I receive an error, "An internal error occured while calling 'answerPromptEx' API. (Error: ERR_WIS_302710)", when I click on a document link from a summary report that calls a detail report. I figured out that if I have a date prompt in my underlying BEx, the error is returned. If the BEx does not include a date prompt, then the document link works fine. I can reproduce this issue with two different date fields.
I checked the dates and could not find any oddball values. They were dates from 2011 to 2013. Has anybody experienced this issue? If so, how did you solve it? I've searched the internet, but haven't found any definitive answers.
