Exception CX_SY_NO_HANDLER (type CX_SY_DYN_CALL_ILLEGAL_TYPE)

I have this particular error since the last Thursday and I could not find any solution, so I ask you guys if you know hot to fix it...

First:

I generate a CLASS (SE24) for download a pdf with a spool number.
Before that CLASS I generate a method to convert OTF -> PDF,

• In the parameters of the METHOD I declare 'I_IS_OTF' type C (IMPORTING) for check if OTF is 'X'
• 'I_SPOOL_ID' type I (IMPORTING) for write the SPOOL ID to transform
• And the problem comes here, I declare 'TABLE_BIN' type TABLE (EXPORTING) and 'SIZE_PDF' type I (EXPORTING).

The TABLE_BIN give me the 'Exception CX_SY_NO_HANDLER' and then explotes, but still read the SPOOL and give me information. I'm base in this code -> 'RSTXPDFT4'

I don't have a program to run the methods, I just use the same class.

THE CODE:

    CONSTANTS c_pdfcnv_pdfdst_xstring(1) TYPE c VALUE 'X'.

DATA: numbytes TYPE i,
      jobname  TYPE tbtcjob-jobname,
      jobcount TYPE tbtcjob-jobcount,

      pdf_stream_tab TYPE STANDARD TABLE OF rspolpbi,
      pdfspoolid   TYPE tsp01-rqident.

 IF i_is_otf = 'X'.

  table_bin  = pdf_stream_tab.
  size_pdf = numbytes.

I already debugging this a few times, I only find the SY_TABIX give me '2'.

I tried using a try & catch, but still with the same error. 'Exception CX_SY_NO_HANDLER'.

In the information you have given, you have used:

1. the type SETST_TYPE_TABLE for passing data to the parameter table_bin, which is a table of lines of type 70 characters,
2. and you tried to initialize it with the variable pdf_stream_tab which is a table of structured lines of type RSPOLPBI which is a DDIC Structure with 1 component of type 128 bytes.

As explained in the documentation below (I just indicate what is relevant to your case), this is not permitted, because the line types of the 2 tables are not convertible (the line types are respectively a field which is character-like and a structure which is not character-like).

Instead, as a PDF is made of bytes, not characters, you should always use variables "byte-like".

NB:

1. ABAP Documentation - Assignment and Conversion Rules
   • Conversion Rules for Internal Tables
     > "Internal tables can be assigned to each other if their line types are compatible or convertible"
   • Conversion Rules for Structures
     • Conversion between flat structures and single fields
       > "If a structure is purely character-like, ..."
       >
       > "If the structure is not completely character-like, the single field must have the type c and the structure must begin with a character-like fragment ..."
       >
       > "No conversion rule is defined for any other cases, and assignments are not possible."
2. Here are the definitions of the above types
   • SETST_TYPE_TABLE in the type group SETST (transaction code SE11 for instance):
     
   • Structure RSPOLPBI in SE11
