Auto-populate a Revision History table

We looked into this. It can't be done currently. I opened an idea for it here:

https://community.ptc.com/t5/Windchill-Ideas/Add-Windchill-parameters-for-latest-change-number-and-where-used/idi-p/470362

Ultimately though I convinced the organization to eliminate the revision block entirely and instead now we just have a statement where it used to be that says something like revision table is available upon request in Windchill.

It can be easily done using parameters and some relations to create a shift register.

I assume PTC_WM_REVISION, PTC_WM_MODIFIED_BY, PTC_WM_MODIFIED_ON are environment parameters coming from WC.

Create the following parameters (string type) to trace the last 3 revs and shift them when a new rev occurs

RV_REVL_INDEX

RV_REVL_DESIGNER

RV_REVL_DATE

TEXT_CURRENT_REV

RV_REVS_INDEX

RV_REVS_DESIGNER

RV_REVS_DATE

RV_REVS_TEXT

RV_REVT_INDEX

RV_REVT_DESIGNER

RV_REVT_DATE

RV_REVT_TEXT

Where REVL, S, T stand for Last, Second-last, Third-last.

RV_REVL_INDEX must be set as default in your template to "00" or the default text corresponding to the text of your base revision.

Then add the following relations in your part/assembly:

IF RV_REVL_INDEX != PTC_WM_REVISION

/* begin shift register */

RV_REVT_INDEX = RV_REVS_INDEX

RV_REVS_INDEX = RV_REVL_INDEX

RV_REVL_INDEX = PTC_WM_REVISION

RV_REVT_DESIGNER = RV_REVS_DESIGNER

RV_REVS_DESIGNER = RV_REVL_DESIGNER

RV_REVL_DESIGNER = PTC_WM_MODIFIED_BY

RV_REVT_DATE = RV_REVS_DATE

RV_REVS_DATE = RV_REVL_DATE

RV_REVL_DATE = PTC_WM_MODIFIED_ON

RV_REVT_TEXT = RV_REVS_TEXT

RV_REVS_TEXT = TEXT_CURRENT_REV

ENDIF

In case of a new revision just write in TEXT_CURRENT_REV the description of the current revision.

Create a table or a note in your drawing writing your preferred parameters order.

I used the following where the last rev comes always to the top of the list.

RV_REVL_INDEX   RV_REVL_DESIGNER   RV_REVL_DATE   TEXT_CURRENT_REV

RV_REVS_INDEX   RV_REVS_DESIGNER   RV_REVS_DATE   RV_REVS_TEXT

RV_REVT_INDEX   RV_REVT_DESIGNER   RV_REVT_DATE   RV_REVT_TEXT

This is just an example, you can customize it as you want.

In case you want to trace 4 or 5 revs the trick is the same. Just add 1 or 2 new sets of parameters (4th to last, 5th to last) and add them in the relations of the shift register. You use the revision text coming from WC, just identify the corresponding parameter and include it in the shift register instead of TEXT_CURRENT_REV. I used this method in many PDM/PLMs. It always works well.

Creo seems not to have built-in functionality for maintaining such revision history tables.
I can not recommend the releation-driven approach: you have to fiddle around with parameters in releation code. Disadvantage: write and maintain such code within each models/drawings.

What works much better is a seperate TOOLKIT application that examines the model/drawing right after retrieval and/or before save to check for changes, manage a rolling table, etc..

(We, PDSVISION offer such a tool, but encourage to maintain revision meta data not in parameters/drawing tables but in Windchill.)
