Appraisal Template-Cancel Release

Hi All

Please suggest for the following.....

I created an Appraisal Template in PHAP_CATALOG.

Then I released it & created some Appraisal Documents. Now I want to make some changes in the Template but for that I have to cancel the Release first.

So, I deleted all the Appraisal Documents using PHAP_ADMIN.

But, now when I try to cancel the release system doesnt allow me & throws the following error.....

''The element you have chosen is already being used in an appraisal document or anonymous appraisal.''

Although I have deleted all the Appraisal Documents using PHAP_ADMIN.

Please Suggest

Thanks & Regards
