Hello experts!! NAV2018

I need to print the value of the work description field in sales header, for what I did this code where TextoStreamin(Text,1024):

"Sales Invoice Header".CALCFIELDS("Work Description");
IF "Sales Invoice Header"."Work Description".HASVALUE THEN BEGIN
"Sales Invoice Header"."Work Description".CREATEINSTREAM(Streamin,TEXTENCODING::Windows);
Streamin.READ(TextoStreamin);

but when the value exceeds 1024 characters is cut, I replaced the text variable with a bigtext like this, where btWorkDescription(bigtext)

CLEAR(btWorkDescription);
"Sales Invoice Header".CALCFIELDS("Work Description");
IF "Sales Invoice Header"."Work Description".HASVALUE THEN BEGIN
"Sales Invoice Header"."Work Description".CREATEINSTREAM(Streamin,TEXTENCODING::Windows);
Streamin.READ(btWorkDescription);

but it gives an error


please help me and thanks!!

    You do not need BigText.
    "Sales Invoice Header".CALCFIELDS("Work Description");
TempBLOB.BLOB := "Sales Invoice Header"."Work Description";
WorkDescriptionText := TempBLOB.ReadAsText('', TEXTENCODING::Windows);
//or if your WorkDescriptionText is declared as text with some lenght:
WorkDescriptionText := COPYSTR(
  TempBLOB.ReadAsText('', TEXTENCODING::Windows);
  1, MAXSTRLEN(WorkDescriptionText) );

    What kind of variable is TempBLOB ?
    Blob type variables can not be defined in the report

    Apart from the screenshot from Report 206, which is somewhat irrelevant here - you are not supposed to pass a BLOB field, but the text extracted from it.

    Slawek_Guzek, your code works but does not respect paragraph breaks; this is the result with your code:

    and what I need is:

    but that works with more than 1024 characters.
