in new AX7 (from LCS), while I was playing around, I found help does not work by default and u got below error.
so to set this, follow below.
login to Dynamics AX7.
then System administration -> Setup -> System parameters -> Help as below
next select the LCS project you are logged into In the "Lifecycle Services help configuration" field, as you might have more than one project on your same LCS account.
then Select the BPM (Business Process Management) libraries (within the selected project) to retrieve task recordings from and display order in which task recordings from the libraries will appear in the Help pane. you can use "Move up" and "Move down" arrow to arrange the libraries.
then save and then you are done.
NOTE: you might have to refresh you browser and reflect the changes.
Thanks,
Yes.Sudhanshu
