Introduction of application specific Extended Warehouse Management Checks in SAP EarlyWatch Alert
Beginning of March 2021, the SAP EarlyWatch Alert service was enhanced to reflect application checks for SAP Extended Warehouse Management (EWM).
This new functionality was initiated via collaboration between the SAP Mission Control Center, SAP Extended Warehouses Management (EWM) experts, and SAP Customer Success targeting all SAP EWM customers who send data to SAP.
The automated service analyzes the essential administrative services of the customer systems, alerts on any critical situations and offers recommendations/solutions to improve performance and stability .
These alerts 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 were 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

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.
Recommendation on Latest Support-pack for EWM
This check is introduced to alert Customer with a ‘YELLOW’ rating in case the customer is on a support pack which is 5 Support-packs lower than the latest available Support-pack for the EWM version installed in their system.
Recommendation is for Customer to evaluate their upgrade strategy in order to get all new functionalities or latest corrections which may be relevant for their business process.
Missing important EWM SAP Notes for Stock Inconsistencies
Missing / not implementing the important SAP Notes could have many impacts in the Customer system.
This check is introduced to alert Customer with a ‘YELLOW’ rating in case they are missing the most important EWM SAP Notes for Stock Inconsistencies with are relevant for the Support-pack installed on their EWM System.
There is plan to extend this check for other components of EWM in the near future.
Saved Queues in SMQ3 older than 365 days
This check is introduced to alert the Customer with a ‘YELLOW’ rating in case there are queues saved in SMQ3 which are older than 1 year.
Recommendation is to evaluate all the queues older than 365 days saved in SMQ3. If the queues are relevant for Business, restore them to SMQ2, fix the error and process the queues.
If the queues are no longer needed, perform the necessary cleanup activities based on SAP Note 2558561
Recommended Background Jobs not set up in EWM
This check is introduced to alert Customer with a ‘YELLOW’ rating in case there are some of the recommended background jobs missing and a ‘RED’ rating in case only 40% of the recommended background jobs are set up for EWM.
The check is performed for the Generic jobs on customer systems and link to the SAP Service Market place for EWM Operations guide for the scenario specific jobs relevant for the Customer is recommended.
Archiving not set up for EWM Objects
This check is introduced to alert Customer with a ‘YELLOW’ rating in case archiving is missing for some of the recommended EWM Objects (i.e. more than 50% of the recommended objects in EWM have the archiving set up) and a ‘RED’ rating in case only up to 50% of the recommended EWM Objects have the set up for archiving
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.
