Dynamically Build Tables
I've looked through the forums and found a lot of previous posts regarding dynamic spreadsheets, but I don't think any of them worked quite like this (although I could be wrong).
I have a master table that lists a bunch of items and each item has several columns with information describing that item. For example: Row 1-Ball, Small, Blue, Smooth. Row 2-Cube, Medium, Red, Textured. And so on... This table is not complete and as time goes on I'll have more items to add to it.
Now here's the tricky part: I have other tables that I would like to have their contents build as I add items to the master table. So, when I add Row 3 for a Cylinder the other tables will automatically add the new item to themselves, perform the functions I have laid out, and sort accordingly.
Thank you for your help with this.

Perhaps I'm not properly understanding the solution, but I think mine differs from these examples. Both of these examples are looking for subsets of items from their master tables (only plants with these characteristics or only students from this group). I am looking to have additional tables that still list every single item (ball, cylinder, square), but not all of the fields.
At its most basic, using labels in the header cells of Table 1 for:
"Item" (Column B), "Size" (C), "Colour" (D), "Surface" (E),
the formulas for Table 2, showing only:
"Item" in column B and "Colour) in column C
B: =Table 1::B
C: =Table 1::D
In this form, Table 2 will shot the item name and colour in rows where such information has been entered in Table 1 and zeroes in rows where the data has not yet been entered.
This variation will suppress the zeroes, leaving blank cells in rows where there's no data in Table 1.
B: =IF(LEN(Table 1::B)>0,Table 1::B,"")
Items on Table 2 will be listed in the same order as on Table 1.

Creation of dynamic interal table and fieldcatalog for monat field
Dear Experts,
I am finding the average days of payments giving to our vendors. for this i am passing company code, fiscal year , period and vendor in selection screen.
Based on the period(monat) i need to display the average days and finally i need to display total of the average days. suppose in selection screen if user enters 3 period then the output is like this.
OutPut:
column1 column2 column3 column4 Column5 column6
Vendor No Vendor Name Avg days of paymentsPeriod 1 Avg days of paymentsperiod 2 Avg days of paymentsperiod total Averge days
please advice me to get this output. thanks in advance.Hi,
1.build your fieldcatalog by yourself.
e.g. 4 columns , you will append 4 records in fieldcatalog internal table.
2.use this fieldcatalog internal table to create dynamic internal table by method: cl_alv_table_create=>create_dynamic_table.
3.edit content of dynamic internal table.
4.use alv to display it.
That's all. -
Dynamic internal table column issue
Hi
i have ALV report with dynamic internal table.after i build the internal table and fieldcatalog i have problem i.e. when grid is displayed then one of the column value is coming in the next column.i populated col_pos in field catalog also and in the debug mode data is populated correctly for respective columns in fieldcatalog and dynamic internal table. But when it is displayed i have this problem.
any inputs on this?Hi Moorthy,

