Sam

WhileReadingRecords;
global stringvar array art;
global numbervar artcounter = 0;

if ({@le_Artikel_Nummer} = "SA11524") Then
    (artcounter := artcounter + 1;

    (redim art[artcounter];
    art[artcounter] := {@le_Artikel_Nummer}));

    Hi Samuel,

    Try:

    WhileReadingRecords;
global stringvar array art;
global numbervar artcounter = 0;
if ({@le_Artikel_Nummer} = "SA11524") Then
    (
     artcounter := artcounter + 1;
     redim preserve art[artcounter];
     art[artcounter] := {@le_Artikel_Nummer};
    );

    Hi Abhilash,

    I have tested your code but I get the same result. I put a picture to show what it looks like (@_Artikel) and the complete Table (AUFDRUP_TXT.ARTNUM). Does a way exist to get just there entry? I made a count on it and get 1 in return...so does the problem maybe lies somewhere else?

    Jeah i put it in the header and a second reference in the detail section. worked out for me. thanks a lot. Bytheway i changed the type to numbervar because i needed an other field but tried to get the articlenumber first.

    whileprintingrecords;
global numbervar array art1;
if count(art1) = 0 then "" else cstr(maximum(art1), 0, "")
