Live Cache anchor

what is the livecache anchor ? can any one explain in details how it works?
thanks &regards
ravi

Hello,
1)
"Report /SAPAPO/DELETE_LC_ANCHORS must be executed every time after liveCache is initialized. This report ensures the integrity of the APO DB and liveCache data"
It's wrong statement.
For example, the liveCache will be initialized during the version update, when you are using the LCUPDATE tool from the liveCache upgrade CD, but the Report /SAPAPO/DELETE_LC_ANCHORS
should NOT run during the system upgrade. You should NOT run the /SAPAPO/DELETE_LC_ANCHORS program during upload/download procedure (for details, see Note 632357) and when you upgrade to a higher SCM release, since otherwise a loss of data occurs.
Also please pay attention to the SAP note :: 640107 Using program /sapapo/delete_lc_anchors in APO 3.0 or higher.
In the SAP note 640107 is written about steps performed by /sapapo/delete_lc_anchors report.
As it was written in the note, that the /sapapo/delete_lc_anchors program has to be called automatically after the liveCache is initialized in LC10 transaction, if it's required. Therefore, you must NOT call the /sapapo/delete_lc_anchors program manually again using transaction LC10 after the liveCache has been initialized.
2)
For SAP liveCache documentation see the SAP note 767598 .
Before to run or recommend the liveCache initialization in LC10 please read the SAP note 640107 <!! > & the SAP document "Checklist for Initialization of SAP APO liveCache" at service.sap.com/scm -> Technology
-> Information on SCM 4.1 and prior releases
Information on SCM 4.1 and prior releases you will find here. < click on here > -> Backup and Recovery
3)
There are tables in the APO-database which contain references to liveCache-objects. The tables having references to liveCache-objects are called anchor-tables.
Thank you and best regards, Natalia Khlopina

What is Live Cache Anchor

Hi ,
Some times we see errors like "No Live Cache Anchor Found". Can somebody tell me in detail that what is a live cache anchor and why this inconsistency occurs. Is there a link containing detailed documentation?
Best Regards,
Chandan Dubey

Dear Chandan,
This error message "No Live Cache Anchor Found" states that for one or even for several characteristics combinations (see Transaction /SAPAPO/MC62) a so-called LiveCache anchor does not exist.In this case, a LiveCache anchor is a pointer to one or several time series in the LiveCache.
There is one LiveCache anchor per planning area, characteristics combination (planning object) and model (model belonging to the planning version, see transaction /SAPAPO/MVM). If for one planning area, time series objects were created for several versions with different models, that means several LiveCache anchors exist for the same planning area and for the same characteristics combination.If you created time series objects for several versions of the same model, that means one LiveCache anchor
points to several time series in the LiveCache.
If there is no LiveCache anchor for a planning area, a model and a characteristics combination, this also means that no respective time series exists in the LiveCache and thus, this characteristics combination cannot be used for the planning with this planning area for all versions of the model.If this state occured for a certain characteristics combination, the above-mentioned error message occurs if either exactly this characteristics combination is selected or if a selection contains this characteristics combination.
Possible causes and solutions:
- Time series objects have not yet been created for the selected version.
Solution: Create time series objects (see documentation)
- You are using a planning session with version assignment.For the version that was acutally selected, the time series objects were created, however, this is not the case for the assigned version.
Solution:Create time series objects for the assigned version.
- New characteristics combinations were created without the 'Create time series ob' option (see Transaction /SAPAPO/MC62).
Solution:Execute the report /SAPAPO/TS_LCM_PLOB_DELTA_SYNC for the basis planning object structure of the planning area.This will create the corresponding LiveCache anchors and LiveCache time series for all planning areas that used these basis planning object structure and for all versions of these planning areas for which time series objects already exist.
If none of these possible solutions is successful, you can use report /SAPAPO/TS_LCM_CONS_CHECK to determine and correct the inconsistencies for a planning area ('Repair' option).
I hope this helps.

Tibor

In which table is the Live cache data stored?

Hi experts,
I am new APO .Can anyone let me know in which database table will the Live cache data be stored?
Thanks in advance
regards
Ashwin.

