I need to find specific record in PfiWorkunitVariable table. In order to do this I try to use Landmark transaction with following parameters:

_dataArea="lmstglpa" & _module="pfi" & _objectName="PfiWorkunitVariable" & _actionName="Find" & _actionOperator="NONE" & _actionType="MultipleRecordQuery" & _pageSize="30" & _filterString="VariableValue = \"0010003781\"" & UniqueID

With hard-coded value it works well but as soon as i tried to use variable it stop working. Variable is like '<'!vOrderExists'>' - without quotes, because site do not accept everything inside  '<'! and '>'
This is example how it looks with variable and error I receive:
_dataArea="lmstglpa" & _module="pfi" & _objectName="PfiWorkunitVariable" & _actionName="Find" & _actionOperator="NONE" & _actionType="MultipleRecordQuery" & _pageSize="30" & _filterString="VariableValue = \"vOrderExists<!--vOrderExists-->\"" & UniqueID

  Variables in Process:
vTest =
vOrderExists = 10003781

Activity completed: Start

Activity started: LMTxn5190  (Run Id: 18)

Any idea what I'm doing wrong?

Hi Taras - I was able to make this work correctly in LMRK v9.2.5 using the variable in the filter using the standard variable naming, but they key is that I had to also include the PfiWorkunit and PfiWorkunitVariable fields in the output - without those, it doesn't work correctly.  I'm not sure why IPA requires this, but it does. 

Attached is a screenshot of my landmark node that worked correctly:



By the way, filtering can be VERY SLOW.  If you can limit by the PfiWorkunit and PfiWorkunitVariable in the query you will be better off.  However, that may not be possible in this case. 

Be cautious, however, because they way your query is currently written, there is no way to confirm that the record you are getting in return is what you are really looking for - it could be from any workunit and any variable name that happens to have a value of "10003781".

Good Luck!   Kelly

Hi,
First of all many thanks for your help.

I tried to use your example but problem still exist.
This is example from my Landmark Transaction node

In attached file I added execution log.

Situation is following. When I use hardcoded value in filter everything works perfect, but as soon as I tried to use variable i receive error  "Content is not allowed in prolog"

You have too many quotes around your filterString parameter.

Even without quotes, around filter String parameter, result is the same.
Will need to open Infor ticket.

Found the reason of situation described above.
Lawson consultants installed different versions of Rich Cliend (10.0.3.11.5675) and Process Designer (10.0.3.0.5533) which cause such issue. After versions synchronized all issues gone.
