ESB problem when use merge function in master/detail relationship

I have some problem with the merge function in database adapter.
details:
I have 2 tables in master/detail relationship, both have GUID column as a primary key (GUID generated by ESB).
'car_group' table
pk : guid
unique : group_no, datadate, datatime
===============================
guid, group_no, datadate, datatime, group_detail
===============================
1, 1, 01/01/2008, 09:00, groupdetail01
2, 1, 01/01/2008, 10:00, groupdetail02
'car_group_detail' table
pk : guid
fk : car_group_guid link to car_group.guid
==================
guid, car_group_guid, detail
==================
1, 1, detail01
2, 1, detail02
3, 2, detail03
4, 2, detail04
I used a file adapter as a input, here is an example text file
M, 1, 01/01/2008, 09:00, groupdetail01
D, detail01
D, detail02
M, 1, 01/01/2008, 10:00, groupdetail02
D, detail03
D, detail04
Because I used merge function so I need to specify the columns that will be a condition for the insert/update,
but I have generate GUID as a primary key in the tables, I can't used it, so in toplink I map my unique key as a primary key.
The insert operation work fine but when update is required (for example, try to change 'group_detail' column of the master table in text file),
an SQLException thrown, the log file shown the adapter try to update the GUID column of master table but the constraint not allowed.
And yes, cause of GUID generate everytime so ESB try to update this column also, but I don't want to do like that, I need something
like when update operation required, just ignored the GUID column.
I try to mark read-only to the GUID column in Toplink mapping file but still have the same problem, it still generate UPDATE statement
with the GUID column, and also I try to let the database trigger to generate GUID instead of ESB function, but it not works in master/detail
relationship (I think the Toplink manage the relationship, is it right ?)
Please advise, thanks for advance.

somebody please help, thanks !!!

Field catalog issue using REUSE_ALV_FIELDCATALOG_MERGE

Hello experts,
I am using FM REUSE_ALV_FIELDCATALOG_MERGE and the field catalog is created fron the program.
The field catalog finds the date field from the program but my internal table has been changed to make the date output YYYY/MM/DD.
When I input the internal table in FM REUSE_ALV_GRID_DISPLAY the output displays the date as DD/MM/YYYY which is not what I want.
How can I get FM REAUSE_ALV_GRID_DISPLAY to output the date in the format YYYY/MM/DD which is in my input table.
I have spent a lot of time researching SDN on this but cannot find a similar solution however I did find some examples of changing the field catalogue. Can anybody suggest this is the way to go and if I would use the edit mask field in the field catalog or is there a better way.
Thanks for any suggestions

I think you can use a field exit for this.
This means creating a field element and a domain in the data dictionary, the domain will need to have a conversion exit set by putting an entry in the 'Convers. Routine' field, eg MYDAT.
You will need to create two function mdules as below:
eg, CONVERSION_EXIT_MYDAT_OUTPUT
and CONVERSION_EXIT_MYDAT_INPUT
Your internal table will now need to refer to the data element you have created instead of the one you are currently using. ALV should automatically pick up the conversion exits and show the ouitput as you desire.
FUNCTION CONVERSION_EXIT_MYDAT_OUTPUT.
""Local Interface:
*" IMPORTING
*"     REFERENCE(INPUT) TYPE DATS
*" EXPORTING
*"     REFERENCE(OUTPUT)
concatenate input(4) '/' input4(2) '/' input6
into output.
ENDFUNCTION.
FUNCTION CONVERSION_EXIT_MYDAT_INPUT.
""Local Interface:
*" IMPORTING
*"     REFERENCE(INPUT)
*" EXPORTING
*"     REFERENCE(OUTPUT) TYPE DATS
data l_string type string.
l_string = input.
replace all occurrences of '/' in l_string with ' '.
output = l_string.
ENDFUNCTION.

in that function module what i want to give the Exporting Object 'HOGO'. where i want to define the number range. what is meant by 'HOGO'.
If any one faced the same problem plz help me.
Thanks and regards,

Field catalog issue

Hi ppl
       I am building a field catalog for standard table 'API_VALI' , why am I not getting field catalog in xfield?

As ABAP_TECHINCAL has written, for standard tables you don't have to send the parameter i_internal_tabname . Instead you have to send the table name in the parameter i_structure_name.

Doubt in using field catalog merge function

hi all,
    When I am using the function maodule reuse_alv_fieldcatalog_merge for building the field catalog in alv list,it was giving abend message as
'Field catalog is empty'.
     what might be the reason for such message?can some one help me out with the solution to get rid of that.
    I cant populate the catalog manually because I need to display nearly 40 fields in the output.
         Thanks in advance.

hI
Supports the creation of the field catalog for the ALV function modules
based either on a structure or table defined in the ABAP Data
Dictionary, or a program-internal table.
The program-internal table must either be in a TOP Include or its
Include must be specified explicitly in the interface.
The variant based on a program-internal table should only be used for
rapid prototyping since the following restrictions apply:
o Performance is affected since the code of the table definition must
always be read and interpreted at runtime.
o Dictionary references are only considered if the keywords LIKE or
INCLUDE STRUCTURE (not TYPE) are used.
If the field catalog contains more than 90 fields, the first 90 fields
are output in the list by default whereas the remaining fields are only
available in the field selection.
If the field catalog is passed with values, they are merged with the
'automatically' found information.
Below is an example ABAP program which will populate a simple internal table(it_ekpo) with data and
display it using the basic ALV grid functionality(including column total). The example details the main
sections of coding required to implement the ALV grid functionality:

