Conversion Exit to Format the Amount with using the respective currency in ALV created by SALV Model.

Preface

In the last article Conversion Exit to format Amounts in ALV, I have demonstrated on how you can achieve the Amount formatting. That formatting was only for one currency $ dollars. I didn’t consider the Currency along with the Amount. So, I knew one of you might ask how, you can achieve it for multiple currencies. Vijay Dudla asked that question on last article.

How this can be done for different currency, suppose if i have a report with different currency and i want different functionality based on currency, how can you find which currency you are doing the conversion in the routine.

Challenges

Conversion Exit accepts the value and convert it to the desired format. Since we can only pass a single Value to the conversion routine, it posed a first challenge to make the solution work.

There is no easy way to identify the currency only from the Amount. I thought of using the DESCRIBE on amount to find out if I can get the associated currency. I also checked the system fields, I can leverage to get the Currency from.

You might think that – Pass the currency to a memory before ALV is generated, access that in the Conversion routine and use it to formulate. But this doesn’t work as you need the currency from corresponding row.

Workable solution

So here is how I kind of solved this:

• Create a Dummy Conversion routine. Assign it to Currency Column. The dummy conversion routine FM needs to be created in the Same FG where the Amount conversion FM is created. In this Dummy Conversion FM, save the currency value to Global Variable.
• Access this global variable in the Amount Conversion Exit to derive the symbol. Use the Symbol to concatenate and make the output

Sounds great, huh? Not that simple. There are few more things to consider

• The Conversion Routine for Currency needs to be executed before the Amount Conversion routine in order to save currency in the global variable. That means the Currency column needs to be before the Amount currency always.
• To make sure, the currency column stays in front of Amount column, I need to implement the event AFTER_SALV_FUNCTION of SALV model. In the event handler, I added logic to renumber the currency and Amount Column.
• You also can’t make the Currency column as currency column for the amount. Doing this, doesn’t trigger the Amount conversion routine at all.
• For Fullscreen, the function “Hide” doesn’t trigger the After SALV event. Thus it renders the ALV incorrect Currency when you hide the Currency column

Conversion Exit for Currency

I created the ZCURR conversion exit for currency. Here is the dummy Conversion for Currency.

 
FUNCTION CONVERSION_EXIT_ZCURR_OUTPUT.
*"----------------------------------------------------------------------
*"*"Local Interface:
*"  IMPORTING
*"     REFERENCE(INPUT) TYPE  CLIKE

*
  output = input.
*
  v_waers_buffer = input.        " Global variable
*
ENDFUNCTION.
 

Redefined Amount Conversion Exit

After adding this new conversion exit FM, here is the redefined version of CONVERSION_EXIT_ZSIGN_OUTPUT

I have hardcoded the currency and Symbols here for demo. But you can create a custom table to store the currency and symbol as suggested by Mohinder in his comment.

 
FUNCTION conversion_exit_zsign_output.

  DATA: lv_symbol TYPE char1.
 
 
  TRY.
      lv_dmbtr = input.
      WRITE lv_dmbtr TO lv_dmbtr_c NO-SIGN.
      CONDENSE lv_dmbtr_c.
      IF lv_dmbtr LT 0.
        CONCATENATE '(' lv_dmbtr_c ')' INTO lv_dmbtr_c.
      ENDIF.
*      WRITE lv_dmbtr_c TO lv_output RIGHT-JUSTIFIED.
*      lv_output+0(1) = '$'.
*
* This can be saved in Config
      CASE v_waers_buffer.
        WHEN 'EUR'.
          lv_symbol = '€'.
        WHEN 'USD'.
          lv_symbol = '$'.
        WHEN OTHERS.
          lv_symbol = '$'.
      ENDCASE.
      CONCATENATE lv_dmbtr_c lv_symbol INTO lv_output SEPARATED BY `   `.
      output = lv_output.
    CATCH cx_root.
  ENDTRY.
ENDFUNCTION.

Program needs to be adjusted to include the event to reset the Currency and Amount columns. Here is the code lines with Event handler
