I do not have the exact solution for you but i can give you some clues in what direction you can go in order to solve your task.
Firstly "Enterprise PDM increments a version number (1, 2, 3, ...) each time a new version is checked into the vault. A
revision number can then be applied to any version. For example, version 7 of a file may be approved as part of a workflow and receive the Rev1 revision number."
So you can increment a revision number if you assign that in your workflow automatically.
The other thing it seems to me that you need is something to describe what was revised. I think you can use comment for that and all the revisions and comments are preserved in the file history that you can see from in the ePDM vault.
If you need an automated revision description you might want to use a dispatch add-in where you can assign an action on "Change State" event and update the REVNAME variable.
thanks for interest. We use all of you mentioned. I described my need very inaccurately, I´ll try it once again better.
Please, take a look in at the pictures and description below.
if user press TPV button (green rectangle) on checked out document card we obtain revision designation from our ERP. Revision designation is connected with variable ČÍSLO ZMĚNY (REVISION NAME) (in red rectangle). In that time revision number already exist from previous workflow transition. Let´s say we obtain REVISION NAME from EPR as TZ001235 and revision number is 1 and it was done at 07-24-2012.
So now I need to make CURRENT NAME OF REVISION full by REVISION NAME (easy task) and for ERP NAME OF REVISION 1 make it the same but forever, I mean if next revision is need values of ERP NAME OF REVISION 1 and DATE OF REVISION 1 stay displayed as they were and next line is making full by data from EPR and date.
I was wonder if following is possible:
if REVINDEX=1 then ERP NAME OF REVISION 1=CURRENT NAME OF REVISION
(revindex=1; date of revision 1=07-24-2012; current name of revision=TZ001235 => erp name of revision 1=TZ001235)
if REVINDEX=2 and DATE OF REVISION 2>DATE OF REVISION 1 then ERP NAME OF REVISION 2=CURRENT NAME OF REVISION
(revindex=2; date of revision 2=08-25-2012 (date of revision 2>date of revision 1); erp name of revision 1=TZ001235; current name of revision (for example) =TZ004588 => erp name of revision 2=TZ004588)
I´ve tried to use in ERP NAME OF REVISION 1 input formula (picture below) something what could help, but I´am stuck anyway
Does anyone know if there si some tools or another way how to do it in EPDM?
I know dispatch could be helpful, but I don´t want to use dispatch, because this would be too many actions to do for users to acquire precision card data displaying.
Thanks for every note to this subject
