(Glue-2408) Extraction of SAP Objects Using ODP Framework

In the scenario of ODP framework-enabled data source objects replication, there are four components forming each of the replication processes: Glue Table, ODP fetcher, Glue Table consumer, and Extraction Process. These four components represent a configuration – setting up the source object, the target object, and transformation rules. Following steps navigate you through the preparation of the whole flow – creating all required objects and executing the load.

Creating Glue table

Run transaction /DVD/GLUE.
Click on the Data Dictionary button.
Enter the name of a new table and click Create. You can enter the description of the table.
Under the Attributes tab fill in the Storage ID (for binary storages you must fill in the File storage options too).

6. Under the Fields tab click on Import Fields, choose From ODP, and enter the name of the ODP source. The structure from the ODP framework object will be imported. You can manually adjust the fields as required.

Import fields

7. Click on the Save button. If the table was not saved before, the system will ask you to fill in the Package. If you have a development package created upfront designated for SNP Glue development, you can use that package. Otherwise, for isolated sandbox purposes, $TMP will do.

Click on the Activate button. Only after you activate the SNP Glue table, it is created on storage.

Creating ODP Fetcher
