Synchronizing Contents with the HANA Repository

The sync function uploads the most recent content from the HANA repository and saves it in the ABAP repository.

Prerequisites

You have already created a proxy (or external view) for the database procedure (or HANA view) as a development object in the ABAP system.

Context

Since the creation of a proxy (or external view), the implementation of the related database procedure (or HANA view) may have changed meanwhile in the HANA repository. To reference the current content of the HANA repository from a proxy (external view) definition, it is occasionally necessary to perform an upload to the ABAP repository. The editor of the database procedure proxy (or external view) provides a corresponding sync function for this purpose.

Remember

This kind of inconsistency between the HANA and the ABAP repository object would be detected, at the latest when the proxy (external view) is activated or even already during the check function.

Procedure

To synchronize an external view ...
1. Open the relevant external view in the editor.
2. Click the button Synchronize.
  An information dialog appears.

3. On the dialog window, choose Yes to continue.
4. Save the editor content.
To synchronize a DB procedure proxy ...
1. Open the relevant DB procedure proxy in the editor.
2. Click the button Synchronize.
  A merge dialog appears.

3. On the dialog, select the appropriate option(Merge or Replace) and the choose OK to continue.
4. Save the editor content.

Results

The AS ABAP retrieves the most recent definition of the database procedure (or HANA view) from the HANA repository and saves it in the proxy (or external view) definition in the ABAP repository.

Troubleshooting for External Views

Consider that the synchronization procedure may fail under certain circumstances. This is the case, for example, if the data types defined in the underlying HANA view cannot be mapped onto compatible ABAP Dictionary types. In such a case, the synchronization will be cancelled and a corresponding error item is added to the Problems view. To display detailed error information, open the context menu for the respective error item in the Problems view and choose the option Open Import Log (or alternatively use the toolbar menu Navigate > Open Import Log). The import log with detailed error message is then displayed in the ABAP Log view. You can examine the import log for further troubleshooting.
