MAM 2.5 - User View Manager

Question

Hi MI Experts,
I'm having great trouble getting MAM 2.5 to work in our system.
Systems:
Backend: 4.6C
ME: WebAS 6.40, SP14
MI: SP14, patch 4
MAM 2.5 SR3.
I am trying to configure MAM to run for all scenarios.
I've ran the replicator in MEREP_PD for all T01 SyncBOs.
All of them have green lights now.
I've checked table MEREP_207 for MAM_090 and MAM_095 and both have values for my user.
I've followed every single step in the document Synchronization Troubleshooting guide. Yet there is no scenario appearing in my MAM application.
I've triggered the GET_LIST and GET_DETAIL function modules for both SyncBOs MAM_090 and MAM_095 and all have no errors and returned proper values, so I don't believe it is problem with the backend.
I cannot find the mam*.dat files in my Mobile client.
I look at the log in MEREP_MON and for syncbos 090 and 095 there a message: no data to be downloaded.
Any suggestions?
Kind regards,
Michael

OK, believe it or not, I found out what the problem is.
<If uninterested in the reason/investigation and want the fix, scroll to the bottom>
In brief, ABAP bug.
(Our WebAS is a fresh install so does not have any custom development as yet)
When the mobile device synchronizes, the function module
Z_MEREP_GEN_T02_____MAM25_090 (SAP delivered) was called to determine the deltas between the mobile device, the WebAS (ME) and the R/3 backend for processing.
It will need to get data from RDB, the device, and R/3 accordingly in order to do the processing.
The function module first calls function module MEREP_RUNTIME_LOADER to get all the default values of the system, such as RFC destination, scenario properties, mobile group, filters etc.
It looks at table MEREP_203 to get the filters and stores it in structure ldc_sync_generic-WTAB.
It will have the following values.
  FILTER1 = 'ME-SYNC_USER'
Further in the logic of the function module, it calls function module MEREP_RDB_T01_PARTIAL_GET_S (Around Line 1700 <-- talk about modularizing) to get the RDB record stored in MEREP_207.
CALL STACK:
1. Z_MEREP_GEN_T02_____MAM25_090
2. PERFORM rdb_t01_get_non_repl_skey
3. perform init_download_1
      select
        sync_key
        updact
        updts
        r3key
        appending table prt_h_skey
        from merep_207 as l207
        up to ldf_num_of_head rows
        where scenario  = prf_syncbo
          and struct_id = gcf_struct_top
          and updts    <= prs_mass_init-current_dwnlts
          "really neccesaary?
          and (ldf_cond_skey)
          and (prt_wtab) .
In plain english, it will try to look for a record in MEREP_207 with MAM25_090, TOP and filter1 = 'ME-SYNC_USER', and not the actual user of the mobile device! Why? Thanks to the quotation marks.
Of course it will never find anything unless your username is indeed ME-SYNC_USER.
Now, go back to the function module MEREP_RUNTIME_LOADER. It calls the function MEREP_FILTER_GET and function module MEREP_WHERE_CL_CREATE which adds the quotation marks regardless!
<Temporary fix>
My temporary fix is to add ABAP code after the call to the function module MEREP_RUNTIME_LOADER to remove the quotation marks.
  FIELD-SYMBOLS: <fs> type line of merep_twtab .
  LOOP AT ldc_sync_generic-wtab assigning <fs>.
    IF <fs> CS 'ME-SYNC_USER'.
      REPLACE ALL OCCURRENCES OF '''' in <fs> with space.
    ENDIF.
  ENDLOOP.
I will raise an OSS message on this and hopefully get this corrected.
Thanks Kishor for your help to date.
