What are disadvantages by using field catalogmerge in ALV

can any body tell the disadvantages by using field catalogmegre and maximun how many fields build the filed catalog.

Hi Diva,
I have gone thru the advantages... and don't see and disadvantage in building it thru functions....
The only advantage, that you can maintain dynamically during runtime, the structure of your ALV grid.
Mostly you are using static structures for ALV, so it is easier to create a static structure in SE11 and give this structure to your ALV_GRID_DISPLAY as a parameter.

for knowing tax declaration or tax caluculation in indian payroll , it is not dependent on only couple of wage types or infotypes it is dependent on lot of other wage types and infotypes
fro IT 580 to IT591
and for other information check the documentation of function INTAX in PE04 tcode
you should also know the wage types that caluculates tax

What are the 3-bit field choices for Hw_Arm_Sel in PCI-6601

Hi,
I am programming our own driver to operate the PCI-6601. For our application we need hardware arm option. I know it is possible to use 2 counters for that, but NI-TIO should support also hw_arm. Although it is not explained in the registry document at all, after some tedious check in the DDK examples I found that this bits are located in the Gi counting mode register. I know the position of the HW_enable as well as the position of the 3 bits for pin sellect options. What I do not know is What are the 3-bit field choices for Hw_Arm_Sel . I contacted NI support but got no support. How can NI sell boards and when a customer who is not using LAbview or Measurement Studio or DDK, but is implementing his own driver is then so arrogantly turned down from NI? Also, how can NI publish just part of the registers the board support, and when a customer contacs and asks for some registers get not at all support? I can not foretell the missing registers, and it is pretty unprofessional to document just partly the registers of 660x devices. And on request you got nothing.
I hope someone from the community know about this Hw_Arm_Sel 3 pin options. Otherwise, there is just an option of error and trial. Or simply throw the board in the garbage.

Hi Kirco,
I have some more information for you :-)
I haven't been able to speak to the developer who is the most familiar with TIO programming since he's out of the office, but I have come across his notes from when he was writing support for the DAQmx driver.
As I described earlier, the HW_Arm_Sel bits don't select a connector I/O pin, but an internal trigger signal. There are seven internal trigger lines, and the HW_Arm_Sel bits map directly to the internal trigger signal: 0b000 - 0b111 map to 0d0 - 0d7. In order to route an I/O pin to an internal trigger, you must also write to a few more registers.
From what I've read, there are two more register families that need to be programmed: TG_x_LevelEdgeReg and TG_x_CombinationReg, where x is the internal trigger number. In your case, you only need one pin from the I/O connector to be your arm start trigger, so TG_0_LevelEdgeReg and TB_0_CombinationReg will suffice for your application.
TB_0_LevelEdgeReg :: Offset 0x660
TG_0_LevelEdgeReg is only 8 bits wide, and maps as follows:
7..6: EdgeMode
5..0: LESel
LESel selects the I/O connector pin to use as the source for the internal trigger signal. 0d0 - 0d39 will select the I/O pin of the same number. NB: behavior for TG_x_LevelEdgeReg is more limited for triggers 1-7, and only a small subset of the I/O pins can be selected for those trigger signals. Trigger 0 can use any I/O pin. Setting these bits to 0d63 forces the trigger source low, and can be used as a way to 'unroute' it when you're finished with your program.
EdgeMode determines whether the TIO will detect an edge of the incoming signal, or just pass the signal level straight through. When detecting edges, it will latch the signal and generate a single TIMEBASE3 pulse instead. 0b00 sets level mode; 0b01 sets rising edge; 0b10 sets falling edge; 0b11 sets either edge.
TG_0_CombinationReg :: Offset 0x6A0
TG_0_CombinationReg is 32 bits wide, and has three fields of interest:
19..16: CombFunction
5..4: CombTypeB
1..0: CombTypeA
CombTypeA controls which trigger subsystem to use as the source for the trigger signal. Since you're coming from an I/O pin and using the edge/level subsystem, you must set these bits to 0b01.
CombTypeB is similar to CombTypeA, and although you won't be using trigger B, set it to 0b01 to be safe.
CombFunction performs a simple logic function on A and B. Since you're only using a single I/O connector, you only need the A output, so set these bits to 0b1100.
All of the other bits should be set to 0b0.
Unfortunately, I'm unable to test these statements since my test machine is currently being used for another research project. Please let me know what happens if you decide to test.

If we open a transaction i need to find what are the tables used

hi gurus
can anyone suggest me
if we open a transaction liek va01
i need to find what are the tables used
what are the fields used in that transaction
i need a list .
thanks&regards
kals.

