You CAN rename various ''modules'' in QC.
This is an ''all or nothing'' change for the new ''title''.

Please be careful as it may have strange results - namely utter confusion from long time QC users.
Also, there are some ''hard coded'' occurrences of ''Cycle'' (in your case) that you cannot change.

I just tried this value for **REPLACE_TITLE** (i had to add it to my site parameters list):
cycle;iteration;cycles;iterations

I worked, mostly. I had a few places where it still said ''cycle''.
TEST this FIRST on a TEST instance of QC.

Here are the formal directions:

Generally, an admin can rename any ALM module for all projects by adding the **''REPLACE_TITLE''** parameter in the Site Configuration tab.

Syntax for the value is (without quotes):

*''original title [singular];new title [singular];original title [plural];new title [plural]''*

Limitations for this method:

1) It cannot recognize non English characters as parameter value.

2) The Parameter will affect all projects.

I you wish to go into the DATACONST table for a given project, you can actually make a ''title'' change for one project at a time.

Use the same parameter name and value syntax as above.

Example (go into tables for your project, then:

*INSERT INTO DATACONST VALUES ('REPLACE_TITLE', 'Cycle;Iteration;Cycles;Iterations')*

Be careful, this will occur for one project at a time and will NOT show up in the Site Parameters tab in site admin -- it may be confusing later if you change admins and they wonder how one project behaves differently than the others. Document this modification for future admins and(and you possible forgetfulness).
