Introduction of application specific Extended Warehouse Management Checks in SAP EarlyWatch Alert
SAP EarlyWatch Alert is an automated service analyzing the essential administrative areas of SAP Systems. Alerts indicate critical situations and give solutions to improve performance and stability.
Beginning of March 2021 , based on a collaboration with SAP Mission Control Center and SAP Extended Warehouse Management experts, SAP EarlyWatch Alert tool also provides application specific checks for SAP Extended Warehouse Management (EWM). They can be viewed in the SAP EarlyWatch Alert Solution Finder by selecting the Category -> Application → Extended Warehouse Management .
The EWM (Extended Warehouse Management) Specific checks are introduced as part of the ST-SER release 720 with the aim to fulfill the following aspects:
- Proactive update to Customers on issues and recommendations to prevent issues
- Customers can react to issues such as bottlenecks before they become critical
- Minimize risk of critical down time
- Minimize risk of critical data consistency issues
- Providing information about critical fixes and service packages required for safe system operations
- Ensuring System Performance and Product Stability
Checks which are already released to the customers are as follows:
- LIME Inconsistency check – Released in calendar week 10, 2021
- System Parameters check for Enqueue Server – Released in calendar week 17, 2021
- Capacity Update check for Non-final Storage Types – Released in calendar week 17, 2021
- Failed and Unprocessed Queues in SMQ1 and SMQ2 (older than 2 weeks) – Released in calendar week 17, 2021
- Failed and Unprocessed PPF Actions in EWM (older than 2 weeks) – Released in calendar week 24, 2021
- Update Termination due to missing Handling Units in TU – Released in calendar week 24, 2021
LIME Inconsistency Check
This check triggers an alert to customers who are at the risk of having inconsistencies due to overload on the Enqueue Server. The overload is a consequence of SAP Note 2582237.The SAP Note itself is delivered as part of the Support Pack upgrade or can be manually downloaded by the customer.
To prevent these inconsistencies on the Lime Table, implementation of the SAP Note 2857030 is needed.
Customers will have a decisive red alert in their EarlyWatch Alert report for this check in the chapter for Extended Warehouse Management.
Systems Parameter check for Enqueue Server
The check is introduced to alert customers by pro-actively checking their values set for parameters enque/table_size, enque/snapshot_pck_size and enque/snapshot_pck_ids for the ASCS instance profile of the Enqueue Server.
If the values are not as per the recommendation in the SAP Note 3061137 (enque/snapshot_pck_size * enque/snapshot_pck_ids / 1024 >= enque/table_size), this leads to an overhead on the Enqueue Server and caused inconsistencies in the EWM System.
Customers will have red alert and the corresponding details in their SAP EarlyWatch Alert report for this check.
Capacity Update check for Non-final Storage Types
‘No capacity update check for Non-final storage types’ is introduced to alert with ‘YELLOW’ rating to customers who have non-final storage types without the flag ‘No Capacity update’ with the recommendation of SAP Note 1510229.
After evaluating the relevance of the flag for the non-final storage types and the business process impact, the customers can set the flag for “No Capacity Update” for the non-final storage types, thereby preventing unnecessary DB locks.
Failed and Unprocessed Queues in SMQ1 and SMQ2 (older than 2 weeks)
Due to lack of timely monitoring, customers only realize that there is a hanging queue when a delivery completion or a TU completion cannot be done. At this point, this issue becomes business critical.
This check is introduced to alert the Customers with a ‘RED’ rating in case of failed queues in SMQ1 and SMQ2 older than 2 weeks. An alert with ‘YELLOW’ rating is triggered in case of unprocessed queues in SMQ1 and SMQ2 older than 2 weeks.
This way, customers are made aware of the hanging queues pro-actively and they can act before it becomes critical.
Failed and Unprocessed PPF Actions in EWM (older than 2 weeks)
Unprocessed PPF actions which are scheduled but never executed and long running PPF actions are one of the key contributors in degrading the system performance.
On the other hand, failed PPF actions in EWM can have a serious business impact as they can prevent certain follow up actions and failure of communications which are dependent on the execution of the PPF actions.
Therefore, it becomes necessary that customer is aware of this well in advance to mitigate and fix such issues. Reference SAP Note 1423066, bullet point “Deactivation of PPF action definitions that are not used”.
The EarlyWatch Alert check is introduced to alert the Customer with a ‘RED’ rating in case on failed PPF actions and a ‘YELLOW’ rating in case of unprocessed PPF actions. Currently the first 50 entries for each of the entries is retrieved in the online collector and displayed on the EWA Report.
Update Termination due to missing Handling Units in TU
This Check is introduced to alert the Customer with a ‘YELLOW’ rating in case the below conditions are fulfilled:
- Customer uses yard management functionality and
- Customer has implemented the SAP Note 2940387 and
- Customer has not implemented the SAP Note 3008216
This way, customers are made aware of the SAP Note 3008216 which can prevent the unnecessary update terminations in EWM. It also ensures stability for custom code using this functionality.
Further checks are under development and will follow on a regular basis, refer to the SAP Note 3018957.
SAP EarlyWatch Alert tool also provides application specific checks for Transportation Management (TM) are available since July 2021.