Hello Ashwin,
the idea of the liveCache is to haev data permanently and quickly available without having to read/write from/to database. Therefore, the liveCache is <b>NOT</b> a physical database, it is a program in C++ that <i>simulates</i> a database and holds the data in the memory.
However, it does need so called liveCache-anchors which are saved on the database, and which are similar to pointers.
However, you can extract data from liveCache using BADIs or by creating a datasource on a planning area (for DP and SNP), manipulation can also be done only by BADIs or sophisticated programming (which basically uses RFCs).
I hope this answers your question.

Klaus

Unable to delete Order does not exist in live cache but in table POSMAPN

Hi Experts,
We are facing an issue where purchase order is not available in live cache (which means no GUID) but exists in database table POSMAPN. We have tried to delete it using standard SAP inconsistent order deletion program and also using BAPI BAPI_POSRVAPS_DELMULTI but not able to delete it.
Can anybody suggest a method by which we can get rid of this order from the system.
Thanks a lot.
Best Regards,
Chandan

Hi Chandan,
Apologize me for taking your question in a wrong perspective. If you want to delete the same then you need to Re-CIF the order from ECC so that it would come and sit in Live Cache. Once done, try using the BAPI.
If you are not successful with the above approach try running the consistency report /SAPAPO/SDRQCR21 in APO system
so that it first corrects the inconsistency between ECC and APO (Live Cache + DB tables) and then use the BAPI to delete the PO.
Not sure if you have tried this way. If this does not solve your purpose you need to check SAP Notes.
Thanks,
Babu Kilari

What is the significance of Live Cache in demand planning ?

Hi all,
Can anyone explain me significance of live cache in the demand planning. What are the issues will turn up for live cache if it is not properly maintained?
Thanks
Pooja

Hi Pooja,
SAP has come up with Live cache concept for storage and most important, quick and efficient processing of transactional data. Its a layer between data base and GUI and even the search methods and storage space has been optimized due to its structure. In DP it is used for storage of time series data whereas in SNP it can store both time series and order series data.
Regarding your second query, it is recommended to have Live cache consistency on a periodic basis for synchrinising data between LC and database tables. You can face many issues due to LC inconsistency as incorrect time series generation, Transactional data discrepancy, COM routine errors during background processing etc.
Let me know if it helps

BAPI to get the Quantity from orders in live cache.

Hi Folks,
Can any body provide me the BAPI to get the quantity value for the orders saved in the Live Cache. I tried using the BAPI
BAPI_SLSRVAPS_GETLIST2 ... but its not fetching any records for me. what else i need to provide it as input.
Thanks in advance.
Thanks & Regards,
Ramana

Check this thread.
Delete In-Transits.
In-Transit is not a particular order. Any Goods Movement from one location to another location will be considered as In-Transit.
Let's say Plant A is sending Product P1 to DC B against a Purchase Order.
In that case in plant A the stock will be reduced by the quauntity of goods being shipped.
At DC B, the Purchase Order will become In-Transit Stock.

Somnath

Thanks and regards,
Vaibhav

Hello Vaibhav,
while using transaction LC10, the error 11 "tp error: Terminating. [nlsui0.c ...]" occurs. The user authorization with tp fails and the application server cannot connect to the liveCache.
I assumed, that it's due to a library version mismatch, tp cannot use the liveCahe UNICODE libraries.
Please check, that the tp call at the command line works properly. And a dbmcli call in the transaction SM49 with the tp options
(dbmcli ::
-d <LC-SID> -n <LC-servername> -tpp <profile> -tpi <system-SID>
-tpc <connection - LCA/LDA> dbm_version)
works also properly.
I recommend you to update the liveCache client software on the Application server.
If you've got access to OSS/Service Market Place, then please take a look at note
649814 how to update the liveCache client software on the application server.
< Please also review the SAP notes 847736 & 831108 >
Before the liveCache client version will be upgraded on the application
server you can use the workaround by switching off the central authorization for the liveCache LCA/LDA connections:
In transaction LC10, choose Integration and deactivate the option Central authorization, then save.
If you are the official SAP customer, I recommend you to create the ticket to SAP on 'BC-DB-LVC' queue.

