Hi Venkat,
generally every folder in EasyDMS is a document BOM header in the backend system. So you can create, edit or display "folders" always via the backend transactions CV11, CV12 or CV13.
If you look for some missing folders and you know the description you can use the search transaction CV04N to look for the document info record. As soon as you got the document info record data you can check it in transaction CV03N or CV13. Here you can check if the "deletion flag" or the "document structure" flag is set.
If the deletion flag is set the folder will not be available in the EasyDMS. If you know the superior folder data you can also use transaction CV13 to display all the positions of this document BOM header (folder) to check if the missing document info record is listed here as position.
If you know the document data you can also use database tables like DRAW or DRAP to get more information about the current status of the document.
I hope that this information could be useful for you.
Best regards,
Christoph
