Maintenance Transaction Step Sequence 
The Maintenance Optimizer contains several scenarios. There are some steps common to all scenarios:

Depending on the scenario selected, the Maintenance Optimizer automatically adds further steps to the standard procedure.
The system assigns a status to each step you perform. You can repeat previous steps until the transaction has the status Completed. Then you can no longer change the maintenance transaction.
The Maintenance Optimizer can automatically calculate the download files required, independently of the scenario which you select for the maintenance transaction.
The Maintenance Optimizer automatically calculates the files required for the maintenance transaction, based on the defined system landscape, in the following additional steps:

Recommendation
You are planning to update associated development, quality assurance and production systems, and want to ensure that you perform the same maintenance activities in all the systems, regardless of the time betwen their updates. Select all the systems in step 1 of the maintenance transaction, and perform a maintenance transaction for them. The stack files are calculated and made available for all the systems at the same time.
Recommendation
If the original system and the system in which the stack file is to be implemented have the same initial and target constellations, you can copy the stack file in a report.