Data fetch from live cache

How can I retrieve data from live cache?This is in Demand Planning : SCM APO.
Please suggest ways.
Thanks & Regards,
Savitha

Hi,
some time ago I worked on SAP APO.
To read live cache, you first have to open a SIM session.
You can do this as shown in this function module:
FUNCTION ZS_SIMSESSION_GET.
*"*"Local Interface:
*" IMPORTING
*"     REFERENCE(IV_SIMID) TYPE /SAPAPO/VRSIOID
*" EXPORTING
*"     REFERENCE(EV_SIMSESSION) TYPE /SAPAPO/OM_SIMSESSION
CONSTANTS:
lc_simsession_new       TYPE c LENGTH 1 VALUE 'N'.
DATA:
lt_rc                   TYPE /sapapo/om_lc_rc_tab,
lv_simsession           LIKE ev_simsession.
IF NOT ev_simsession IS INITIAL.
    EXIT.
ENDIF.
*--> create Simsession
CALL FUNCTION 'GUID_CREATE'
    IMPORTING
      ev_guid_22 = lv_simsession.
*--> create transactional simulation
CALL FUNCTION '/SAPAPO/TSIM_SIMULATION_CONTRL'
    EXPORTING
      iv_simversion            = iv_simid
      iv_simsession            = lv_simsession
      iv_simsession_method     = lc_simsession_new
      iv_perform_commit        = space
    IMPORTING
      et_rc                    = lt_rc
    EXCEPTIONS
      lc_connect_failed        = 1
      lc_com_error             = 2
      lc_appl_error            = 3
      multi_tasim_registration = 4.
IF sy-subrc > 0.
    CLEAR ev_simsession.
*   error can be found in lt_rc
ENDIF.
* return simsession
ev_simsession = lv_simsession.
ENDFUNCTION.
Then you can access the live cache.
In this case we read an order (if I rememver correctly, it's a plan order):
DATA:
lv_vrsioid                  TYPE /sapapo/vrsioid,
lv_simsession           TYPE /sapapo/om_simsession.
* Get vrsioid
CALL FUNCTION '/SAPAPO/DM_VRSIOEX_GET_VRSIOID'
    EXPORTING
      i_vrsioex_fld = '000' "By default
    IMPORTING
      e_vrsioid_fld = lv_vrsioid
    EXCEPTIONS
      not_found     = 1
      OTHERS        = 2.
CALL FUNCTION 'ZS_SIMSESSION_GET'
      EXPORTING
        iv_simid      = iv_vrsioid
      IMPORTING
        ev_simsession = lv_simsession.
CALL FUNCTION '/SAPAPO/RRP_LC_ORDER_GET_DATA'
    EXPORTING
      iv_order      = iv_orderid
      iv_simversion = iv_vrsioid
    IMPORTING
      et_outputs    = lt_outputs
      et_inputs     = lt_inputs.
If you change something in your simsession, you have to merge it back afterwards, so that your changes become effective.
You can do this like that:
* Merge simulation version (to commit order changes)
CALL FUNCTION '/SAPAPO/TSIM_SIMULATION_CONTRL'
    EXPORTING
      iv_simversion                = lv_vrsioid
      iv_simsession                = lv_simsession
      iv_simsession_method         = 'M'
    EXCEPTIONS
      lc_connect_failed            = 1
      lc_com_error                 = 2
      lc_appl_error                = 3
      multi_tasim_registration     = 4
      target_deleted_saveas_failed = 5
      OTHERS                       = 6.
I hope this helps...

Data storage in Live Cache

Hi,
Can some1 explain me how the SNP data is stored in the live cache.
I know it's by series of order. But tell me is there any mapping involved in it?
Thanks,
Siva.

