BW: Error 1 when loading external data
Although SAP has a pretty long message when you encounter Error 1 , it’s not to the point enough to make the debugging easier. In my case, the reason is that the file was open. Close the file, everything was fine. Diagnosis Error number 1 occurred when loading external data: 1. Error when reading the [...]

RSRV
RSRV performs consistency checks on the data and metadata stored in a BW system. Error with partition when loading Error: Communication errors (RFC) DBIF_RSQL_SQL_ERROR CX_SY_OPEN_SQL_DB ORA-14400: inserted partition key does not map to any partition Internal call code………: “[RSQL/INSR//BIC/B0000xxxxxx ]” Solution: RSRV -> PSA Tables -> Consistency Check for PSA Error calling number range object [...]

CUBE_SAMPLE_CREATE
This program allows you to be really lazy if you want to have some sample records in a InfoCube. No need to use flat files, edit the value in a ALV-Grid or let the system generates random values for you. It works only on InfoCube, not ODS. Works for BW3.5 and BI7.0 The records are added to the [...]

Activate Business Content DataSources
Sometimes, it’s easier to use existing Business Content DataSources, espeically for master data text or attribute. SBIW -> DataTransfer to SAP Business Information Warehouse -> Business Content DataSources -> Transfer Business Content DataSources -> Find the name of the DataSource name -> Activate DataSources To find a standard dataSource, click on the top node: SAP -> [...]

Different loading errors on Fisical period when using a non-reasonable date
Yesterday, one BW load failed because the date user used in R3 is 01/01/9999, and this date let’s call it valid_from, is the source field to convert to fisical date/Calendar date and so on. Below is a list of errors I got. Time conversion from 0CALDAY to 0FISCPER (fiscal year ) failed with value 01019999 This happens when [...]

Change timezone on BW
This change affects the timestamps on data loads in BW monitor. It should be done when no load is running. Go to t-code SPRO –> Click on SAP Reference IMG button You should see a new screen ‘Display IMG’.Follow the path in the hierarchy.. SAP Customizing Imp Guide->SAP NetWeaver->General Settings->Time Zones->Click on ‘Maintain System Settings’. [...]

Data loading package size
Package = Packet Transfer structure size = Table length In OLTP system: SBIW — General Settings — Maintain General settings for extractors Actually change table ROIDOCPRMS in which MAXSIZE, MAXLINES are set for the BW system. Memory Size = MAXSIZE * 1000 / size of the transfer structure Package size = (Memory Szze < MAXLINES) [...]

Can I do a full load for a data target that already init and delta?
Yes, just use Repair FULL request option. Select an Info package –> From the top menu –> Select Scheduler –> reparir full request. Full Repair request is used to load historical data for missing objects for transaction as well as for master data. for example: think that you are loading daily deltas from 0MAT_PLANT to [...]

delta update invalidated
SAP error: Delta update for [a cube] is invalidated Message no. RSBM113 Diagnosis The delta update for the InfoCube is invalidated. The can be due to one of the following: 1. A request, which was already retrieved from the target system, was deleted from the InfoCube. 2. A request, which was not yet retrieved from [...]

No source system ID exists for source system (logical system)
When loading some master data, get following error: No source system ID exists for source system (logical system) To assign a source system ID to the logical system: Administrator Workbench > Tools > Assign source system to source system ID. Assigning a source system to a source system ID is necessary if, for example, you [...]

InfoObject xxxxxx does not contain alpa-conforming value xx
BW3.5 Noticed through RSMO, the error is inside the “Transfer Rules”. Go to the Transfer rule tab of the infoSource, on the left side, the last column is: Run Optional Conversion in the Transfer Rules If it can be checked, check the box.

Delete not used master data
You can delete the values that are not used from a characteristic using the report RSDMD_DEL_BACKGROUND.You have to execute the report with the following parameters: P_IOBJNM = (Technical name of characteristic) P_CHABNM = (Technical name of reference characteristic) P_DELSID = ‘X’ (Delete SID?) P_DELTXT = ‘ ‘ (Delete text?) P_OBJ = RSDMD (Application log obj name) [...]

How to find out whether the index is bitmap or B-tree?
With Oracle DB, setting the Cardinality option causes a b-tree index to be built instead of a bitmap index even if it is not a line item dim. Setting it as a Line Item dim also causes a b-tree index to be built instead of a bitmap index, but also embeds SID directly in the [...]