Hierarchical alv list field catalog

hi, i am diplaying a hierarchical list through ooalv.
i am using the cl_salv_hierseq_table=>factory method.
CALL METHOD cl_salv_hierseq_table=>factory
EXPORTING
    t_binding_level1_level2 = lt_binding
IMPORTING
    r_hierseq               = gr_table
CHANGING
    t_table_level1          = T_HEADER
    t_table_level2          = T_ITEM.
Could anyone please tell me how do i pass a FIELD CATALOG in the above function.
I checked the parameters of the above function and it has only 4 parameters
as used above.

When you create the ALV using the SALV OM, system creates the Field Catalog and some default setting based on the table columns. So, change any of the column properties, you have to get the Column object and process the column.
Check the program SALV_DEMO_HIERSEQ_COLUMN.

How to use a function module in a subroutine

Hi,
I am working on a report where i have to create list boxes for 5 fields.Instead of using the function module VRM_SET_VALUES for each field can i use subroutine?
If so, can anyone tell me the procedure for that?Its very urgent.
Thanks and Regards,
Hema

Hi,
   I have written the code like this.
FORM VALUE USING V_NAME.
CALL FUNCTION 'VRM_SET_VALUES'
    EXPORTING id     = v_name
              values = v_list.
ENDFORM.
AT SELECTION-SCREEN OUTPUT.
REFRESH V_LIST.
v_name = 'P_COMMER'.
v_value-key = 'C'.
v_value-text = 'Commercial'.
APPEND v_value TO v_list.
v_value-key = 'N'.
v_value-text = 'Non-Commercial'.
APPEND v_value TO v_list.
v_value-key = ' ' .
v_value-text = 'Both'.
APPEND v_value to v_list.
PERFORM VALUE USING V_NAME.
REFRESH V_LIST1.
v_name1 = 'P_DIRECT'.
v_value1-key = 'D'.
v_value1-text = 'Direct'.
APPEND v_value1 to v_list1.
v_value1-key = 'I'.
v_value1-text = 'Indirect'.
APPEND v_value1 to v_list1.
PERFORM VALUE USING V_NAME1.
REFRESH V_LIST2.
v_name2 = 'P_DIR'.
v_value2-key = 'D'.
v_value2-text = 'D'.
APPEND v_value2 TO v_list2.
v_value2-key = 'C'.
v_value2-text = 'C'.
APPEND v_value2 TO v_list2.
v_value2-key = ' ' .
v_value2-text = ' '.
APPEND v_value2 to v_list2.
PERFORM VALUE USING V_NAME2.
REFRESH V_LIST3.
v_name3 = 'P_LOW'.
v_value3-key = 'Y'.
v_value3-text = 'Yes'.
APPEND v_value3 TO v_list3.
v_value3-key = 'N'.
v_value3-text = 'No'.
APPEND v_value3 TO v_list3.
v_value3-key = ' ' .
v_value3-text = ''.
APPEND v_value3 to v_list3.
PERFORM VALUE USING V_NAME3.
REFRESH V_LIST4.
v_name4 = 'P_PARENT'.
v_value4-key = 'P'.
v_value4-text = 'Parent'.
APPEND v_value4 TO v_list4.
v_value4-key = 'C'.
v_value4-text = 'Child'.
APPEND v_value4 TO v_list4.
v_value4-key = ' ' .
v_value4-text = ''.
APPEND v_value4 to v_list4.
PERFORM VALUE USING V_NAME4.
REFRESH V_LIST5.
v_name5 = 'P_PREF'.
v_value5-key = 'P'.
v_value5-text = 'Preferred'.
APPEND v_value5 TO v_list5.
v_value5-key = 'N'.
v_value5-text = 'NotPreferred'.
APPEND v_value5 TO v_list5.
v_value5-key = ' ' .
v_value5-text = ''.
APPEND v_value5 to v_list5.
PERFORM VALUE USING V_NAME5.
Now I am getting the same set of values in all the fields.How can I solve this?
Thanks and Regards,
Hema

Field catalog of internal tables

Is it possible to get the field catalog of an internal table which is received as a parameter (TYPE ANY TABLE) of a function? I would like to pass the field catalog directly to the function

Pls help.

When do we need field catalog merge in ALV

Hi all,
When do we actually need fieldcatalog merge in ALV's
Regards
Saroja.

Hi
When you want the field catalog to be populated directly from the internal table or a structure, you can use this function module. If you are populating the field catalog from an internal table in an include other than your top include, then the include name also has to be passed to the function module.
reward if helpful

OTHERS = 3.
*Pass that field catalog into the fillowing FM
call function 'REUSE_ALV_GRID_DISPLAY'
       exporting