Passing Dynamic Internal Tables to Memory
I have a bit of a conundrum right now that I can't seem to correct. I am working on adding an ALV report to an existing report program. I was able to write a simple helper program that builds a custom object that I defined that translates my raw data into two seperate dynamic tables, and then builds an ALV grid and outputs it. The reason I wrote this in a simple helper program was so that I could use SUBMIT ... EXPORTING LIST TO MEMORY from my primary report program and capture the input so I can later write it out under our company's standard ABAP list format as if I were using WRITE statements.
The output of the report itself is working beautifully. We have included functionality to automatically take the output, produce an HTML file from it, and then FTP it directly to a webserver so our clients can get easy access to it. What I want to be able to do though is give the clients two tab-delimited files that contain the raw data that was used to build the report. We have an interface in place to do that, but I somehow need to be able to pass these two dynamic internal tables which I have field-symbols to reference back to my calling program.
Here is what I am trying to do:
CALL METHOD OBJ_ALV_MR_EST_REASONS->PRODUCE_ESTIMATION_REPORT
IMPORTING
RPT_DATA_BY_REASON = ref_it_estreason
RPT_DATA_BY_DISTRICT = ref_it_district.
* Assign the field symbols
ASSIGN ref_it_estreason->* TO <it_estreason>.
ASSIGN ref_it_district->* TO <it_district>.
* Export the two internal tables to memory so they can be
* retrieved by the calling program
EXPORT reason = <it_estreason>[]
district = <it_district>[]
TO MEMORY ID 'ZCR_ESTIMATION_REASON_RPT'.
As you can see, my method returns two references to dynamic internal tables. I have used the memory debugger to see that these tables are being correctly written to the ABAP memory.
However, back in my parent program when I try to do the following,
CREATE DATA ref_it_estreason TYPE REF TO DATA.
CREATE DATA ref_it_district TYPE REF TO DATA.
ASSIGN ref_it_estreason->* TO <it_estreason>.
ASSIGN ref_it_district->* TO <it_district>.
IMPORT reason = <it_estreason>
district = <it_district>
FROM MEMORY ID 'ZCR_ESTIMATION_REASON_RPT'.
I get the REFS_NOT_SUPPORTED_YET exception which says that "For the statement Export/Import ..." object references, interface references, and data references are currently not supported".
I have tried multiple other ways of defining my field-symbols or my reference pointers but they all result in exceptions of some sort. Is there any way for me to get this data passed back? It seems like there must be a way to get the data from memory since I know it's being correctly stored there.
Thanks in advance.Shortly after posting this, I had an idea which I was able to implement to actually get this to work.
I decided that I would simply pass the FIELDCAT tables for each of my dynamic tables into the same memory ID as the tables themselves.
EXPORT reason_fcat = it_estreason_fcat
district_fcat = it_district_fcat
reason = <it_estreason>[]
district = <it_district>[]
TO MEMORY ID 'ZCR_ESTIMATION_REASON_RPT'.
Then, back in my calling program I execute the following code. This retrieves the FIELDCAT tables, builds two empty dynamic table type reference variables and then lets me create field-symbols to reference those components.
* Retrieve the fieldcat internal tables first
IMPORT reason_fcat = it_estreason_fcat
district_fcat = it_district_fcat
FROM MEMORY ID 'ZCR_ESTIMATION_REASON_RPT'.
* Generate an internal table type assigned to each
* reference variable based on the fieldcat listings we
* retrieve
CALL METHOD cl_alv_table_create=>create_dynamic_table
EXPORTING
it_fieldcatalog = it_estreason_fcat
IMPORTING
ep_table = ref_it_estreason.
CALL METHOD cl_alv_table_create=>create_dynamic_table
EXPORTING
it_fieldcatalog = it_district_fcat
IMPORTING
ep_table = ref_it_district.
* Assign the field symbols
ASSIGN ref_it_estreason->* TO <it_estreason>.
ASSIGN ref_it_district->* TO <it_district>.
CREATE DATA ref_wa_estreason LIKE LINE OF <it_estreason>.
CREATE DATA ref_wa_district LIKE LINE OF <it_district>.
ASSIGN ref_wa_estreason->* TO <wa_estreason>.
ASSIGN ref_wa_district->* TO <wa_district>.
* Finally, we can retrieve the data from memory and assign
* to the internal tables referenced by our field-symbols
IMPORT reason = <it_estreason>[]
district = <it_district>[]
FROM MEMORY ID 'ZCR_ESTIMATION_REASON_RPT'.
This worked beautifully and saved me from having to do a major redesign. I don't know how helpful it would be for ABAP Objects to be passed to memory (I believe some type of serialization would need to be in order there), but for dynamically typed internal tables it worked like a dream with little overhead. -

Populating dynamic internal table with data
Hi,
I have an internal table with the data like the below
profit lineId amount
center
s21 70 1000
s21 80 1200
s22 70 800
In the above internal table the number of distinct lineIDs will be vary based on selection-screen creiteria.
So for this I build a fieldcatalog and dynamic internal table like the following
The data available in the above internal table should be placed into the dynamic internal table like the following.
profit
center LineID70 LineID80 .....etc
S21 1000 1200
S22 800
Can any one suggest how to proceed?
Thanks in advance

