Function Module to Fetch data of Vendor for Inbound Delivery at runtime

Hi All,
I am new to EWM. I am using BADI /SCWM/EX_DLV_DET_PROCTYPE method CHANGE_PROCTYPE to change process type of the inbound delivery as per some logic from a custom table. However the parameter Vendor is not available in IS_ITEM during inbound delivery creation. Vendor is one of the key fields in my table.
Does anyone know any solution/function modules to fetch vendor data for the inbound delivery at runtime. I know the database tables to fetch vendor but this works only once the inbound delivery is saved.
Thanks and Regards,
Vanessa Noronha

When fetching data using VIEW in source system it works fine.
When testing for fetching data of SFLIGHT using function module ZRSAX_BIW_GET_DATA_SIMPLE
made a copy of RSAX_BIW_GET_DATA_SIMPLE, it is working fine.
Pls suggest the cause of error.

Generic datasource by function module to fetch data from multiple tables?

I'm writing a function module to fetch price, for generic datasource.
At first, extract test is OK. But InfoPackage never stop when loading data to PSA in BW.
And I find the example codes:
     OPEN CURSOR WITH HOLD S_CURSOR FOR
      SELECT (S_S_IF-T_FIELDS) FROM SFLIGHT
                               WHERE CARRID IN L_R_CARRID AND
                                     CONNID IN L_R_CONNID.
    ENDIF.                             "First data package ?
* Fetch records into interface table.
*   named E_T_'Name of extract structure'.
    FETCH NEXT CURSOR S_CURSOR
               APPENDING CORRESPONDING FIELDS
               OF TABLE E_T_DATA
               PACKAGE SIZE S_S_IF-MAXSIZE.
    IF SY-SUBRC <> 0.
      CLOSE CURSOR S_CURSOR.
      RAISE NO_MORE_DATA.
    ENDIF.
    S_COUNTER_DATAPAKID = S_COUNTER_DATAPAKID + 1.
ENDIF.
There using Cursor to fetch data package by package, and raise exception NO_MORE_DATA to stop the loading process.
Now I fetch data from multiple tables, I don't think I can use Cursor.
Then How can I handle this?
Thanks a lot.

Thanks

Not able to fetch the data by Virtual Cube

Hi Experts,
My requirement is I need to fetch the data from Source System (From Data base table) by using Virtual Cube.
What I have done is I have created Virtual Cube and created corresponding Function Module in Source System.
That Function MOdule is working fine, if Data base table is small in Source System.But If data base table contains huge amount of data (millions of record), I am not able to fetch the data.
Below is the code I have incorporated in my function module.
c_th_mapping TYPE CL_RSDRV_EXTERNAL_IPROV_SRV=>TN_TH_IOBJ_FLD_MAPPING.
DATA:
    l_s_map TYPE CL_RSDRV_EXTERNAL_IPROV_SRV=>TN_S_IOBJ_FLD_MAPPING.
l_s_map-iobjnm = '0PARTNER'.
l_s_map-fldnm = 'PARTNER'.
insert l_s_map into table l_th_mapping.
create object l_r_srv
    exporting
       i_tablnm              = '/SAPSLL/V_BLBP'

In the above function Module,Internal table L_TH_MAPPING contains Info Objects from Virtual Cube and corresponding field from Underlying data base table.
The problem where I am facing is, in the method FETCH_PACK_DATA, initially program is trying to fetch all the recordsfrom data base table to internal table.If Data base table so lagre, this logic is not working.
So would you please help me how to handle these kind of issues.

Hi Experts,
My requirement is I need to fetch the data from Source System (From Data base table) by using Virtual Cube.
What I have done is I have created Virtual Cube and created corresponding Function Module in Source System.
That Function MOdule is working fine, if Data base table is small in Source System.But If data base table contains huge amount of data (millions of record), I am not able to fetch the data.
Below is the code I have incorporated in my function module.
c_th_mapping TYPE CL_RSDRV_EXTERNAL_IPROV_SRV=>TN_TH_IOBJ_FLD_MAPPING.
DATA:
    l_s_map TYPE CL_RSDRV_EXTERNAL_IPROV_SRV=>TN_S_IOBJ_FLD_MAPPING.
l_s_map-iobjnm = '0PARTNER'.
l_s_map-fldnm = 'PARTNER'.
insert l_s_map into table l_th_mapping.
create object l_r_srv
    exporting
       i_tablnm              = '/SAPSLL/V_BLBP'
      i_th_iobj_fld_mapping = l_th_mapping.
l_r_srv->open_cursor(
    i_t_characteristics = characteristics[]
    i_t_keyfigures      = keyfigures[]
    i_t_selection       = selection[] ).
   l_r_srv->fetch_pack_data(
    importing
      e_t_data = data[] ).
return-type = 'S'.
In the above function Module,Internal table L_TH_MAPPING contains Info Objects from Virtual Cube and corresponding field from Underlying data base table.
The problem where I am facing is, in the method FETCH_PACK_DATA, initially program is trying to fetch all the recordsfrom data base table to internal table.If Data base table so lagre, this logic is not working.

