usage / dependencies in data services

Hi experts,

We are experiencing some problems with dependencies in data services.

usage says 0 althoug a Dataflow is used, or maybe a workflow says that is used 17 times when only is used once. I coulnd't find how to replicate it, it just happend randomly.

a) close and enter in the Application does not resolve this

b) refresh object library does not resolve the usage column

b) there are differents ways to fix it depends of the case,

   17 times used : when use "where used" function it shows the proper value

     0 times used object: I had to delete the object and add it again in the parent object.

0 times used object is the matter that scary me a lot, because when try to export ATL file, the object is not proposed.

the version used is SAP BO DS 4.2 SP6, and the only sap note that seems to describe a similar issue, does not match my version

  2314782 - The Usage column for a table in a Datastore shows 1 when it should be 0 in SAP Data Services

All help provided will be apreciated.

thanks in advance
