Not able to check in a document

Hi,

We have created two users. For example A & B. User A has all access and user B has only Document Maintainenace authroizations (zsap_plmwui_dms_maintain).

First step: i have logged in as user A and created a document and was able to check in a file.

Second Step: i have logged in as user B and created a document but not able to check in a file.

Note : The file i am trying to upload &b doc type is same for both the users. But for the user B i am getting an error as "Error Uploading".

Error details:

Message no. 26128

You want to upload a file under path C:\Users\xxxxx\Desktop\test.docx. This is not possible. Perhaps the file does not exist.

Check the access path for the file

Could anyone please help me on this,

Thanks in advance
