Live Cache activation

Hi,
In my PC..every time i am manually activating Live Cache in LC10.is it possible for automatic actvation during server restart. where i have to make settings for automatic live cache activation.
Regards
Arasu

Hi Arasu,
Automatic activation, let me explore it and check any such
option is there or not like.
Some of the few consequences of automatic activation will be
1) Dependency of jobs start/end during livecache activation
2) Clearance of inbound/outbound queues
3) User lock/unlock
4) Livecache consistency check
All these needs to be taken care during restart of livecache.
Hence manual is always be preferred.
Please confirm whether your query is resolved.

Sales ORDER- live cache problem- HIgh

Hello Experts,
Please advise me how to fix the error message which occurs while creating sakes order.
Error message reads:
" ATP check in System PA1CLNT410 is not possible since
livecache is not active".
Kindly advise

In SAP Best Practice, I found this note which I thought would be helpful to you.
Check Planning Version 000
In your SAP SCM system, use the following path:
SAP Menu --> Advanced Planning and Optimization --> Master Data --> Planning Version Management --> Model and Version Management
Make sure that the planning version 000 u2013 Active Version is available.
If this planning version is not available, this means that the LiveCache has not been initialized. Proceed with the LiveCache initialization before you start with the installation of any SAP Best Practices scenario.
*Live Cache*
LiveCache version:     KERNEL     7.5.0   Build 015-122-076-685
DBM server version:      DBMServer 7.5.0   Build 015-122-076-685
Operating system:     SunOS
So what you have to do is that check with your basis people to instal LiveCache

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.
Thanks,
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.
Thank you and best regards, Natalia Khlopina

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 ?

I am trying to see the Live cache order number in Planning book by entering getio as T-code while in planning book.
By this I am not able to see the LC details. Can anyone help me out on the same?

Dear Rahul!
Are you using correctly the transaction GT_IO? As per your first reply you are using GETIO.
Try GT_IO!

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:
-24950,ERR_USRFAIL: User Authorization failed.
Also, I'm not able to use LC10-->Live Cache Monitoring
Pls help, since it's extremely urgent.
Thanks a lot,
Saba.

Hello Saba,
-> For SAP liveCache documentation in English see the SAP note 767598.
-> In general, the error could be due the wrong password of the dbm user.
     For example, I created the database instance NLK with the control user and
    control password. If I will try to connect to the database with wrong password
    I will get this error ::
                                 dbmcli -d NLK -u control,test
                                 Error! Connection failed to node (local) for database NLK:
                                 -24950,ERR_USRFAIL: User authorization failed
-> You are running SCM 2007 < SCM 5.1 > system, therefore you are SAP customer.
    Please create the SAP ticket concerning this issue => we could logon via OSS and check the status of your system.
    Please set 'high' priority of the ticket, if it's extremely urgent.
    If it's the DEMO or PROD system you could escalate the message to 'VH'.

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.
Regards,
Klaus

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