RFC is to be created in ECC that should fetch the data from CRM

Hi Gurus,
I am facing with a problem in knowing the fields and table to develop an RFC in ABAP.
My exact requirement is :
ABAP : the field PERNR is passed as exporting parameter to RFC and imporitng paramter is an internal table that consists of   PERNR and overpayment status field.
         ABAP                                                                             CRM
Exporting Parameter = PERNR                                  Importing Parameter= ? " Which field should i take as importing field"
Importing Parameter = LT_ITAB                                Exporting Parameter= ? " internal table consisting input field and
overpayment status field "
NOTE : In order to provide a means of progressing overpayments and to provide a statistical analysis of overpayments, RFC is required that combines the information in CRM with that in ECC6 for overpayment details.
Pls Can u Help me by providing table and field name in CRM
Thanks,
Reddy..

Hi Kalpana,
if you want to fetch ecc data to crm you have to create one rfc enabled function module in ecc use that function module in crm.
calling a smart form is different scenario go through this links you can get to know how to call..
**************** - Calling an RFC function module from one system to another
Print an Adobe Form from CRM Web UI - CRM - SCN Wiki
Call a Smartform in webUi
example:
sample code:
clear lv_client.
IF sy-mandt = '110'.
     CONCATENATE 'ECDCLNT' sy-mandt INTO lv_client.
   ELSEIF sy-mandt = '200'.
     CONCATENATE 'ECQCLNT' sy-mandt INTO lv_client.
   ELSEIF sy-mandt = '300'.
     CONCATENATE 'ECPCLNT' sy-mandt INTO lv_client.
endif.
call function 'zfunction_module' destination lv_client
exporting
is_date = lv_date
tables
ot_tab = ot_tab.
Thanks & Regards,

How can i join the header and item table to fetch the data

hi experts,
i have a doubt in using inner join or for all entries, for fetching the data from the item table mseg, by taking the doc.no from mkpf. Plz sort out the difference, what happens, if i use the both statements for fetching data

Hi,
Both has same functionality.
but if u are using FAE, u ahev to check for the
~intial condition of the source table,
~ duplicate entries, if any
Inner join will fetch the data from all the join tables at once. FAE will fetch the date from a table first then use that data to fetch data from subsequent table.
say in ur case, if u r using FAE,
1.select from mkpf.
2.select from mseg fae in I_MKPF.
first try using JOIN. if it is taking lots of time, then try FAE.

madhu

Function module for access OM Data from infotype 1001

We had a function module for accessing OM data viz. Infotype 1001. Could you let me know.
Advanced thanks,
Dasaradh kosana

Hi Dasaradh,
Do you want the fm which fetches the data from HRP1001 , if this is the case you can use this FM RH_READ_INFTY_1001.
Reward Points if it is helpful

How does Fetch Rx Data works?

Dear Sir or Madam,
I have a problem when I am implementing MAC protocols by using LabVIEW and USRP2. Actually there are two problem, I will show them in a simple CSMA protocol.
The first design is that in CSMA protocol, node 1 sent a data packet to node 2, and node 2 received the packet, analyzed it, and sent back a corresponding ACK. The problem is, node 2 need to switch between receiving mode (to receive the packet) and transmitting mode (to sent ACK back), and the switching time is non-neglectable (around 7 to 10 ms). That delay significantly decreases system performance. Is that any way to reduce the switching time?
The second problem is rising after the first one. To overcome the time delay, I use two antennas in the system, therefore one can always work in Tx mode and another in Rx mode therefore no switching is needed. The block diagram is simplified as figure (if transmitter mode is set to false, then the receiving VI works by using another antenna).
The problem is, since we are using if structure, there is noway that transmitting and receiving can work concurrently. However, nodes always receive the signal it sent in the last while loop round. For example, after receiving a DATA packet from another node, this node sends a ACK back, and then the transmitter mode are switching to false then I can receive next packet. However, after sending the ACK, and switching to reception mode, I can receive the ACK I sent myself! That is my question, how does fetch Rx Data VI works?
Thank you very much!

Hi HustLiliAn,
Thank you very much for you quick reply. I have to say sorry that my code is only partially belonging to me so I cannot distribute all of them, beg your understanding
To overcome the delay, I open both Tx and Rx session at the beginning of the code so I don't need to initial and abort session before and after using respectively. It could save a lot of time (I measure the same delay as you shown). I read from WBX application notes (http://files.ettus.com/uhd_docs/manual/html/dboards.html) that if the system is working in the duplex mode, then antenna TX/RX is using for transmission and RX2 is using for reception. I simply tested it and it seems true.
Since two antennas are working concurrently, the receiving antenna (RX2) can receive packet even it is sent by TX/RX. My problem is, in software level I have used the if structure to make transmission and reception work successively, RX2 can still receive signal sent by TX/RX. That is the real problem. Probably we can write some compensation VI which we can remove it by using the transmitted signal, but I still want to know is there any official solution for it.
BTW, I use the modulation toolkit. Its demodulation VI is also quite slow.
Thank you for your reading. I am not a native English speaker, so if my post make you confuse, please let me know and I would like to elaborate it again.

Fetch Personalization data in SU01

Hello,
In SU01 transaction, there is a new tab added called PERSONALIZATION Tab. Now for personalization Object key LAW_PERS, we are storing personalization data.
I want to fetch this data. How do I do it ? Is there some database table or is there some function module that I can use in my code to fetch these personalization data ?
Regards,
Rajesh.

Rajesh,
You have 239 unresolved questions... did no one ever in all of those questions you have not followed up on show you the magic button which reveals almost all information about the system which you would ever need?
