In Replace merge mode, the process attributes of the newer (last imported) process instance (except for the merge attributes) are transferred to the resulting fragment. For identical functions and events (identical internal object key), the last imported (newer) object replaces the older object including all attributes. Only object attributes and organizational units of the newer (last imported) object are retained. The AT_ORIG_EPK_ID determines which object is newer.
As an option, you can specify a list of process attributes to be transferred from an older process instance to the resulting fragment when merging fragments. The process attribute of the previously imported fragment or the existing process instance is overwritten with the process attribute of the fragment imported later.
In the mergeattributes XML element in the merge configuration, specify a list of process attributes to be transferred when merging fragments. All other process attributes are ignored.
Example
The merge configuration file extract below causes the AT_SAPSYSTEM and AT_SAPCLIENT process attributes to the resulting fragment or an existing process instance when merging fragment instances.
<mergerconfig>
<mergehandling>
<processmerge>
<mergeattributes>
<attribute key = "AT_SAPSYSTEM"/>
<attribute key = "AT_SAPCLIENT"/>
</mergeattributes>
</processmerge>
...
</mergehandling>
</mergerconfig>
Tip
Transferring process attributes enables you to directly overwrite dimension values based on process attributes by importing a fragment that contains only the process attribute with a new value for which the dimension has been created.
Please remember that existing process attributes will be overwritten when you copy object attributes (see Attribute copy rules chapter) at a later time.
If the process attribute is specified for multiple fragments with the same process key, and the import of all fragments is split over several import operations, it is not possible to ensure that the attribute value of the last fragment imported will be transferred to the resulting fragment.
