FM to modify DTP filters

The article: Three Ways to Dynamically Update “Data Transfer Process” Filter Values describes different methods to determine DTP filters dynamically. In particular there is a method that sets the DTP in change mode, modifies the DTP filter then reactivates the DTP.

You can download the code of the function here in Saplink format.

ORA-00060 deadlocks when loading data into InfoCubes

When running DTPs on infocubes with an Oracle DB, a shor dump can occur wit as message:

Runtime error: DBIF_RSQL_SQL_ERROR
Exception: CX_SY_OPEN_SQL_DB
Short text: SQL error 60 while accessing table “/BIC/F<cube name>”
What happened: Database error text: “ORA-00060: deadlock detected while waiting for resource#ORA-00060: deadlock detected while waiting for resource”

This type of errer is explained in Note 631668 – DEADLOCK when loading data into InfoCubes.


Solution: Drop cube index before running DTP and recreate index after.

I recently had to configure a  backup and restore mechanism for an Infocube. The objective was to store one full copy of the source Infocube every day in a backup Infocube that was created as a copy of the source cube plus a “Backup Date” characteristic

To recover a backup in the main Infocube, a transformation from the backup Infocube to the source Infocubehas been setup. One would have to specify the date of the backup that he wishes to restore in the DTP filter of the restore transformation.

To make sure that only one date is entered in the Backup Date characteristic of the DTP filter. I used the following code to check the DTP Filter values in the start routine. The code is based on an example program to output the list of DTP Filters via an ABAP Program posted in SCN (http://scn.sap.com/thread/1150620) you can also download the program is SAPLINK format here.

There is another way to access DTP infomation in the startroutine that I could have used. That is to use the p_r_request object provided in the routine. I did not figure out how to do that when coding the routine, but I later found interesting info on the subject in the following post: http://www.insiderlearningnetwork.com/bics/blog/2010/11/23/how_to_get_selection_criteria_in_transformations_routines
