Check setup tables R/3

When using report rmcex_setup_entries in R/3 one can easily show the contents of all the setup tables in R/3.

Also you have the ability to jump to LBWG transaction to delete contents of setup tables of a particular application.

0FI_*_4 datasource

For the 0FI_*_4 datasource the following tables are being used in R/3 / ECC.

General Ledger

0FI_GL_4 > BSEG/BKPF

Accounts Receivable

0FI_AR_4 > BSIK / BSAK

Accounts Payable

0FI_AP_4 > BSID / BSAD

Taxes

0FI_TX_4 > BSET

If 0FI_GL_4 datasource is used, its timestamp is also leading for the other 0FI_*_4 datasources. Timestamps of the datasources can be found in table BWOM2_TIMEST.

Standardly a delta request on leading datasource 0FI_GL_4 picks up all changes up to the day before if load is started after 02:00 AM of systemtime. There is a safety margin of two hours build in to sustain a certain consistency between R/3 and BW.

Cleaning up statistic tables in BI

In order to keep your BI system healthy, it's necessary to clean-up some statistical tables once in a while. Especially in BI 7.0 I experienced some tables growing rapidly (e.g. DTP statistics).

In RSA1 goto Tools à Settings for BI Statistics.

Choose and select the tables you want to clean up:


Which option cleans which tables? Here you go:

Option

Tables

Query Statistics Tables

RSDDSTATHEADER, RSDDSTATDM, RSDDSTATEVDATA, RSDDSTATAGGRDEF, RSDDSTATINFO.

Statistic Loggin Tables

RSDDSTATLOGGING

Aggregates/BIA Index Process

RSDDSTATAGGR, RSDDSTATTREXSERV, RSDDSTATTREX,

InfoCube Statistics (Delete, Compress)

RSDDSTATDELE, RSDDSTATCOND

Didn't see this option in 3x System. There you can execute the same program manually: RSDDSTAT_DATA_DELETE.

Is your 'huge' table not here, maybe this will help:

Datasources

Tables

0TCT_DS01, 0TCT_DS02, 0TCT_DS03

RSDDSTATHEADER,

RSDDSTATINFO

RSDDSTATEVDATA

RSDDSTATDM

By loading Technical content, data in these tables is automatically saved for 14 days. To change the # of days: change parameter TCT_KEEP_OLAP_DM_DATA_N_DAYS in table RSADMIN.

Last but not least: Table BALDAT (Application Log) can be cleaned with tcode SLG2.

Good luck!

Analyzing Throughput Times Process Chains

To analyze your process chains in SAP BI (but also other BI elements, SAP provides the program /SSA/BWT.

How to use:

Select the first bullet after running the program in SA38:

Enter the technical name of the process chain to be analyzed:

In the following screen you can see all details of the different process chain runs, but also compare different process chain runs with each other.

This program is very useful when you want to analyse why a certain process chain is taking longer.

Try it out!

Solving delta queue issues after system copy

Always make sure you empty ALL delta queues on ECC before doing a system copy. Stop the V3 jobs and run the infopackages. After system copy the queues between ECC-BW are not aligned anymore.

After a system copy or refresh of the R/3 source system, you may encounted dumps in your BI system when you want to initialize (logistic) data flows.

Mostly it occurs that in R/3 there are no activated delta queues, but in BI the Infopackages still contain the Init entry. The system dumps when you want to open the Infopackage, making it impossible to delete the Init entry there!
To solve this you have to run program RSSM_OLTP_INIT_DELTA_UPDATE in your BI system.
Fill in the fields. If you are sure, mark ALWAYS with X and execute the program.
After this action you can open your InfoPackage again and initialize the delta queue!