Before building the display table . you can add the field in the feild catalog right . This display table gets generated from the field catalog right
1 Create a global structute say ZEXTEND_FIELDCAT
2 Have fields like STYLE type lvc_t_styl
COLOR type LVC_T_SCOL.
3 Now you have to extend ur fieldcatalog
l_fieldcat-fieldname = COLOR'.
l_fieldcat-ref_field = 'COLOR'.
l_fieldcat-ref_table = 'ZEXTEND_FIELDCAT'.
APPEND l_fieldcat TO lt_field_catalog.
CLEAR l_fieldcat. -
Dynamically build parameter list
I'm after an easy way to dynamically build a list of ALL the defined parameters within the additional PL/SQL code section on a portal report. I then want to use p_arg_names / p_arg_values to retrieve and store the passed values in a table.
To clarify, the report may have 10 parameters of which say only 5 are passed on a particular run. I need to then populate 10 columns which includes nulls for the parameters not passed. This way parameter values will always be written to the same column.
I aiming to use this as generic code to apply to several other reports which will write to the same table.
RonIn case anyone else needs this I'll post the solution myself.
1. p_arg_names and p_arg_values (shows only the populated parameters / values)
2. l_arg_names and l_arg_values (shows all the parameters / values)
So in my case I needed to reference l_arg_names and l_arg_values. -
Setting a Filter on a dynamically created Table
Hi All,
I am currently working on a Database to automatize some process. Quick explanation:
The User can import a CSV (Text) File via a DialogBox, which gets imported into a Table. After this, the content has to be filtered, setting conditions on 4 different rows. The new Table gets exported into a new CSV (It has to be CSV, since it later gets imported
into SAP)
I am having some trouble with filters though:
How can I set a Filter on a dynamically created Table (using VBA)?
Best case would be to save the filter into my Import spec, but Access doesn't seem to have this option (?)
Can somebody help?
Thanks in advance
Regards
AlexThanks for the fast reply! Sorry, I am not really proficient at Access. How do I do a query on a dynamically created Table? Do I have to save the Table into a Variable. Or what's the way to import it?
Hi Alex,
I never use the Import functionality, nor DoCmd.TransferText.
To import data from a csv-file I made my own Import functionality. In fact it is just reading an external file, line by line, and each line field by field using the field separator. In my opinion that is far more versatile than the standard functionality.
But you can use the standard functionality of Access to import a csv-file into a table.
Having the data in a table, you can generate the appropriate query for the output in a VBA procedure:
sql_string = "SELECT Field1, Field2, ... FROM MyTable WHERE Field1 = ... AND Field2 = ... ORDER BY Field3"
and make a recordset of it:
Set cur_set = CurrentDb(sql_string)
The output csv-file is then filled by opening a file for Write, loop through all the records, concatenate for each record all the wanted fields using the field separator, and write the result line to the csv-file.
Most important is to understand this process. After that it should be possible to build it. And if you have further questions, just ask.

Create object/structure like dynamic internal table
Hi,
We have created dynamic internal table with some fields.
for the above how to create structure or internal table like dynamic internal table structure .
Scenario: internal table itab1 ( with header line) have 5 fields.
Based on some of the conditions in layout of the report.
we have to create dynamic internal table.
field-symbols: <FS> type standard table.
we are able to create dynamic internal table with 3 fields
with assignment <fs> = itab1[]
the columns are not appearing but data appearing in next column.
how to solve this one
Thanks

Reference comp in dynamic internal table using CL_ALV_TABLE_CREATE
Hi,
I am using CL_ALV_TABLE_CREATE to create a dynamic internal table. Everything works fine, but there is one problem with it. How can i create a component in the internal table that is actually a REF TO a certain data type. i.e. later i would like to store a reference to some dataobj in this component of the internal table.
I cannot use cl_abap_*descr classes to create internal table because of some other reasons, otherwise it would have been easy to do it.
Any kind of help would be highly appreciated.
Thanks and best regards,
