Is there a BAdI for Talent Management. Within the Talent Profile (MSS->Employee Performance & Development->Talent information-> Talent Profile) I want to change the color scheming for performance and scale.
Now here's a question I've never seen asked before on SDN! Excellent question. I've actually been asked about this by clients more than a couple times. Eventually everyone has stuck with the SAP delivered color schemes, but the topic definitely comes up.
I'm not suggesting the way we were going to change the colors is the only way (or even the best way), but here's one option for you.
If you go to SE80 and select mime repository, you'll navigate to SAP -> PUBLIC -> BC -> UR -> nw5 -> themes -> sap_tradeshow (or whatever theme you're using) -> common -> thresholdslider.
Now you'll see a bunch of different .gif files. Theoretically you can download and upload here. So you have all the gif files here. You could create your new gif that's identical, but with the same colors and put it in here. As a warning, don't expect all the filenames to make sense to what rating they actually represent.
For a broader warning, one thing I caution people about is how SAP uses those color schemes in a few different places you've gotta keep track of each you're using and it may not be worth it for just the color schemes. Additionally, if you're using the Predefined Performance Management process, the appraisal overview tab of the review uses the color schemes as well, but they're part of the actual Flash .swf file. Changing these colors here won't help that. I don't know of anything short of changing the .swf file that will accomplish adjusting colors in the PMP final rating function.
Hope that helps and good luck!
ps - out of curiosity is the issue you're trying to work around that your customer doesn't think it's right that a person rated 3 out of 5 should be colored yellow?