Order series data is used by both SNP and PPDS.
While I do not know the exact way data is stored in liveCache the following helps me to explain and understand.
Each record in liveCache for Order Series data is stored as
Location Product combination-ATP Category-Quantity-Time Stamp.
Unlike Timeseries data CVC is replaced by a location product combination only, keyfigure is replaced by ATP Category (each kind of Order elements has its own ATP Category) and Time Bucket is replaced by actual Time Stamp (in UTC ddmmyyyyhhmmss format).
The mapping is essentially with ATP Category which maps to corresponding MRP elements in ECC or R/3.
In the SNP Planning Area for each keyfigure the Category Group defines the grouping of ATP Categories for which orderseries data will be displayed in that particular keyfigure.
Hope this helps.
Thanks,
Somnath

How to see Live cache order number in planning book of APO ?

Unable to login to Live Cache

Hi,
I've just completed an SCM 2007 Installation alongwith the live cache.
However, when I try to login to the LC using the dbmcli command (user control/superdba & the pwds. set during installation), it gives the foll. error:

Also, I'm not able to use LC10-->Live Cache Monitoring
Pls help, since it's extremely urgent.
Thanks a lot,

Hello Saba,
-> For SAP liveCache documentation in English see the SAP note 767598.

Some concern about Live cache Homogeneous System copy

Hi All,
I need to do the Homogeneous system copy SCM 5.0 / Live cache 7.6.00 on AIX. Following are the Source and target System SID for Live cache. Moreover I had check the respective SAP note 457425 and 877203 but still having some concern.
Source System
Live cache SID           =      SCD
Live cache user ID      =      SAPSCD
Live Database instant software owner = scdadm
Live cache Data Size      = 8 GB ( 4 Data volume / 2 GB each / auto extend off)
Target System
Live cache SID           =      SCT
Live cache user ID      =      SAPSCT
Live Database instant software owner = sctadm
Live cache Data Size      = 4 GB ( 2 Data volume / 2 GB each / auto extend off)
For same I having following concern.
1.     Since there is difference between source system and target system size / data volume number what action I need to take on target system. Do I need to add two more data volume into the target system?
2.     After complication of database restore on target the system do I need to change the Live cache user ID (i.e. SAPSCD to SAPSCT)?
or
It is just fine to change the log on data in Integration tab in LC10.
Please let me know some more information on same.
Thanks,
Harshal

Hello Harshal,
"1. Since there is difference between source system and target system size / data volume number what action I need to take on target system. Do I need to add two more data volume into the target system?"
Please pay attention to the SAP note :: 457425    Homogenous liveCache copy using backup/restore
Please update the thread withy additional information ::
What is the version of the source liveCache? What is the version of the target liveCache?
How much data do you have in the source liveCache?
And you need to have the size data area of the target liveCache to be able to restore the databackup created in the source liveCache.
So by the size of the data volumes in the source liveCache, it's not clear how much data you have.
"2. After complication of database restore on target the system do I need to change the Live cache user ID (i.e. SAPSCD to SAPSCT)?"
Please review the SAP note 877203.
You could rename the user SAPSCD to SAPSCT using the SAP note 877203 steps
OR
You could have the user SAPSCD in the target liveCache as Standard liveCache user &
After you run the homogenous liveCache copy using backup/restore procedure you need
to change the LCA/LDA/LEA connection with user SAPSCD on target system and
set the user SAPSCD to the user containers ( please see the SAP note 616555 for more details )
Before to restart the liveCache in LC10.
PS: Please pay attention about the value of the liveCache parameter _UNICODE.
      What are the values of this parameter in the source & target liveCache?
Thank you and best regards, Natalia Khlopina

Data written to Live cache but not visible in SNP Planning Book

Hello All,
We have an issue this morning, Customer service cordinator placed a Purchase Order in SNP (VMI). Order was sent to ECC and a sales order was created. This morning when we check the sales order, it shows 4574 cases but in TLB Pur chase order, it only some 2000 something. I went to OM16 and checked the sales order and it had the entire 4574 cases written in the live cache. Any help on how to get the entire quantity to be seen is appreciated. Thank you.

Rohit.

Hi Ada,
Thanks for the reply. The issue got resolved by itself.
