DTP: Track records after failed request

There is an option available for DTPs on its Update tab called “Track Records after Failed Request”. When it is checked, it means that BW systems builds cross-reference table. The cross-reference table that is built when the upload request fails. The table traces an erroneous records of the data load.

This option can only be selected when error handling is set to “Terminate request; no record tracing; no updating”, e.g. when error handling is deactivated.

This option helps performance of data load because there is no tracking of error records during data load process.

Normally when the option is checked for a particular DTP there is a warning message as below shown:

'Attribute 'Automatically Switch Record Tracking On: Value 'X' is obsolete'. RSBK453

This message is shown as there are certain checks executed by a method _CHECK_GENERAL call (of class CL_RSBK_DTP_V). This method calls another one CL_RSBK_DTP_API=>ADMISSIBLE_GET that populates the value. If the check box is enabled the values is equal to following attribute: CL_RSBK_DTP_API=>C_S_ATTRIBUTE-TRACK_RECORDS.

Just to add; SAP recommends (e.g. here for BW/4/HANA or for DataSphere) activating error handling only if errors occur during execution of the DTP. So not by default. If error handling is activated, the data records with errors are written to the data transfer intermediate storage, where they can be corrected before being written to the data target using an error DTP.

Deleting error stack of DTP via ABAP

Error stack of DTP is function that is very useful in scenarios where data is not coming in proper format. While using it erroneous records are filtered out and only those which are correct are uploaded into data target. Later on BW administrator can correct the erroneous records and upload it too.

Below there is the error stack req ID 2.115.361 as depicted in DTP’s maintenance screen:

Now imagine that this error stack req is snot needed any more. We can also see it via ABAP report RSB_ANALYZE_ERRORLOG. The report provides a list of all available error stacks request in the system while analyzing contents of error tables:

To delete the error stack data of particular request we can use ABAP report: RSBM_ERRORLOG_DELETE while specifying particular DTP’s ID and ticking off “Delete Log” check box:

This is how output of RSBM_ERRORLOG_DELETE report looks like. After that the error stack req is not visible from RSB_ANALYZE_ERRORLOG either in t-code RSA1.
