Table controls and step loops

what are the differances between table controls and step loops?

Hi
It's only graphic diff. managed by diff. ways (of course):
in steploop there isn't a table control so in PBO and PAI it has only the stataments LOOP/ENDLOOP or LOOP AT ITAB/ENDLOOP.
The step loop is way older than table control to display the data of a table.

Please advise: if it's possible to include a table control in step loop

Dear Gurus,
Currently, our user want to output a result list after calling BAPI: BAPI_BILLINGDOC_CREATEMULTIPLE.
Because this BAPI could create multiple invoices, and the result is asked to be displayed in a special format (both header information and item information). I just think if it is possible that make the header(text boxes) and item (table control ) in to a step loop.
Could you please kindly advise?
Thanks & Regards

Dear all,
As I tried, it is not possible to include table control or subscreen area in the step loop.

Adding rows to table control or step loop

Hello friends,
I have creazted a table control as data input to ITAB. The user should be able to add more rows if nesseccary to the table during data input.
How can I write the code to enable the user to do this. I would appresiate code as example.
thanks

Hi,
Create a button for insert in the application toolbar..
When the button is pressed..
CASE SY-UCOMM.
WHEN 'INSERT'.
Add new rows.
tc-lines = tc-lines + 20.
TC will be the table control name..
ENDCASE.

Table control and a selection screen

Hi,
I have a requirement where I am supposed to be designing a screen that has a table control with fields
w/selection column       label 1(non-editable)          i/o field(from)        i/o field(to)
w/selection column       label 2(non-editable)          i/o field(from)        i/o field(to)
On searching the forum threads, I found related threads as to how to implement a selection screen (as the I/O fields are similar to select-options) in module pool programming. But mine requires the use of table control and a kind of selection screen embedded into it. Please guide me through this requirement.

Hi
If you need to implement a table control on selection screen u need to use a tabstrip as graphic element supports the table control.
So
1 - Step: define a tabstrip with 1 tab only:
SELECTION-SCREEN BEGIN OF BLOCK 3.
SELECTION-SCREEN BEGIN OF TABBED BLOCK MAX FOR 22 LINES.
SELECTION-SCREEN TAB (25) TABS1 USER-COMMAND UCOMM1
         DEFAULT SCREEN 100.
SELECTION-SCREEN END OF BLOCK MAX.
SELECTION-SCREEN END OF BLOCK 3.
2 - Step design the subscreen (in my sample the dynrpo 100) and insert the table control there:
PROCESS BEFORE OUTPUT.
MODULE INIT_CTRL.
LOOP WITH CONTROL T_CTRL.
    MODULE DISPLAY_DATA.
ENDLOOP.
PROCESS AFTER INPUT.
LOOP WITH CONTROL T_CTRL.
      MODULE UPDATE_DATA.
ENDLOOP.
In the module DISPLAY_DATA and UPDATE_DATA u need to implement the code to transfer the data from internal table to table control and from table control to internal table, in order to display and update the data.

How to insert row in table control and save the data in tables

Hi,
I have one table control i am displaying data into table control ,
my problem is : i want to display data into read mode in table control.
but when i click on insert button on the same screen i want one blank line should inserted into table control , then i want to insert some data into table control on that row , when i click the save button . the new data inserted into the table control is insert that data into ztable ,
please give me solution
main problen is how can know inserted line in table control and pass that data into ztable.

Hi,
Follow the below logic,
PROCESS BEFORE OUTPUT.

       WITH CONTROL CTRL_LP_D516
       CURSOR CTRL_LP_D516-CURRENT_LINE.
The following module moves data to control
    MODULE MOVE_TO_CONTROL.--> Move data from ITAB to table control
ENDLOOP.
PROCESS AFTER INPUT.
LOOP AT GT_CTRL_LP_D516.
ENDLOOP.
MODULE EXIT AT EXIT-COMMAND.

How to use Fuzzy Logic Controller for transfer function in labview control and simulation loop?

