How to escape ampersand in message text? - abap

I created a message class which contains the following text
No K&C Data available for &1
DATA ls_return TYPE bapiret2.
DATA lv_par1 TYPE sy-msgv1 .
lv_par1 = '123456' .
CALL FUNCTION 'BALW_BAPIRETURN_GET2'
EXPORTING
type = 'I'
cl = 'Z_MY_MESSAGE_CLASS'
number = 021
par1 = lv_par1
IMPORTING
return = ls_return.
WRITE ls_return-message .
The output of the small example programm will be
No K123456C Data available for 123456
but should be
No K&C Data available for 123456
So how do I escape(?) or change the entry of my message class?

You need use it as couple like below:
No K&&C Data available for &1

Assigning Field Symbols to Internal Table

I'm trying upload Excel file to internal table in ABAP. I'm using function GUI_UPLOAD and then SCMS_BINARY_TO_XSTRING. At last I have field sybmbol <gt_data> with data from Excel file.
DATA(lo_data_ref) = lo_excel_ref->if_fdt_doc_spreadsheet~get_itab_from_worksheet(
lv_woksheetname ).
*-- Excel work sheet data in dyanmic internal table
ASSIGN lo_data_ref->* TO <gt_data>.
A [CString]
B [CString]
data1
data11
data2
data22
data3
data33
How I can iterate <gt_data> to internal table? I would try like below, but I received dump.
TYPES: BEGIN OF lty_test,
A TYPE string,
B TYPE string,
END OF lty_test.
DATA: lt_test_table TYPE STANDARD TABLE OF lty_test.
As far as I understood, you want to read excel rows with this code.
LOOP AT <gt_data> ASSIGNING FIELD-SYMBOL(<ls_data>).
ENDLOOP.
I am not sure struct of <ls_data> but I think you can read it with index for get to know main idea.
Could you try it like below?
CHECK <gt_data> IS ASSIGNED.
"It's column count for excel file. It can be found dynamically.
DATA(lv_column_count) = 10.
"Loop for rows.
LOOP AT <gt_data> ASSIGNING FIELD-SYMBOL(<ls_data>).
"Loop for columns
DO lv_column_count.
ASSIGN COMPONENT sy-index OF <ls_dat> TO FIELD-SYMBOL(<lfs_value>).
ENDDO.
ENDLOOP.
So first you need to declare a structure for the internal table and each field in the structure should have type "string".
Types:begin of ty_upload,
Field1 type string,
Field2 type string,
End of ty_upload.
Data:it_upload type standard table of ty_upload.
It_upload[] = <gt_data>
Now internal table it_upload should have the data from the field value
Try this:
file = 'C:\xyz.XLS'.
CALL FUNCTION 'ALSM_EXCEL_TO_INTERNAL_TABLE'
EXPORTING
filename = file
i_begin_col = '1'
i_begin_row = '1'
i_end_col = '5'
i_end_row = '6000'
TABLES
intern = xcel
EXCEPTIONS
inconsistent_parameters = 1
upload_ole = 2
OTHERS = 3.
LOOP AT xcel.
" xcel is an internal table and has field xcel-value
ENDLOOP.

