The manual clearly states that there is a Common Services level requirement:

"Important! Ensure that the required CA Common Services products are installed and maintained at genlevel that is indicated on the product cover letter. For information about installing CA Common Services, see CA Common Services for z/OS."

"Before you install CA File Master Plus, CA File Master Plus for IMS, CA File Master Plus for DB2 for z/OS, we strongly recommend that you install CA Common Services for z/OS Release 14.1. Quality Assurance is certified with this release."

This leads me to believe there is no File Master requirement for CA Common Services. Is that correct?

CCS release 14.1 is clearly stated as a requirement:


There are no changes to the cover letter.