Hi
you can find all those details in transaction variant,
go with SHD0 ( numerical 0) and then enter your transaction code and enter transaction variant name and then select that
Select the program SAPMV45A and go CHANGE WITH PROCESSING (F6),
there you can find the list of fields and field names.
reward points if usful.
thanks and regards,

What are function modules used in alv,and its explanation

what are function modules used in alv,and its explanation

hi..
The important function modules are
Reuse_alv_fieldcatalog_merge
Reuse_alv_list_display
Reuse_alv_events_get
Reuse_alv_grid_display
Reuse_alv_commentary_write.
REUSE_ALV_FIELDCATALOG_MERGE
 This function module is used to populate a field catalog which is essential to display the data in ALV.
 If the output data is from a single dictionary table and all the columns are selected, then we need not exclusively create the field catalog. Its enough to mention the table name as a parameter (I_structure_name) in the REUSE_ALV_LIST_DISPLAY. But in other cases we need to create it.
Note : Fieldcatalog can be filled manually also by filling up all the required details into the internal table
The important parameters are:
 1. Export:
 a. I_program_name : report id
 b. I_internal_tabname : the internal output table
 c. I_inclname : include or the report name where all
 the dynamic forms are handled.
 2. Changing
 ct_fieldcat : an internal table with the type
 SLIS_T_FIELDCAT_ALV which is declared in the
 type pool SLIS.
REUSE_ALV_LIST_DISPLAY
This is the function module which prints the data.
The important parameters are:
1. Export:
 I_callback_program : report id
 I_bypassing_buffer : X
 I_buffer_active :
 I_callback_pf_status_set : routine where a user can set
 his own pf status or change the
 functionality of the existing pf status.
 I_callback_user_command : routine where the function codes are
 handled.
 I_structure name : name of the dictionary table
 Is_Layout : structure to set the layout of the report
 It_fieldcat : internal table with the list of all fields and their
 attributes which are to be printed (this table
 can be populated automatically by the function
 REUSE_ALV_FIELDCATALOG_MERGE
 It_events : internal table with a list of all possible events
 of ALV and their corresponding form names.
2. Tables:
 a. t_outtab : internal table with the data to be output
REUSE_ALV_EVENTS_GET: 
 Returns table of possible events for a a list type
1. Import:
 Et_Events :
 The event table is returned with all possible CALLBACK events for the specified list type (column NAME). For events to be processed by the Callback, their FORM field must be filled. If the field is initialized, the event is ignored. The entry can be read from the event table, the field FORM filled and the entry modified using constants from the type pool SLIS.
2. Export:
 I_list_type:
 0 = simple list REUSE_ALV_LIST_DISPLAY
 1 = hierarchical-sequential list
 REUSE_ALV_HIERSEQ_LIST_DISPLAY
 2 = simple block list REUSE_ALV_BLOCK_LIST_APPEND
 3 = hierarchical-sequential block list
 REUSE_ALV_BLOCK_LIST_HS_APPEND
REUSE_ALV_GRID_DISPLAY
A new function from 4.6 version, to display the results in grid rather than a
preview.
Parameters : same as reuse_alv_list_display
REUSE_ALV_COMMENTARY_WRITE
This is used in the Top-of-page event to print the headings and other
comments for the list.
It_list_commentary : Internal table with the headings of the type
 slis_t_listheader.
 This internal table has three fields:
 Typ : H - header, S - selection, A - action
 Key : only when typ is S.
 Info : the text to be printed
plz reward pts if helpful.

vijay.

How to find out what are the interfaces used for Job and Job Codes

HI All,
I just wanted to know how do we find out what are the interfaces used for Job and Job codes .
Thanks In Advance
Sunny

Hi,
Here is an idea for your request.
Basically you can create a simple query on multiprovider 0TCT_MC01.
Filter: you can use a variable for restriction of time ( calday, or calmonth) since you should be interested for a time period.
Choose following characters into your objects:
InfoProvider ( 0TCTIFPROV ) - you can create a variable for choosing infoprovider before query runs.
*Tp.[Type of BI Application Object] 0TCTBISOTYP = filter this with 'QUERY' or whatever your need is.
*BI Application Object 0TCTBISBOBJ, ( this will give you the name of the queries)
In key figures choose, Count for BI Appl. (0TCTWTCOUNT).
(number for query run)
Create a condition , for top 20.
Hope this helps.

Benje001,
Right-click on the CWAI control on your form. Choose Properties. The first tab is the Channels tab. After you choose your device from the drop down box on the right, you can type in the Channels box which channel you want to use.
If you want to see a CWAI control that is already configured, all of the shipping examples will have this already done.
Also, if you have questions about any item on the CWAI (or any other NI ActiveX control) you can click the ? icon in the right corner of the properties page and then click on the item in the dialog that you need help with. This "What's this" help will describe that particular control on the dialog.
Hope that helps!

Hi all,
can you please tell me what are the usual date field validations in selection Screen
Thanks and regards ,
Madhavi pilla

Once you declare it as TYPE SY-DATUM, usually that is enough. Sometimes we will also check that it is not less than '18000101' or greater than '99991231'. Or if you have a specific date range that applies to your program you could check the field contents against that. I hope this helps.
