You can use the version management functions of the DME Engine to:
Each format tree exists in the following versions:
Calling applications use the active version to generate or convert a DME file. You can also
SAP delivers more than 40predefined format trees that cover various requirements for generating outgoing files in nearly 20 countries. For each of these format trees, SAP provides an active version (000), which can be used to generate files without any further configuration in the DME Engine. Each delivered format tree also comes with version 999, which is an SAP reference version that you cannot change. You can always display it, compare it against any other version, or retrieve it to generate another version from it.
Creating New Format Trees
You can copy any of the delivered trees and use it as a template for creating a new tree – to cover any regional or bank-specific formats not covered by SAP.
Once you save a new format tree, the system saves it as version 001. Once youactivate the maintenance version, it is stored as version 000.
To create additional versions of a format tree, you can:
The system creates a new version from the current maintenance version. The new version becomes the new version 001, and the former 001 is copied to the next subsequent version available.
You select the version you want to retrieve and choose Version ® Retrieve. The system copies this version's contents into a new version 001, and converts the previous maintenance version into the next available version.
Maintaining Format Tree Versions
You always maintain version 001 of a format tree. To do so, specify the tree on the initial screen of the DME Engine and choose Change.
Delivered format trees come with versions 000 and 999. As soon as you modify one of these trees, the system creates a maintenance version, 001, from the active version, 000.
If you choose Utilities ® Versions ® Version Management, you will see that the versions in the development database are always 000 (once you have activated your tree) and 001. The system also displays any versions that exist in the version database. If you are working with a delivered format tree, you will see version 999 here, as well as any other versions you have created.
Comparing Format Tree Versions
You can compare any two versions of a format tree by selecting them and choosing Version ® Compare or . The system displays all differences that exist between the two versions; you can limit the list by displaying changes made only in the header or node attributes, or by displaying only those nodes that were deleted, inserted, or for which the output was delayed.
Assume the following versions exist for your format tree:
Versions in the development database:
Versions in the version database:
You generate a new version, by choosing Utilities ® Versions ® Generate Version. The system copies the current version 001 to a new version, 005, and you can now work with your new version, maintenance version 001.
Later you want to retrieve an earlier version, 002. You choose Utilities ® Versions ® Version Management, select version 002, and choose Version ® Retrieve. The system copies the current maintenance version 001 to a new version, 006, and overwrites 001 with the contents of version 002.