READ TABLE WITH TABLE KEY does not find record

I'm trying to use the class /ui5/cl_json_parser for parsing a JSON string.
The following code snippet reproduces the problem:
REPORT ztest_json_parse.
DATA: input TYPE string,
output TYPE string,
json_parser TYPE REF TO /ui5/cl_json_parser.
input = '{"address":[{"street":"Road","number":"545"},{"street":"Avenue","number":"15"}]}'.
CREATE OBJECT json_parser.
json_parser->parse( input ).
json_parser->print( ).
output = json_parser->value( path = '/address/1/street' ).
WRITE output.
The print method shows the correct parsed JSON string, but the output variable is always empty.
I have traced the code down to the method VALUE of the class /UI5/CL_JSON_PARSER, at line 15, which contains:
read table m_entries into l_entry with table key parent = l_parent name = l_name.
In the debugger, I can see that l_parent = '/address/1' and l_name = 'street', and that the internal table m_entries contains a record with parent = '/address/1' and name = 'street'. Nevertheless the READ statement always returns sy-subrc = 4 and does not find anything.
Can anyone help?
First: Do not use /ui5/cl_json_parser class, it is intended for internal use ONLY and has no reliable documentation
Secondly, here is the sample how you can fetch street value from the first element of your JSON:
DATA(o_json) = cl_abap_codepage=>convert_to( '{"address":[{"street":"Road","number":"545"},{"street":"Avenue","number":"15"}]' ).
DATA(o_reader) = cl_sxml_string_reader=>create( o_json ).
TRY.
DATA(o_node) = o_reader->read_next_node( ).
WHILE o_node IS BOUND.
DATA(op) = CAST if_sxml_open_element( o_node ).
LOOP AT op->get_attributes( ) ASSIGNING FIELD-SYMBOL(<a>).
DATA(attr) = <a>->get_value( ).
ENDLOOP.
IF attr <> 'street'.
o_node = o_reader->read_next_node( ).
ELSE.
DATA(val) = CAST if_sxml_value_node( o_reader->read_next_node( ) ).
WRITE: '/address/1/street =>', val->get_value( ).
EXIT.
ENDIF.
ENDWHILE.
CATCH cx_root INTO DATA(e_txt).
ENDTRY.
As far as I know, there is no class in ABAP that allows fetching single JSON attributes like XPath.
Certainly agree with Suncatcher on avoid UI5 Json parser.
If you dont control/know the structure of the source data, Suncatchers answer is good.
However,
if you know the basic structure of the source JSON and you must, if you plan to access the first address row, fieldname street .
AND you can have the source provided using uppercase variable names then you can use the so called identity transformation.
types: begin of ty_addr,
street type string,
number type string,
end of ty_addr.
types ty_addr_t type STANDARD TABLE OF ty_addr.
DATA: input TYPE string,
ls_addr TYPE ty_addr,
lt_addr type ty_addr_t.
input = '{"ADDRESS":[{"STREET":"Road","NUMBER":"545"},{"STREET":"Avenue","NUMBER":"15"}]}'.
CALL TRANSFORMATION id SOURCE XML input
RESULT address = lt_addr.
read table lt_addr index 1 into ls_addr.
WRITE ls_addr-street.

How to get long texts of FI held documents?

I need to get the particulars/long text of FI held documents. I tried the 'read_text' function module but had no luck since the held document has the temporary document number.
I tried looking for data in STXL and STXH tables, I also tried the function modules in FM group FTXT and STXD but had no luck.
Any other method to achieve that goal?
First of all, you need the temporary document number which can be get either from F-43 itself or from RFDT table.
In field SRTFD you should separate it from username.
Then run READ_TEMP_DOCUMENT FM, after running it you should have your texts in ABAP memory.
To get them use GET_TEXT_MEMORY.
ls_uf05a-tempd = '0012312356'. "doc number
ls_uf05a-unamd = 'JOHNDOE'. "username
CALL FUNCTION 'READ_TEMP_DOCUMENT'

I_UF05A = ls_uf05a

Create dynamic ABAP internal table

On selection screen, the user needs to insert a table name, and I need to get first 3 fields from that table and display them in an ALV for the output. What I understand from reading tutorials is that I need to call method cl_alv_table_create=>create_dynamic_table, but I don't know how to create the fieldcatalog.
DATA: t_newtable TYPE REF TO data,
t_fldcat TYPE lvc_t_fcat,
CALL METHOD cl_alv_table_create=>create_dynamic_table
EXPORTING
it_fieldcatalog = t_fldcat
IMPORTING
ep_table = t_newtable.
I assume that the table name which user enters is a data dictionary table (like SFLIGHT). If yes, then you can generate the field catalog as follows.
data : it_tabdescr type abap_compdescr_tab,
wa_tabdescr type abap_compdescr.
data : ref_table_descr type ref to cl_abap_structdescr.
ref_table_descr ?= cl_abap_typedescr=>describe_by_name( p_table ).
it_tabdescr[] = ref_table_descr->components[].
loop at it_tabdescr into wa_tabdescr.
clear wa_fieldcat.
wa_fieldcat-fieldname = wa_tabdescr-name .
wa_fieldcat-datatype = wa_tabdescr-type_kind.
wa_fieldcat-inttype = wa_tabdescr-type_kind.
wa_fieldcat-intlen = wa_tabdescr-length.
wa_fieldcat-decimals = wa_tabdescr-decimals.
append wa_fieldcat to it_fieldcat.
endloop.
Here, "p_table" is the selection screen parameter containing the table
name.

