Production Issues

Hi All...here is the list of SAP BI Production Support issues along with the resolution. Hope it will be helpful for the people who are working in support environment.

1. DTP Failure

Select the step-> right click and select “Display Message”-> there we will get the message which gives the reason for ABEND.

A DTP can failure due to following reasons, in such case we can go for restarting the job.

·       System Exception Error

·       Request Locked

·       ABAP Run time error.

·       Duplicate records

·       Erroneous Records from PSA.

Duplicate records:

            In case of duplication in the records, we can find it in the error message along with the Info Provider’s name. Before restarting the job after deleting the bad DTP request, we have to handle the duplicate records. Go to the info provider -> DTP step -> Update tab -> check handle duplicate records -> activate -> Execute DTP. After successful competition of the job uncheck the Handle Duplicate records option and activate.

DTP Log Run:

·       If a DTP is taking log time than the regular run time without having the back ground job, then we have to turn the status of the DTP into Red and then delete the DTP bad request (If any), repeat the step or restart the job.

·       Before restarting the Job/ repeating the DTP step, make sure about the reason for failure.

·       If the failure is due to “Space Issue” in the F fact table, engage the DBA team and also BASIS team and explain them the issue. Table size needs to be increased before performing any action in BW. It’ll be done by DBA Team. After increasing the space in the F fact table we can restart the job.

Erroneous Records from PSA:

     When ever a DTP fails because of erroneous records while fetching the data from PSA to Data Target, in such cases data needs to be changed in the ECC. If it is not possible, then after getting the approval from the business, we can edit the Erroneous records in PSA and then we have to run the DTP.

Go to PSA -> select request -> select error records -> edit the records and save.

Then run the DTP.

2.      INFO PACKAGE FAILURE:

The following are the reasons for Info Pack failure.

·       Source System Connection failure

·       tRFC/IDOC failure

·       Communication Issues

·       Processing the IDOC Manually in BI

·       Check the source system connection with the help of SAP BASIS, if it is not fine ask them to rebuild the connection. After that restart the job (Info Pack).

Go to RSA1 -> select source system -> System -> Connection check.

·       In case of any failed tRFC’s/IDOC’s, the error message will be like “Error in writing the partition number DP2” or “Caller 01, 02 errors”. In such case reprocess the tRFC/IDOC with the help of SAP BASIS, and then job will finish successfully.

   

·       If the data is loading from the source system to DSO directly, then delete the bad request in the PSA table, then restart the job

·       Info Pack Long Run: If an info pack is running long, then check whether the job is finished at source system or not. If it is finished, then check whether any tRFC/IDOC struck/Failed with the help of SAP BASIS. Even after reprocessing the tRFC, if the job is in yellow status then turn the status into “Red”. Now restart / repeat the step. After completion of the job force complete.

·       Before turning the status to Red/Green, make sure whether the load is of Full/Delta and also the time stamp is properly verified.

·       Time Stamp Verification:

Select Info Package-> Process Monitor -> Header -> Select Request -> Go to source System (Header->Source System) -> Sm37-> give the request and check the status of the request in the source system -> If it is in active, then we have to check whether there any struck/failed tRFC’s/IDOC’s

If the request is in Cancelled status in Source system -> Check the Info Pack status in BW system -> If IP status is also in failed state/cancelled state -> Check the data load type (FULL or DELTA) -> if the status is full then we can turn the Info Package status red and then we can repeat/restart the Info package/job. -> If the load is of Delta type then we have to go RSA7 in source system-> (Compare the last updated time in Source System SM37 back ground job)) Check the time stamp -> If the time stamp in RSA7 is matching then turn the Info Package status to Red -> Restart the job. It’ll fetch the data in the next iteration

If the time stamp is not updated in RSA7 -> Turn the status into Green -> Restart the job. It’ll fetch the data in the next iteration.

Source System	BW System	Source System RSA7	Source System SM37	Action
I/P Status RED(Cancelled)	I/P Status (Active)	Time stamp matching with SM37 last updated time	Time stamp matching with RSA7 time stamp	Turn the I/P Status into Red and Restart the Job
I/P Status RED(Cancelled)	I/P Status (Cancelled)	Time stamp matching with SM37 last updated time	Time stamp matching with RSA7 time stamp	Turn the I/P Status into Red and Restart the Job
I/P Status RED(Cancelled)	I/P Status (Active)	Time stamp is not  matching with SM37 last updated time	Time stamp is not matching with RSA7 time stamp	Turn the I/P status into Green and Restart the job
I/P Status RED(Cancelled)	I/P Status (Cancelled)	Time stamp is not  matching with SM37 last updated time	Time stamp is not matching with RSA7 time stamp	Turn the I/P status into Green and Restart the job

·       Processing the IDOC Manually in BI:

When there is an IDOC which is stuck in the BW and successfully completed the background job in the source system, in such cases we can process the IDOC manually in the BW.

Go to Info Package -> Process Monitor -> Details -> select the IDOC which is in yellow status(stuck) -> Right click -> Process the IDOC manually -> it’ll take some time to get processed.

