Recording thunder in the field

hello all:
we recently have had a spate of thunder storms and i had the bright idea to setup my MacBook, STP, and my m-audio Firewire Solo with an instrument mic to try and capture some of the thunder claps. i had the mic pointed out of an open window.
the only problems i had were the fact that the truly loudest claps were causing the FW Solo to clip. i got to a point where i could guage the sound levels just after the lightning flash based on the brightness, duration, and perceived closeness and adjust the gain quickly. playback revealed that the claps that clipped sounded not-so-great. i haven't spent much time working with the ones that didn't clip, but i think i can EQ and compress them to get something that sounds pretty good.
my question is, doe anyone know of any good resources for field recordings like this? does anyone have any recommendations for mics or other setup suggestions? i don't have any reason for doing it other than academic curiosity.
PowerMac G5 2.5GHz Mac OS X (10.4.5)

you need to use a hardware based compressor... and turn down the gain. there is not a compressor in the world that give you that type of gain reduction and still sound natural. i would even consider recording to analog tape and then capturing. clipping a digital input is nasty, where clipping an analog tape is, albeit bad sounding, it won't give you the digital clipping artifact. i'm going to go ahead and make the assumption that "distorted peak thunder" has no discernable difference in sound that "clean peak thunder", so when it clips on tape, it won't affect your sound... it will give you just a bit more headroom.
i would also use 2 mics. use 1 small diaphram condensor and then use a large diaphram condensor. in the mix, combine the 2... using low freqs from the large diaphram mic.

Hi ,
I have a scenario like below.
name   id     emailid
X        1      XXX
y        2      XXX
z        3     YYY
w       4      XXX
So I want to send mail to XXX with X y and W information at a time i.e means in the single mail and mail should go to YYY with the Z information.
please guide me on this.
Thanks & Regards,
Suresh.

Hi ,
Sort on itab mailid.
lv_mail = space.
loop at itab into wa.
if lv_mail ne wa-mail.
lv_mail = wa-mail.
endif.
if lv_mail = wa-mail.
read itab2 with mail = wa-mail.
if sy-subrc eq zero.
concatenate itab2-msg wa-masg into itab2-msg.
modify itab2 at sy-tabix transporting msg.
else.
itab2-mail = wa-mail.
itab2-msg= wa-msg.
append itab2.
endif.
endif.
endloop.
loop on itab2.
send mail.
endloop.
in some scenario we faced problem with using "at end".
i am not sure exactly, think basis on type and key part of internal table.so the above is an suggestion from my side.

Vendor Master Record: Tax Number 1 Field

Hi Everyone,
For some reason, when you enter XK01 or XK02 for creation or change of vendor master record, Tax Number 1 within the Control Tab is visible and able to be input. However, when displaying the vendor master record through XK03, the field is not visible. Reviewing the field options for vendor master record did not reveal anything to me. Any ideas why?
Thanks,
Pete

How can we get record numbers for the rows after grouping them?

Post Author: preethibaddam
CA Forum: Formula
hii everyone,
i want to number those records which are grouped by a column.
eg: if i group the emp table with the deptno then the records for the deptno10 group should start from 1 and end with an N number and again when it shifted to deptno20 group than the records for that deptno20 should again start with 1 and end with N number.
i tried placing record number from the field explorer but it is not working. the other group records start with the ended number from the first group.
thanks

Record number from CR will count all the records. You could use a running total, and reset on change of group.

Records are not getting imported due to new line charactor in the field

Dear All,
I am trying to load a file into target but the import is failing. The error thrown is as below;
During the import of leads into CRMoD through loading the New lead/Step lead file received from CA, leads have not been imported and we encountered the following
error message:
"Import field 'LAST_NAME' had a blank value for the required Oracle CRM On Demand field 'Last Name'. This record was not imported. Please enter desired values for
the required fields and re-import this record."
Reason:
Leads are not imported due to an additional new line (Enter) character, which results in the subsequent lines not being picked up and the error of import failure.
Please help me to resolve this to remove the new line charactor in the field so that import succeeds..
By the way, I am working on ODI 11g.
Thanks in Advance
Regards
Santy

While i was reading your post i remembered an issue that madded me. I don't know Oracle CRM, but a possible workaround could be to create a temporary Oracle table and load all data inside it. After that load in CRM only valid rows.

