SAP Cloud ALM vs CHARM in managing one landscape with maintenance & evolution projects

[Maurizio_Manera]

Hi,
for a landscape S4 Hana Rise I would like to start with SAP Cloud ALM for Change & Deployment Scenario.

With Solution Manager CHARM there is the CSOL functionality that ensures that when an object is changed in a managed system, it is locked in the SAP Solution Manager system. Depending on the conflict scenario, this prevents multiple edits of the same object in different transport requests or projects at the same time. This applies to all managed systems and clients for which the cross-system lock is active.
This allow maintenance line and evolution line to be under control.

I've read that CSOL functionality for SAP CALM will be available but only for detect whether development objects have been touched in different system landscapes; this is not my case because I have only one S4 Hana Landscape.

So if I decide to use CALM how can I manage conflict between evolution line and maintenance line if CSOL it's not released for this purpose?

Which are the best practices to follow for managing evolution and maintenance line with features to replicate similar functionality?

Regards
Maurizio

Hello Maurizio, 

Sorry for not answering in the blog.

As you can read in SAP Road Map Explorer https://roadmaps.sap.com/board?PRODUCT=73554900100800002513&range=CURRENT-LAST#Q2%202025

CSOL is planned for Q4 2025, and after CSOL Retrofit will arrive also planned for Q4 2025:

"Cross-system object lock foundation for retrofit

Overview

• Object locks across systems to detect whether development objects have been touched in different system landscapes
• The locking mechanism should build the foundation for an automatic retrofit option

Benefits

Enable consistent deployment orchestration across supported transport tools. "

"Support for the automatic retrofit

Overview

• Support the automatic retrofit process based on a cross-system object lock mechanism
• Define the source and retrofit system to use SAP Cloud ALM for automating the retrofit process
• Allow only transport objects without any conflicts to be retrofitted automatically
• Do not provide support for a semi-automatic retrofit

Benefits

Accelerate implementation projects and reduce manual integration and configuration efforts by leveraging the suite quality “coordinated lifecycle management” for harmonized software provisioning, setup, and operations, as well as monitoring solutions, for your intelligent, sustainable enterprise"

Best regards,

Dolores

Hi Dolores,

I know that there will be a new functionality for CSOL but it seems will work only with two separate Development system.
With CHARM it is possible to raise a warning or error with CSOL also if you use only one development system as reported in the help online.

https://help.sap.com/docs/SAP_Solution_Manager/8b923a2175be4939816f0981b73856c7/5e0500dc-b19f-4f5a-9... 

"Regardless of whether you use a separate development system or share the same system for your projects, you must avoid different teams working on the same object concurrently if the changes are to be imported in the same production system. It can lead to inconsistencies. The object must stay locked until it has been imported in the production system."

Will this function be available in CALM with CSOL ?

Which are the best practices to replicate the same function?

Maurizio
