Content

After creation of disclosure master document we are unable to manage the individual doclets added to the master document. We have multiple issues-
1) we are unable to open a certain doclet which says file formatted not supported especially when trying to open xlsx format.
2) At times when trying to access a doclet, it throws an error repository item unavailable and it gives error" Need to migrate the doclet".
3) Once a disclosure master document is created and doclets are added during the first instance, we are unable to manage the doclets there after.
