Rebuilding Data Extracts
Use
This utility copies an existing extract into a new extract, using the latest DART configuration definitions. This allows you to impose a new configuration on existing extracted data.
For example, if you have defined a new index on a segment, you can use this utility to apply the new index to the segment in the data extract.
Prerequisites
The data extract you copy must have been created with the DART data extraction utility.
Procedure
|
Field/Group |
Action |
|
Source extract |
Enter the source extract name and its directory set. |
|
Other data |
Set the Extract customer-defined data sources indicator to include data as specified by customer-defined segments. |
|
Target extract(Data extract name, Directory set) |
Enter the target extract name and its directory set. |
|
Description |
Describe the target extract or the reason for the rebuild. |
|
Note icon |
Enter a note explaining the reasons for the rebuild in more details. |
|
Merge source extract notes |
Set this indicator if you wish to include the notes from the source extract in the rebuilt target extract. Regardless of your selection in this field, the system includes a short description of the source extract as part of a note included in the target extract. If you enter any note for the rebuilt extract, then the note in that extract includes three parts: your note for the source extract, the system note, and your note for the target extract. |
|
Compress data |
Set this indicator to compress the rebuilt extract. You may use any setting regardless of whether the source extract had been compressed or not. |
|
Calculate data checksums |
Set this indicator to include checksums for the segments in the target extract. |
|
Fill customer-defined fields |
Set this indicator to include data for customer-defined fields that were added to the SAP-provided segments. |
Result
The system copies the data from one extract to another.
The system recreates any configuration elements that have been defined since the data was extracted. For example, it recreates:
The system may restructure the extracted data files differently as a result of the new configuration. For example, if you have specified a different maximum file size, the utility may need to reorganize the data into a different amount of physical files.
The system may also extract additional data that was not included in the original extract (and is therefore not in the source file):
