AX (Global Accounting Engine) creates journal entries only when the accounted amount is not equal to Zero.

As AX summarizes the journal entries by Plan Name (Accounting Class), Code Combination Id, Third Pary Id and Sub Id, if the accounted amount becomes zero, in those cases AX won't create Journal Entries.

Hope you haven't selected Report parameter as "No Report".

Create Accounting has mainly two templates.

"Subledger Accounting Program Report - Standard" inturn calls "Subledger Accounting Program Report - Sub Template".
"Subledger Accounting Program Report - Sub Template" is a sub template and shouldn't be used directly while submiting the Create Accounting.

If the output is blank, the template needs to be crosschecked, which is available in the Options Button of the SRS window.

For Packages:

   SELECT text
   FROM   all_source
   WHERE  name = Upper('&package_name')
   AND line = 2;

   SELECT af.subdir, 
          af.filename, 
          afv.version 
   FROM   ad_files af, 
          ad_file_versions afv 
   WHERE  af.file_id = afv.file_id 
   AND af.filename = '&file_name'
   ORDER BY afv.creation_date DESC;

Are you using MO view like ap_invoices?
  For all org_ids' data      -> Use ap_invoices_all
  For specific org_id's data -> 11i -> dbms_application_info.set_client_info(&org_id);
                                R12 -> mo_global.set_policy_context('S',&org_id);

gl_je_lines (je_header_id, je_line_num)                -> gl_import_references (je_header_id, je_line_num)

gl_import_references (gl_sl_link_table, gl_sl_link_id) -> xla_ae_lines (gl_sl_link_table, gl_sl_link_id)

xla_ae_lines (applicaiton_id, ae_header_id)            -> xla_ae_headers (application_id, ae_header_id)

xla_ae_headers (application_id, event_id)              -> xla_events (application_id, event_id)

xla_events (application_id, entity_id)                 -> xla.xla_transaction_entities (application_id, entity_id)

Create Accounting (with Transfer to GL parameter as Yes) will transfer only the journal entries to GL, which have been created by the same Create Accounting run.
To transfer the journal entries to GL, which have been accounted by previous Create Accounting (with Transfer to GL parameter as No) runs, "Transfer Journal Entries to GL" concurrent program needs to be run.

Online Accounting: (For single entity / transaction)

Only few subledgers are providing this feature.

Draft will create journal entries, which are not final, which means they are not ready to be transferred to GL.
You can see the accounting in xla_ae_headers and xla_ae_lines.
