ECC 6 - New SWWWIDH fields including 'Status'

[Mike Gambier]

Hi all,
 
The official word from SAP on these new SWWWIDH fields will be published as an OSS Note in a few weeks time, so I'm told. As soon as I find anything out I'll pass on the details.
 
I'm still curious as to whether anyone else can find SWWWIDH-STATUS values of '2' in their systems yet?
 
On a slightly different note I've spotted a slight issue with the new Technical Log, specifically the 'Chronological' view, which is trying to select from SWWWIHEAD using a new field called TOP_NODE_ID via a new index SWWWIHEAD~D.
 
In our 4.6c=>ECC 6 test environments the view will just hang (presumably ending in a timeout) because all our 'old' Workflows have a blank value in this field since it was added by the upgrade and not updated during migration or the upgrade process. Interestingly the 'Tree' view works just fine.
 
The code at fault appears to be this Class Method:
CL_SWL_PROCESS_LOG->SELECT_CHRONOLOGIC
...
* new codingIF me->read_from_buffer( ) = ga_true.  ...ELSE.  IF pa_old_logic = ga_true.    ...   ELSE.      SELECT * INTO TABLE at_swwwihead      <======     FROM swwwihead                                 <======     WHERE top_wi_id = pa_swwwihead-wi_id. <======    ...  ENDIF.ENDIF.* end of note 1049570
On the plus side the new TOP_NODE_ID field is a nice top-down link from Parent entries to Children that should do away with a lot of that recursive searching using the 'old' WI_CHKWI field :)

Hello fellow WUGgers, As part of our upgrade testing we've spotted a few new fields on the Workflow Deadlines table SWWWIDH that have crept in without any explanation or warning: 
WI_TIMESTAMP      SWW_TSTAMP  DEC   21    7     Workflow: UTC Time Stamp
TIMESTAMP         TIMESTAMPL  DEC   21    7     UTC Time Stamp in Long Form (YYYYMMDDhhmmssmmmuuun)
RETRY_CNT         SWW_RETCNT  NUMC  2     0     Retries for Work Items with Temporary Errors
ALERT_SEND        SWW_ALTSND  CHAR  1     0     Workflow: Alert Sent
RNDNUMBER         SWF_RNDNUM  NUMC  2     0     Workflow: Random Number
STATUS            SWW_DEASTA  NUMC  2     0     Workflow: Status of SWWWIDH Entry
 The one that caught my eye was the new 'Status' field, which currently has two possible values 1 (Active) and 2 (Error). During some of our test we've noticed the odd '2' value creeping in which seems to mark the deadline for death so that it is completely ignored by the SWWDHEX job. Has anyone got any info on what these new fields are used for? The 'Random Number' field is also a bit curious. I haven't trawled through SAP's ABAP Classes yet to find out what it's for but it strikes me as some kind of load-balancing or performance tweak, possibly for parallel streaming. If anyone knows otherwise can they share their knowledge please? :) Regards, Mike GT
