Change History for Cover Groups 
If you have created several cover eligibility (CE) rules with automatic, manual or revenue cover groups, you may need to track the changes made to these cover groups, since:
The attributes of the cover groups involved may have changed.
Budget addresses may have been added or removed from the cover groups.
The attributes of the assigned budget addresses may have changed.
The following prerequisites apply:
You have activated cover eligibility for your organization (FM area) in Customizing.
You have activated the recording of change documents for cover groups in Customizing.
You have created CE rules with automatic, manual or revenue cover groups, either manually using transaction FMCERULE, or by using the derivation strategy for generating cover groups, in combination with transaction FMCEGENCG.
To see the changes made to specific cover groups or CE rules, go to the SAP Easy Access menu: Accounting Public Sector Management → Funds Management → Master Data → Use of Account Assignment Elements → Budget Control System (BCS) → Cover Eligibility → Cover Eligibility Rule → Create Change History List (Transaction FMCEHISCG). Proceed as follows:
Enter the FM area, fiscal year and budget category. The budget category (9F or 9G) for selecting change documents of an automatic cover group is the budget category of the AVC ledger to which the automatic cover group is assigned. The budget category for selecting change documents of a revenue cover group is the corresponding budget category of the RIB ledger (or budget category for RIB) to which the revenue cover group is assigned.
Make restrictions applying to cover groups or to budget addresses assigned to them.
In the section Restriction to User Logs , you can enter specific user names (who made the changes) and/or dates (when the changes were made) for selection.
Run the report.
The output list contains thefollowing information:
All document numbers of the change documents (change records)
The date, time, and type of change
The cover group involved, as well as the assigned budget addresses and their roles (sending, receiving or both, for automatic or manual cover groups; contributor or RIB source address for revenue cover groups)
The user responsible for the change
The old and new values of the changed fields

If you have only changed the attributes of the cover group, the output list will nevertheless contain two lines, one for the cover group table itself, and one for the text table involved.
You can print or export this list, as well as send it via email to the colleagues that may need to access this information.
There is a deletion program for cover group change logs, enabling you to delete old change history records for performance reasons. Access this deletion program in the Customizing for Public Sector Management under Funds Management → Budget Control System → Budgeting → Cover Eligibility → Cover Eligibility Rule → Delete Change Log for Cover Eligibility
If you want to use the functionality of change documents for cover groups, you must first activate this in Customizing activity Activate Change Log for Cover Eligibility in Customizing for Public Sector Management under Funds Management Government -> Budget Control System (BCS) -> Budgeting -> Control Budgeting Flow -> Cover Eligibility . If you do not want to use the change history function for cover groups, you can leave the update of change records deactivated, which improves performance when you run the maintenance transactions for cover groups.