******Make sure that we can process the IDOC in BW only when the back ground job is completed in the source system and stuck in the BW only.

3.      DSO Activation Failure:

When there is a failure in DSO activation step, check whether the data is loading to DSO from PSA or from the source system directly. If the data is loading to DSO from PSA, then activate the DSO manually as follows

·       Right click DSO Activation Step -> Target Administration -> Select the latest request in DSO -> select Activate -> after request turned to green status, Restart the job.

·       If the data is loading directly from the source system to DSO, then delete the bad request in the PSA table, then restart the job

4.      Failure in Drop Index/ Compression step:

When there is a failure in Drop Index/ compression step, check the Error Message. If it is failed due to “Lock Issue”, it means job failed because of the parallel process or action which we have performed on that particular cube or object. Before restarting the job, make sure whether the object is unlocked or not.

There is a chance of failure in Index step in case of TREX server issues. In such cases engage BASIS team and get the info reg TREX server and repeat/ Restart the job once the server is fixed.

Compression Job may fail when there is any other job which is trying to load the data or accessing from the Cube. In such case job fails with the error message as “Locked by ......” Before restarting the job, make sure whether the object is unlocked or not.

5. Roll Up failure:

“Roll Up” fails due to Contention Issue. When there is Master Data load is in progress, there is a chance of Roll up failure due to resource contention. In such case before restarting the job/ step, make sure whether the master data load is completed or not. Once the master data load finishes restart the job.

6. Change Run – Job finishes with error RSM 756

      

When there is a failure in the attribute change run due to Contention, we have to wait for the other job (Attribute change run) completion. Only one ACR can run in BW at a time. Once the other ACR job is completed, then we can restart/repeat the job.

We can also run the ACR manually in case of nay failures.

Go to RSA1-> Tool -> Apply Hierarchy/Change Run -> select the appropriate Request in the list for which we have to run ACR -> Execute.

7. Transformation In-active:

In case of any changes in the production/moved to the production without saving properly or any modification done in the transformation without changing, in such cases there is a possibility of Load failure with the error message as “ Failure due to Transformation In active”.

In such cases, we will have to activate the Transformation which is inactive.

Go to RSA1 -> select the transformation -> Activate

In case of no authorization for activating the transformation in production system, we can do it by using the Function Module - RSDG_TRFN_ACTIVATE

Try the following steps to use the program "RSDG_TRFN_ACTIVATE” here you will need to enter certain details:

Transformation ID: Transformation’s Tech Name (ID)

Object Status: ACT

Type of Source: “Source Name”

Source name: “Source Tech Name”

Type of Target: Target Name

Target name: “Target Tech Name”

A.     Execute. The Transformation status will be turned into Active.

Then we can restart the job. Job will be completed successfully.

     8. Process Chain Started from the yesterday’s failed step:

In few instances, process chain starts from the step which was failed in the previous iteration instead of starting from the “Start” step.

In such cases we will have to delete the previous day’s process chain log, to start the chain form the beginning (from Start variant).

Go To ST13-> Select the Process Chain -> Log -> Delete.

Or we can use Function Module for Process Chain Log Deletion: RSPROCESS_LOG_DELETE.

Give the log id of the process chain, which we can get from the ST13 screen.

Then we can restart the chain.

Turning the Process Chain Status using Function Module:

At times, when there is no progress in any of the process chains which is running for a long time without any progress, we will have to turn the status of the entire chain/Particular step by using the Function Module.

Function Module: RSPC_PROCESS_FINISH

The program "RSPC_PROCESS_FINISH" for making the status of a particular process as finished.

To turn any DTP load which was running long, so please try the following steps to use the program "RSPC_PROCESS_FINISH" here you need to enter the following details:

LOG ID: this id will be the id of the parent chain.

CHAIN: here you will need to enter the chain name which has failed process.

TYPE: Type of failed step can be found out by checking the table "RSPCPROCESSLOG" via "SE16" or "ZSE16" by entering the Variant & Instance of the failed step. The table "RSPCPROCESSLOG" can be used to find out various details regarding a particular process.

INSTANCE & VARIANT: Instance & Variant name can be found out by right clicking on the failed step and then by checking the "Displaying Messages Options" of the failed step & then checking the chain tab.

STATE: State is used to identify the overall state of the process. Below given are the various states for a step.

R Ended with errors

G Successfully completed

F Completed

A Active

X Canceled

P Planned

S Skipped at restart

Q Released

Y Ready

Undefined

J Framework Error upon Completion (e.g. follow-on job missing)

9. Hierarchy save Failure:

When there a failure in Hierarchy Save, then we have to follow the below process...

If there is an issue with Hierarchy save, we will have to schedule the Info packages associated with the Hierarchies manually. Then we have to run Attribute Change Run to update the changes to the associated Targets. Please find the below mentioned the step by step process...

ST13-> Select Failed Process Chain -> Select Hierarchy Save Step -> Rt click Display Variant -> Select the info package in the hierarchy -> Go to RSA! -> Run the Info Package Manually -> Tools -> Run Hierarchy/Attribute Change Run -> Select Hierarchy List (Here you can find the List of Hierarchies) -> Execute.
