From GOS attachment to generate spool or pdf

[former_member756406]

Hello All,

Requirement Details:

User can attach any kind of document to FB03 manually from presentation server(GOS ATTACHMENT). I have to generate pdf / spool for that attachment. I have used binary_to_xstring then call fm otf_to_pdf. But the table binary_tab when I pass to otf_to_pdf, that m getting otf command '//' endpoint missing.Please help on this. Thanks in advance..

The issue is conceptual rather than technical.

OTF_TO_PDF can only convert OTF data (output generated by SAPscript / SmartForms / SAP Spool).
A GOS attachment is not OTF, it is already a stored binary document (PDF, DOCX, XLS, JPG, etc.).

That is why you get the error “OTF command ‘//’ endpoint missing” — you are passing non‑OTF binary data to OTF_TO_PDF.

Important clarification

• GOS attachments uploaded from presentation server are stored via ArchiveLink / Content Server

• They are not spool requests

• OTF_TO_PDF must not be used for generic attachments

What you should do instead

Case 1: Attachment is already a PDF

• Retrieve it using:

  • ARCHIVOBJECT_GET_TABLE or

  • SO_DOCUMENT_READ_API1

• Convert SOLIX → XSTRING

• Directly:

  • Download it

  • Display it

  • Attach it to email
    ✅ No conversion required

Case 2: You need a Spool
You cannot create a spool from an arbitrary attachment unless:

• The attachment was originally generated by SAP (SmartForm / SAPscript)

Spool creation is only possible from:

• SmartForm

• SAPscript

• Adobe Form

• ABAP list output

Case 3: Attachment is DOC / XLS / IMG
SAP does not provide any standard FM to convert these to PDF.
Options:

• Use an external converter (OpenText, Adobe, PDFLib, etc.)

• Or store/display the original file as-is

Summary

• OTF_TO_PDF ❌ cannot be used for GOS attachments

• GOS attachments ≠ Spool output

• If already PDF → just retrieve and display/download

• Conversion to PDF requires external tools unless SAP-generated output

Hope this clarifies the limitation and correct approach.