I am facing problem with fuzzy PD logic controller for transfer function in control and simulation loop.
Plz Help me in this regard...................
i have attache snapshot of my program

fuzzy in simulation loop.JPG ‏52 KB

Hi Sankhadip,
Sorry for the late response. I was looking at your code and
I noticed that the graph scale does not start from zero. That might be the
reason why you don't see the transient in the simulation. To change the scales
simply double click on the lower limit and set it to zero. If this is not the
expected results, can you please post the expected results, so we can see what are the
differences between the results . Also, you might be using different
solvers, and that gives different results as well.
Thanks and have a great day.

Printing a Table Control AND ALV grid from same report

Hello,
I am trying to figure out how to print the output of my report, which consist of a table control and a OO-driven ALV grid under it. i tried several possibilities but I only get the ALV in my spool....?
Answers will be rewarded !

Keep a break point in that method. Press print in the ALV, check it stops in the break point. If yes then you can use write statement, the values what ever u r writing it come in the print-out. If the control doesn't stop in the break point then there is some problem in the method declartion.
Check my code - I written every thing in the global declaration.

Synchronize Control and Simulation loops

When simulating control systems with LV Control and Simulation loops, I often have multiple loops running at different rates. For example, I have a PWM loop running at 20 kHz, a data acquisition loop running at 100 kHz, and a control loop running at 10 kHz. How can I synchronize all of these loops so that they stay on the same time base? Obviously the master time base will need to be at least as fast as the fastest simulation loop.
I've tried synchronizing all loops to the 1 kHz clock (I'm running on Windows), but each loop runs one period per clock tick (e.g. my 20 kHz loop counts up 50us per clock tick, my 100 kHz loop counts up 10us per clock tick, etc). I need all of the loops to be synchronized to one master time base so the simulation time is identical in each loop, but each loop will be executed at a different rate.
Any thoughts?
Solved!
Go to Solution.

Hello,
A quick suggestion - why can't you run all three systems in a single simulation loop, but have different sample rates for the blocks for each system ?
Is your system entirely digital, or a mixture of continuous and digital - it may simplify things if you can convert everything to discrete time.
Hope this helps,

Resetting Integrator in Control and Simulation Loop

Hello,
I am trying to run a real-time simulation in Labview 14. I have prepared front panel controls and data flow such that I can reset the simulation to some preset initialization values upon clicking a button. However, I am not able to figure out how to reset the integrator in the control and simulation loop. Even after reinitialization of all the values, the integrators will overwrite the initialization values with whatever they were holding. Please help me find a way out.
Thanks

Please share what code you have so that we can see what you've tried and understand exactly what you're trying to do.

Reading the data from table control and write log.

Hi all,
   In va01 trasaction i have table control 'All item'.
   I want to write value of some columns,( Article no, Order, plant ) so on into ecatt Log file after saving the trasction, for all rows which is having article no.
   Is there any possibility in eCATT with going to GETGUI function which is static to spacefic field.
Regards,
Sree

Hi Sreedhar,
There are two types of variable values you find in transactions, one system generated(generally the unique values) and then the static field values..
When you want to go for the static field values you can use GETGUI. You can use the same GETGUI n number of times according to the situation(like in loops etc) and for the system generated messages we can handle them from the message blocks.
MESSAGE.
ENDMESSAGE.
In the message block make a rule for the message that you are expecting like
'E' MSGNR(the message number) and give a variable in the fields MSGV1/MSGV2 where ever you are getting the unique generated value(according to the log) and you can use that variable for LOG purpose..
Confirm me whether you were looking for this or something else.
Best regards,
Harsha

Hi all.
Basically this is what i have done..... I have created a table control in module pool program. I declared an Internal table and also have populated it from a database table. I have also used insert statement to insert an blank record in the table control view and delete statements to delete any record, also in the table control view... .
But I am not able to update any new record into an Internal table or the original table ..

If u have a screen exit..then u will have a option to create a sub screen..in that sub screen u activate the pai and pbo events..it will show u where to write the code..