How can i post the fields in the screen by selecting a record

Hi,
I have a problem in dialog programming.
I need to populate the fields in the screen by selecting a single record.
For example,
    Screen consists of 'CARRID, CONNID,FLDATE... fields.
    By pressing F4 in CARRID field it will display the contents from database table and display the records. If i select the record LH 0400 ... record then automatically the connid field should fill with the contents of the record i.e., 0400 and similarly the remaining fields.
   How can i do this in dialog programming?
   I tried with F4IF_INT_table_.. function module. There is a table parameter DYNmapping. But dont know how to use it? Can any body explain me how to use it?
   Thanks in advance..
   Suvan

Hi Vinod,
Thanks for your reply. I solved my problem. It is working with the table parameter 'DYNPFLD_MAPPING' in the function module 'F4IF_INT_TABLE_VALUE_REQUEST'.
With your logic we can't decide which record is selected. Because there can be multiple records for a single CARRID.
My question is how to post the entire record into the screen fields at a time? It is possible with the parameter I specified inthe above said function module.
With dictionary reference it will fetch the entire entries from the Check table.
Thanks again for your co-operation.

How to change the field sequence in Customer master record.

Dear Friends,
We are required to chage the sequence of customer master record fields that are available under different tabs of 'General Data', 'Company Code Data' and Sales Area Data.
Our client requirement is to place all mandatory fields in the first screen of customer master record. Here the intention is to save the user time instead going and clicking multiple tabs/screens to fill information on only one or two tabs. Please suggest us the availabe solution in SAP for this requirement.
Thank you
Raghu Ram.

Hi
Step 1: Take help of a FI guy and:
The fields can be suppressed by configuring through Financial accounting > Business Partners > Customers > Account groups.
Step2 : The challenge inyou project is to have a single tab with the allowed fields
A technical guy can only help you out on this . Again This would be a huge effort since first you need to change the code for customer master. As customer master is a source of data for various documents in SD , at each place you will have to do changes in th code...I don't think it is feasible.
Instead of doing this , create an external interface for transferring the value to SAP through BAPI. this would involve integration and may be as per defined SAP standards you can use CSV files or XML files for the integration process.
This would be a better option than fiddling with SAP system

LSMW Recording.. Cannot see the fields when going to Field mapping step

Hi all,
I am going a test loading of data with the LSMW and I am doing with a recording. The transaction I have used is related to my company.
When I go to the field mappings step I dont see the field for the target structure with which I can map the source fields..
What may be the problem. Let me know.. If my question is solved, I will award appropirate points.
Thanks,
-Ken

Hi Consu,
Please see, when your recording is over.. it is displayed right?
The moment it is displayed, there on same screen either click on 'DEFAULT ALL " button on application toolbar or go to menu path edit--> default all.when u create recording u can click on this button but when it is assigned to your project , this option become disabled , so crate a new recording and follow above steps.
Best of luck
Thanks,
Billy

No record found in the table while using condition for the new added field

Please suggest. Thanks in Advance.

Can the fields of DS be written as record entries in an infocube?

Hi all,
Can the fields of the datasource be copied as values into an infocube. for eg. my DS has the structure A,B,C,D.
and i want these to be written as
A
B
C
D
i,e each record in the DS should now be written as 4 records in the infocube.
is this possible?
Regards
Sujai

Hi Sunil,
I think you got me wrong. I'l explain the scenario.
I have a Z table in R/3 that has the monthly targets for teh fiscal year specfied in columns i.e there are 12 fields, 1 or each month.
R/3 structure is like this
Jan_target quan 13 3
feb_target quan 13 3
mar_target quan 13 3
but in my report i have a column that has field called "monthly target". the month is an input ready variable. so when the user gives the input month i have to print the target value for that particular month that is stored in the the R/3 table.
I cannot change the infoobject to which the fields of the DS is mapped dynamically in my report, hence i thought of maintaining an infocube with a field calmonth and another KF for targets and populating these infoobjects accordingly.. like, if DS field is "jan_target" then calmonth = 012007 KF_target = ####
if DS field is "feb_target" .. calmonth = 022007 KF_target = ####... etc.
the R/3 table doesnt have any field for the fiscal year as well. the fisc year is calculated from the current month and year, and the targets are maintained for only 1 year in teh R/3 table.
so for each record in the DS i must write 12 records into my cube i.e calmonth 01 to 12 and their respective targets.
How do i do this??