How to use REUSE_ALV_FIELDCATALOG_MERGE function module?

The REUSE_*ALV* function modules are unsupported. I'd suggest switching to the CL_SALV_* classes. The documentation is better, there are more sample programs (DEMO_SALV_*) and you get support.
You need a dictionary structure if you want to get dictionary-based field descriptions (duh). If you assemble a structure type on the ABAP level using TYPE ... BEGIN OF ... END OF ..., as far as I know, the dictionary types for the individual fields are converted to ABAP types first and only then assembled into a structure type. Anyway, the dictionary reference of the original fields is lost. Instead of defining the structure of the output table in your code, use a dictionary structure.
You have some mistakes you might have not known (SAP is very confusing sometimes
and not transparent with error-messages). I got for you a working example of mine, have a look on it, especially on the comments.
First, data definition:
TYPE-POOLS slis. "import you need for REUSE_ALV_FIELDCATALOG_MERGE
DATA:
lt_fieldcat TYPE slis_t_fieldcat_alv,
BEGIN OF G_IT_MATERIAL occurs 0,
MATNR LIKE MARA-MATNR,
MTART LIKE MARA-MTART,
MAKTX_DE LIKE MAKT-MAKTX,
MAKTX_FR LIKE MAKT-MAKTX,
MAKTX_IT LIKE MAKT-MAKTX,
ERNAM LIKE MARA-ERNAM,
ERSDA LIKE MARA-ERSDA,
LAEDA LIKE MARA-LAEDA,
END OF G_IT_MATERIAL.
It is absolutely necessary that you define your local structure directly with LIKE, otherwise the parser from REUSE_ALV_FIELDCATALOG_MERGE will not find it.
Select your stuff:
SELECT ma~matnr ma~mtart ma~ernam ma~ersda ma~laeda
de~maktx as maktx_de fr~maktx as maktx_fr it~maktx as maktx_it
FROM mara as ma
LEFT JOIN MAKT as de ON de~matnr = ma~matnr AND de~spras = 'DE'
LEFT JOIN MAKT as fr ON fr~matnr = ma~matnr AND fr~spras = 'FR'
LEFT JOIN MAKT as it ON it~matnr = ma~matnr AND it~spras = 'IT'
INTO CORRESPONDING FIELDS OF TABLE g_it_material
WHERE ...
Create a field catalog dynamically:
CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'
EXPORTING
I_PROGRAM_NAME = sy-repid
I_INTERNAL_TABNAME = 'G_IT_MATERIAL'
I_INCLNAME = sy-repid

ENDIF.
Now display the ALV grid:
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
EXPORTING
it_fieldcat = lt_fieldcat "you could also give a structure
"i_structure_name = 'ZMM_SMATERIAL' "here instead of the fieldcat
TABLES
t_outtab = g_it_material
EXCEPTIONS
program_error = 1
OTHERS = 2.
Note that the parser also needs a max linesize of 72 chars.
There are several different text components provided by structure slis_fieldcat_alv that are used as column labels. The chosen text depends on the current column width (which itself usually depends on the length of the data displayed). Make sure that you change them all accordingly!
The usual technique is: By passing the I_STRUCTURE_NAME, you get a field catalog corresponding to this DDIC structure (the changing parameter ct_fieldcat). You then modify this internal table according to your needs and pass that modified table to the REUSE_ALV_GRID_DISPLAY.
In cases where I don't distinguish the different-sized text versions, I use the following macros to set all the text fields to the same value. The macros require a local work area ls_fieldcat (with the linetype of ct_fieldcat) and a local string variablelv_text` in order to work.
define set_field.
* Feld &1 für Anzeigefeld &2 den Wert &3 zuweisen
ls_fieldcat-&1 = &3.
modify ct_fieldcat from ls_fieldcat
transporting &1
where fieldname cp '&2'.
end-of-definition.
define set_text_direct.
lv_text = &2.
set_field seltext_s &1 lv_text.
lv_text = &2.
set_field seltext_m &1 lv_text.
lv_text = &2.
set_field seltext_l &1 lv_text.
end-of-definition.
