CAS9180E license key error for product 4A after install of PTF LU14059

Products

Gen

Issue/Introduction

After installing Gen 8.6 CARS update 2408 which contains just PTF LU14059 see this error reported in CICS region when Gen CICS applications are executed:
CAS9180E - CPU ... Requires a LMP key to run Prod (4A) GEN-ENC-CICS-Opt

Currently using z/OS Implementation Toolset (product 4E).
We don't use a Gen Host Encyclopedia and we don't have or need a license for product 4A which according to LMPTableMASTERFILE.pdf (LMP Product Code Listing) is "Gen Encyclopedia Construction Environment Option for CICS".

Environment

Gen CICS applications

Cause

The Gen CICS runtime license used to be checked in Host Encyclopedia Construction but that was an incorrect place for the check. The new PTF LU14059 corrected the check to take place at runtime itself. See doc page Gen Licensing:
*****
z/OS CICS Runtime SCRT Update
After applying this PTF LU14059, usage of Gen CICS Runtime is reported on the SCRT report. There is one check that is done once per day for the CICS region wherever Gen applications are executed. Since the LMP code 4A is removed from Construction in PTF LU13160, now it is reported for CICS runtime usage. If Common Components and Services PTF LU13705 is also applied, the correct product name is reflected in the SCRT report.
*****

The key 4A is also now renamed to be "Gen Runtime for CICS" (visible in the SCRT report and SYSVIEW) and the above LMPTableMASTERFILE.pdf has been updated (both for CICS and IMS runtime options).

If related Common Components and Services PTF LU13705 is also installed the message would contain the updated product name: GEN-RT-CICS-Opt

Resolution

If Site ID does not currently have a 4A key then it needs to be obtained from the Broadcom Customer Care team via creating a support case in the Support Portal "My Cases" section. Use Issue Type = "Non-Technical" and Product = "CA Licensing".
With the new Gen SKU bundle licensing the Mainframe bundle includes SKU "Gen Encyclopedia Construction Environment Option for CICS" (GENHCU002), so all Gen Mainframe licensed Site IDs should automatically have entitlement to the 4A key irrespective of whether they use Host Encyclopedia Construction or z/OS Implementation Toolset. If encounter any issue in obtaining that key please contact your Broadcom Account team.
For any LPARs running Gen CICS applications, where the Gen CICS runtimes have been updated by LU14059, the 4A key also needs to be added there for the runtime license check to be validated.

Additional Information

A similar error could occur for product key 4C for IMS (now "Gen Runtime for IMS" instead of "Gen Encyclopedia Construction Environment Option for IMS") after installing PTF LU14829 e.g.

CAS9180E - CPU ... Requires a LMP key to run Prod (4C) GEN-ENC-IMS-Opt (Common Components and Services PTF LU13705 not applied)
OR:
CAS9180E - CPU ... Requires a LMP key to run Prod (4A) GEN-RT-IMS-Opt (Common Components and Services PTF LU13705 applied)

Please see doc page Gen Licensing:
*****
z/OS IMS Runtime SCRT Update
After applying PTF LU14829, usage of Gen IMS Runtime is reported on the SCRT report. There is one check
that is done once per day in each IMS MPP region wherever Gen applications are executed. Since
the LMP code 4C is removed from Construction in PTF LU13160, it is now reported for IMS runtime usage.
If Common Components and Services PTF LU13705 is also applied, the correct product name is reflected
in the SCRT report.
