ABAP String templates Examples

Posted by -

 After talking about string templates in the last post String processing using string templates, I was tempted to provide more examples of just how powerful and simple to use string templates can be. so without much writing, here we go.

Adding Whitespaces and Comments:

report syst-repid.
DATA:
lv_String TYPE string.
START-OF-SELECTION.
lv_String = |line 1;\n| & " the 1st line
* This is a comment ,, the string template still continues
| line{ 1 + 1 }| &
* The previous line still continues.
| (still line { 1 + 1 });\n| &
| line { 1 + 2 };|.
cl_demo_text=>show_string( lv_String ).

Control and escape Characters: 

report syst-repid.
DATA:
lv_String TYPE string.
DATA:
i1 TYPE i.
START-OF-SELECTION.
lv_String = |Printing Linebreak:\n.Printing Tab: \t. Printing Reserved Characters: \\, \{, \}.|.
cl_demo_text=>show_string( lv_String ).

Format Options: 

    Width, Alignment, Padding, Zero, Case

report syst-repid.
DATA:
lv_String TYPE cl_demo_text=>t_line.
DATA:
lv_int TYPE i,
lv_float TYPE f,
lv_txt TYPE string.
DATA:
lo_txt TYPE REF TO cl_demo_text.
START-OF-SELECTION.
lo_txt = cl_demo_text=>get_handle( ).
lv_String = |[{ 12 WIDTH = 5 ALIGN = LEFT }]| &
|[{ 12 WIDTH = 5 ALIGN = CENTER }]| &
|[{ 12 WIDTH = 5 ALIGN = (cl_abap_format=>a_RIGHT) }]| &
|[{ lv_int WIDTH = 5 ZERO = NO }]| &
|[{ lv_int WIDTH = 5 ZERO = YES }]|.
lo_txt->add_line( lv_String ).
lv_String = |[{ 12 WIDTH = 5 ALIGN = LEFT PAD = '.' }]| &
|[{ 12 WIDTH = 5 ALIGN = CENTER PAD = '.' }]| &
|[{ 12 WIDTH = 5 ALIGN = RIGHT PAD = '_' }]| &
|[{ lv_float WIDTH = 5 PAD = '_' ZERO = NO }]| &
|[{ lv_float WIDTH = 5 PAD = '_' ZERO = YES }]|.
lo_txt->add_line( lv_String ).
lv_txt = |I am YELLING.|.
lv_String = |[ { lv_txt } ] [{ lv_txt CASE = LOWER }]|.
lo_txt->add_line( lv_String ).

    Sign, Decimals, Exponent, Currency, Number, Style:

report syst-repid.
DATA:

lv_txt TYPE string.
DATA:
lo_txt TYPE REF TO cl_demo_text.
START-OF-SELECTION.
lv_float = '0.75'.
lv_int = 55.
lo_txt = cl_demo_text=>get_handle( ).
lv_String = |Left: [{ lv_float SIGN = LEFT }] [{ lv_float SIGN = LEFTPLUS }] [{ lv_float SIGN = LEFTSPACE }]| &
|Right: [{ lv_int SIGN = RIGHT }] [{ lv_int SIGN = RIGHTPLUS }] [{ lv_int SIGN = RIGHTSPACE }]|.
lo_txt->add_line( lv_String ).
lv_String = |DECIMALS:[{ lv_int DECIMALS = 1 }] [{ lv_float DECIMALS = 1 EXPONENT = -3 }]|.
lo_txt->add_line( lv_String ).
"Currency
lv_String = |CURRENCY:[{ lv_int CURRENCY = 'EUR' }][{ lv_float CURRENCY = 'USD' }]|.
lo_txt->add_line( lv_String ).
"Decimal separators
lv_int = 123456789. lv_float = '1234.0625'.

| [{ lv_float NUMBER = RAW }] [{ lv_float NUMBER = (cl_abap_format=>n_USER) }]|.

"style (as in WRITE)
lv_float = '-2.345'.
lv_String = |STYLE:[{ lv_float STYLE = SIMPLE }] [{ lv_float STYLE = SCIENTIFIC }]| &
| [{ lv_float STYLE = SIGN_AS_POSTFIX }]|.

ABAP convert internal table to excel (.xlsx) format and Send email or download

Posted by -
Reporting is incomplete without file interfacing. Sometimes the requirement is to send a file via email or download it to a PC. but what to do when the user requests the file in XLSX format? In today's post, I am sharing how to convert an internal table to .xlsx format and then send it to a PC or email. One of the quickest ways I found it been done is using SALV classes. Below is the Code snippet Now once you have the xstring with you, simply pass it to relevant libraries to handle the output. Downloading to PC: Sending via Email It's that simple. Hope you like the post and use it in your day to day work.

ABAP read excel(.XLSX) file to internal table in ABAP using CL_FDT_XL_SPREADSHEET

Posted by -
You are given a requirement to upload data to a custom DB table where the user provides you with the file path of the excel on his PC and the report loads the data from it to the Custom table. For experienced Abapers, the requirement is quite straightforward, except that the user wants to upload an XLSX file. There are not many options to read data from XLSX/XLS file. The TEXT_CONVERT_XLS_TO_SAP  function module is one of them but is a performance killer and uses OLE. In this post, I wanted to showcase How we can read data from the XLSX files using CL_FDT_SPOREADSHEET class. Let's start with uploading the file. Now that we have the file in xstring table, let's pass it to CL_FDT_XL_SPREADSHEET to get its object reference. From the object reference, we can retrieve each worksheet data. The data is returned in the form of an anonymous data object which can be dereferenced into a field symbol and passed to the target internal table. Below is the co...

Use CL_BCS library to send email with ABAP

Posted by -
Many a time you need a report for which the output needs to be an email. SO_NEW_DOCUMENT_SEND_API1 is heavily used to achieve the task but let's explore another way of achieving the same using CL_BCS. This post talks about how to use the CL_BCS library provided by SAP to easily send emails. CL_BCS Library The class serves as the interface from BCS to the applications. The methods of the class cater for the send functions. Using CL_BCS, You can: – Attach files to email – Build the HTML/raw of the body. – Set email’s Senders & Receiver – Send an email, etc. Let's see the steps one by one: Initiating CL_BCS: The first thing you need is to initiate a persistent send request. Creating BCS Document: Create the BCS document object which will be sent with the CL_BCS interface to BCS. In this case the Email. SET_DOCUMENT Once we have the document, It needs to be set to the send request. SET_SENDER Assign the sender to the send request. ADD_RECIPIENT Pass ...
