cobkepmp error

I am working on SCO UNIX version 6.0.0 and MF cobol. The applications is a combination of shell and cobol scripts (running successfully at various other locations) . However, after the application was installed at one location . The following error was displayed for a file location.

Execution error : file '/sbm1/ecs/ecsexe/testdr.int'
error code: 35, pc=1455, call=1, seg=0
35 Attempt to access a file with incorrect permission
---------------------------------------------
Later it was adding cobkeymp error to the above error.
---------------------------------------------

I have checked the owner and permissions for the file. There seems to be no issue with it.
Would be glad if anyone can help.

1. I'm not sure this is the right place for this question. Maybe another mod will move it.

2. Permissions involve having execute access to all directories in the path to the file,
   not just setting permissions on the file itself.

all the directories have the desired executible permissions.
Anyway COBOL installation has been done in root, so would it really be an issue.