How to store records that are entered in the fields?

Hi friends can any one help me how to store the records that are given as input.
Say if Empid - 123456, this 123456 has to be stored in table it will be stored but can any one help me with procedure?
Thanks

Hi,
If the records are from an input file, you will have to first create a structure for the Employee id ....
then, read the input file data into the internal table you have defined in the earlier step...
then, loop at the records one after the other and update the records directly into the table....( typically this is a direct update of data and will be done when you were dealing with the data relating to a "Z" table )
please follow the procedure and let me know how it worked for you or if you are still having issues on this.
Thanks,
Vishnu.

Whether the fields of a single row in an internal table has got value.

I am doing an archiving report in PS Module.
The table RPSCO has 12 fields which represent each month.The records in the table are based on OBJNR and YEAR
Now i need to check for the latest year which month has some value .If any of the month has got some value i need to take that month.
Sample table given below.
OBJNR           year    Month1    month2      month3    so on
1)PR00002409 2006     0.00     0.00     664.70-     0.00 0.00     0.00     0.00     0.00     0.00
0.00     0.00     0.00     0.00
2)PR00002409 2005     0.00     0.00     0.00     0.00     0.00     0.00     0.00 0.00     0.00     0.00     48.70     127.20     0.00
In this case the output should be Month3.Because the latest year is 2006 and Month is Month3.

Hi Susmita,
You have to use DO VARYING option from field 3 onwards.
Below is the sample program to check whether the field has a value or not.
tables: rpsco.
data: it_rpsco like rpsco occurs 0 with header line.
data: v_wlp type rpsco-wlp00,
      v_wtp type rpsco-wtp00,
      v_pos type i.
select * from rpsco into table it_rpsco where gjahr = '2007'.
if lines( it_rpsco ) gt 0.
loop at it_rpsco.
clear v_pos.
do 16 times varying v_wlp from it_rpsco-wlp00 next it_rpsco-wlp01
              varying v_wtp from it_rpsco-wtp00 next it_rpsco-wtp01.
   v_pos = v_pos + 1.
   if not v_wlp is initial.
     write:/5 v_pos , 35 v_wlp, 70 v_wtp.
     exit.
   endif.
enddo.
endloop.
endif.

Problem with READ Statement in the field routine of the Transformation

Hi,
I have problem with read statement with binary search in the field routine of the transformation.
read statement is working well when i was checked in the debugging mode, it's not working properly for the bulk load in the background. below are the steps i have implemented in my requirement.
1. I selected the record from the lookuo DSO into one internal table for all entried in source_packeage.
2.i have read same internal table in the field routine for each source_package entry and i am setting the flag for that field .
Code in the start routine
select source accno end_dt acctp from zcam_o11
into table it_zcam
for all entries in source_package
where source = source_package-source
     and accno = source_package-accno.
if sy-subrc = 0.
delete it_zcam where acctp <> 3.
delete it_zcam where end_dt initial.
sort it_zcam by surce accno.
endif.
field routine code:
read table it_zcam with key source = source_package-source
                                             accno = source_package-accno
                                             binary search
                                             transportin no fields.
if sy-subrc = 0.
RESULT = 'Y'.
else.
RESULT = 'N'.
endif.
this piece of code exist in the other model there its working fine.when comes to my code it's not working properly, but when i debug the transformation it's working fine for those accno.
the problem is when i do full load the code is not working properly and populating the wrong value in the RESULT field.
this field i am using in the report filter.
please let me know if anybody has the soluton or reason for this strage behaviour.
thanks,
Rahim.

i suppose the below is not the actual code. active table of dso would be /bic/azcam_o1100...
1. is the key of zcam_o11 source and accno ?
2. you need to get the sortout of if endif (see code below)
select source accno end_dt acctp from zcam_o11
into table it_zcam
for all entries in source_package
where source = source_package-source
and accno = source_package-accno.
if sy-subrc = 0.
delete it_zcam where acctp 3.
delete it_zcam where end_dt initial.
endif.
sort it_zcam by surce accno.
field routine code:
read table it_zcam with key source = source_package-source
accno = source_package-accno
binary search
transportin no fields.
if sy-subrc = 0.
RESULT = 'Y'.
else.
RESULT = 'N'.
endif.
