Please check the employee regulations and those relating to disciplinary proceedings. It's quite clear when and for what reasons warnings can be given and the different categories and levels.
I would assume yours is classified as a 'capability' warning? It doesn't effect profit share but it may be worth appealing depending on the level they've given you. Ie, final. If it's just a written warning, you would not be able to appeal but a final warning would require a previous misdemeanour.
How sad that we have to be discussing issues like this on a public forum. EK management....take note!
