Please note that the content of this article is relevant only for SCM_BASIS Version 7.0 and subsequent versions by default. If the content is applicable to SCM_BASIS 5.0 or 5.1, that will be indicated.


The purpose of this page is to provide useful hints and info on working with SCM APO - SDP, FCS and PPS alerts.

Alert Monitor in SCM User Assistance Page (SAP Help).


The Alert Monitor is a valuable tool for monitoring exceptions within the system. It uses event triggers and alarm conditions established during planning and scheduling to automatically identify problems in the supply chain. It monitors factors such as material, capacity, transportation and storage constraints, as well as metrics such as delivery performance, cost flow and throughput.

The main transaction for AMO is /N/SAPAPO/AMON1

The alert types can be managed in /N/SAPAPO/AMOCFG

The Alert Monitor related tables > Transaction code SE11: /SAPAPO/AM* + F4 help

In essence, the Alert Monitor is a tool used by planners to monitor the state of planning in the system, and the actual alerts serve as guidelines for replanning.

The attached document contains detailed information and useful hints on SDP and FCS Alerts.

Please note that the Alert Engine has been reorganized at SCM 7.0. You can meet several differences in the coding, the alert determination process and in the User Interface as well after an upgrade from eg. 5.0, 5.1 to 7.0 or higher.

Alert Creation:

  • Depending on the SCM application the alerts can be database or dynamic alerts.
  • Database alerts are created by the application itself for example in case of SDP macro executions in transaction /N/SAPAPO/MC8G. Such jobs can fill the alert database tables with the necessary entries.
  • Dynamic alerts are stored at transaction data level and always maintained real-time.

Alert determination:

Alert Monitoring Overall profile: (from here the application alert profiles are called)

PP/DS Resource Alerts:

To be able to determine the resource capacity load alerts in the Alert Monitor, please make sure to define a value other than 0 to the two fields Underload Alerts from (%) and Overload Alerts fr.(%) . This two fields reflect the static threshold values instead of the 3 level threshold which used in general to alert types, and these fields must not be equal to 0. Otherwise the program will not determine any alerts.

Forwarded Alerts:

  • You can forward alerts from the alert grid to another SAP user (Planner) with the ''Envelope'' button. This will be shown to the addressed user every time she determines alerts, with an envelope sign on it. It can be acknowledged with the ''Undo" button (that clears any type of status icons from the alerts)

  • Forwarded status is stored in the /SAPAPO/AM_FRWD database table.

Show alerts on the alert grid (ALV view in e.g. /sapapo/amon1 transaction)

The determined alerts are displayed on a table view solution, called ALV view. This provides with a structured display of the alerts, with additional functions, such as exporting to an excel sheet. Although this display mode is created for dialog usage and not to process huge amount of records. Therefore in case of more thousand entries, the alert methods may not be able to pass the data to the ALV program. Therefore please consolidate the selection criteria of the alerts to be displayed for a realistic, dialog mode usage.

/SAPAPO/ALERT_MONITOR class , method > show_alerts

Performance of the Alert Monitor:

Different alert types can be determined for many SCM applications and especially the database alert types are distributed in several alert database tables. Mostly database alert types can grow into huge amount entries. Reading them as a whole can take time, therefore a reasonable selection criteria is highly advised to set up in the /SAPAPO/AMON1 transaction. Please use different selection fields such as product, location and date-time interval. It is also advised NOT to include every database alert type (AOT, AT_ID) into one profile, but to separate them into more profiles.

If the alert determination still takes a considerable amount of time in the dialog mode, it is advised to set up background alert jobs, for obtaining saved alert situations. For more information please see: Alert Determination in the Background / Saved Alert Situations 

Please also consider to regularly remove obsolete records from the database, see ''Deletion of alerts''

Database Tables:

Alert Monitoring tables can be found from SE11 or SE16 transactions by typing /SAPAPO/AM* and pressing F4 help. This lists out most of the relevant tables.

  • /SAPAPO/AM_NOTE > this table stores the actual entries that you see in the ALV view in eg. /SAPAPO/AMON1 or in the respective application. The info fields (1-4) includes the alert entry's details. MANDT / NOTE_ID is the key of the table.

  • /SAPAPO/AM_NOTES > Different alert statuses eg. Take note of alert's tag is found here, this table stores the alert status. MANDT / NOTE_ID / USERNAME / STATUS are forming the key. Therefore the take note of alerts can be differentiated by logon user.

  • /SAPAPO/ALERT_HP > PP/DS database alerts.

  • /SAPAPO/AM_ALERT > Database Alerts
  • /SAPAPO/*ALERT* > F4 help can reveal more
  • /SAPAPO/AM* > F4 help can reveal more


Authorization objects for Alert Monitor:

There are two objects existing for Alert Monitor authority checks: C_APO_AMON and C_APO_APRF.

Please see note: ''2042570 - Authorization checks for profile is not called in the Alert Monitor'' in order to set up the possible authorization routes for Alert Monitor for different users.

Alert Determination in the Background / Saved Alert Situations:

The following test case introduces how to create saved alert situations in the background: Background alerts and saved alert situation export to an Excel file or email

Note: When processing background alert determination for more than one Alert Profiles it is important that the first (initial) determination is executed on them one after another. Paying attention to this will secure that the /SAPAPO/AMSAFTY table is maintained with distinct entries (eg. /SCMB/AMOB1, /SCMB/AMOB2) regarding the field: /SAPAPO/AMSAFTY-ALERTDB for each alert profiles. This means that each alert profile, that is saved for background processing will have its own alert database, where its further attributes are stored. After this initial step the background determination can freely be processed in the same time slot for several saved alert profiles (eg. in a parallel setup RSPC chain).

If you meet such issues that one alert profile's saved alert situation overwrites another profile's saved situation, the most possible root cause is that they have the same DB value in the /SAPAPO/AMSAFTY table. This can happen if the previously described initial separated execution was not met. To eliminate this inconsistent state the alert profile's saved for background determination must be deleted and recreated again. This can be done in transaction /SAPAPO/AMON1 / Go To / Favorite Management / Alerts in the background Tab. The same place where they were initially saved. After recreation the initial separated execution is required as described above in order to raise its own unique database.

Deletion of alerts and Alert Tables Housekeeping:

  • report: /SAPAPO/AMODAL_DELETE    > class / method: /sapapo/cl_amodal_manager=>alert_delete_by_list  >>> deletes from DB /SAPAPO/AM_ALERTS
                                                                   > class / method: /sapapo/cl_amonote=>alert_note_del     >>>   deletes from  DB /SAPAPO/AM_NOTE, /SAPAPO/AM_NOTES,  /SAPAPO/AM_NOTEP, /SAPAPO/AM_FRWD
  • report: /SAPAPO/AMON_REORG          > class / method:  /sapapo/cl_amodal_manager=>alert_delete_by_list >>> deletes from /SAPAPO/AM_ALERTS, sapapo/alert_vm, and other application tables

Keep in mind that these reports can become very memory intensive, if the alert storage tables are overgrowing. Please set up proper selection criteria including alert object types, alert types, and date intervals, in the initial screen to avoid memory dumps, also try to prevent the data overload by maintaining these tables regularly.

Please consider the data volume on both the above mentioned tables, as well as in the generated database tables e.g.: /scwm/alert2501