ODS activation failed with error message: ODS object was built incorrectly
Platform: BW3.5 Scenario: ODS ZA was updated by 3 other source ODSs, ZB, ZC, ZD using delta for about a year. ZA, ZB, ZC, ZD are in the process chain loading daily. ODS ZE was newly added to be updated from ZB. Init was done on the weekend for ZE. Delta was added to the same process chain. [...]

BW InfoSoure
BW 3.x InfoSources are sets of logically-related InfoObjs that are available in the form of a communication structure. Multiple DataSources can be assigned to an InfoSource, either from different source systems or not. Exceptions: Only one source system for hierarchies InfoSource. In transfer rule maintenance, you assign DataSource to InfoSource; determine whether the communication structure [...]

Data Mart Delta
In ODS to cube/ods data mart, data is extracted using function module RSBX_BIW_GET_ODSDATA. Delta setting can be seen in RSA2. Data source are generated automatically during setup. They can be found through RSA6 (RSA5 for Business content) — BW – DM Data mart delta in myself BW system sometimes can be found in RSA7, sometimes not. Checking the following tables, if the data mart name is not in [...]

Data Mart InfoPackage: Could not make connection to source system
Edit an infoPacage, in Data Selection tab, select an infoObj of “Date” type, click on the round selection button, usually, the calendar pops up, but not for Data Mart (of the same BW system). Message no. RSAOLTP150 No solution on this issue so far.


Create BW infoSet and other SAP hidden tricks
Posted on May 31st, 2008
There are loads of document on how to create infoSet (BW infoProvider, not R3 infoSet). However, I encounted something unexpected the first time when I tried to create one. I was supposed to get a screen like this: However, my screen looks like this: I went through all the menus and setttings trying to find [...]

sap extract
Posted on February 4th, 2008
Since internal tables have fixed line structures, they are not suited to handle data sets with varying structures. Instead, you can use extract datasets for this purpose. An extract is a sequential dataset in the memory area of the program. You can only address the entries in the dataset within a special loop. The index [...]

Posted on February 4th, 2008
Add the following statement to the TOP include of your function group. Type-pools: SRSC. The problem is that the TYPE has not be defined in your program, but in a TYPE Group or Type Pool. You need to reference the TYPE group when using that type. If you drill into the TYpe group statement above, [...]

Delta load — missing data, corrupted data
Posted on February 4th, 2008
It’s kind of scary to do init full load for delta whenever there’s a problem with data. I am trying to gather what’s the best we can do, and what’s the catch. Question: I have loaded Inventory Data( Historical Stock Balances by using 2lis_03_BX) in to InfoCube 0IC_C03 from the year 2001 April. First we [...]

Check dimension size
Posted on February 4th, 2008
The current size of all dimensions can be monitored in relation to fact table by t-code se38 running report SAP_INFOCUBE_DESIGNS The ratio of a dimension should be less than 10% of the fact table. In the report, Dimension table looks like /BI[C/O]/D[xxx] Fact table looks like /BI[C/0]/[E/F][xxx] Use T-CODE LISTSCHEMA to show the different tables [...]

How to copy a cube and data
Posted on February 4th, 2008
To copy CubeA to CubeB: Option 1: If CubeA is updated from ODS and ODS has all data you wanted, you can create update rules for CubeB and update it from ODS. This option can be used if no records has been deleted from ODS. Option 2: Right click on ‘Generate Export Datasource’ on CubeA [...]

Delete PSA and ODS change logs

In the InfoCube maintenance choose Extras ® Partitioning, and specify [...]

Balanced and unbalanced hierarchies
Posted on December 16th, 2007
In balanced hierarchies (balanced/standard), the branches of the hierarchy all descend to the same level, with each member’s parent being at the level immediately above the member. An common example of a balanced hierarchy is one that represents time, where the depth of each level (year, quarter, and month) is consistent. Unbalanced hierarchies includes levels [...]

Line Item, High Cardinality ,degenerated dimension
Posted on December 16th, 2007
Line item: the dimension contains precisely one characteristic. High cardinality: the values in dimension table are not repeated in fact table. E.g. sales document number. degenerate dimension: size of a dimension starts to increase and approaches the size of fact table, the dimension only contain one characteristic. item. The solution is to mark the dimension [...]
