You are getting the below issue while trying to import a transport from STMS.
Solution
As per SAP Note 2497053 – STMS: Adjust the queue – Source file could not be opened,
- Make sure the transport request files (cofile and data file) exists in the transport directory (DIR_TRANS) of the source system and they have the correct authorizations.
- If for some reason the transport request files were deleted and the request is still in the transport queue, then the request can be deleted:
- Select the request in the transport queue
- Menu Request
- Delete
