When you prepare HTML-data for ‘SO_NEW_DOCUMENT_ATT_SEND_API1’ function module it could be convenient to make a new internal table line for each tag (or several tags). Like this:



But, this approach has certain drawback. In fact, the greater part of each table line would remain unoccupied. Accordingly, the internal table with HTML code would have been looking like this:



But, the line of HTML table has type ‘SOLISTI1’ (CHAR255), consequently, a very large amount of memory remains useless.

When program started, generated inner table has become inadmissibly spacious.

So, as there is a limitation that e-mail can’t be heavier than 20 megabytes, it is often impossible to send large e-mails via ‘SO_NEW_DOCUMENT_ATT_SEND_API1’ FM.

To avoid this, it would be expedient to use following function module to optimize inner table with HTML code:
FUNCTION z_html_optimize.
*"----------------------------------------------------------------------
*"*"Локальный интерфейс:
*" IMPORTING
*" REFERENCE(WHOLE_WORDS) TYPE FLAG DEFAULT ' '
*" REFERENCE(LINE_LEN) TYPE INT4 DEFAULT 255
*" CHANGING
*" REFERENCE(CT_TAB) TYPE RSPC_T_TEXT
*"----------------------------------------------------------------------

TYPE-POOLS abap.

DATA:
l_in_len TYPE i,
l_free_len TYPE i,
l_diff TYPE i,
ls_out TYPE solisti1,
lt_out TYPE rspc_t_text.

FIELD-SYMBOLS:
<s_in> LIKE LINE OF ct_tab.

LOOP AT ct_tab ASSIGNING <s_in>.

l_in_len = STRLEN( <s_in>-line ).
l_free_len = line_len - STRLEN( ls_out-line ).

IF l_in_len <= l_free_len.
CONCATENATE ls_out-line <s_in>-line INTO ls_out-line.
CONDENSE ls_out-line.
ELSE.
IF whole_words = abap_true.
IF l_free_len >= l_in_len.
CONCATENATE ls_out-line <s_in>-line INTO ls_out-line.
CONDENSE ls_out-line.
APPEND ls_out TO lt_out.
CLEAR ls_out.
ELSE.
APPEND ls_out TO lt_out.
CLEAR ls_out.
CONCATENATE ls_out-line <s_in>-line INTO ls_out-line.
CONDENSE ls_out-line.
ENDIF.
ELSE.
IF l_free_len > 0.
CONCATENATE ls_out-line <s_in>-line(l_free_len) INTO ls_out-line.
CONDENSE ls_out-line.
ENDIF.

APPEND ls_out TO lt_out.

CLEAR ls_out.

IF l_free_len < 0.
l_free_len = 0.
ENDIF.

l_diff = l_in_len - l_free_len.

IF l_diff > 0.
CONCATENATE ls_out-line <s_in>-line+l_free_len(l_diff) INTO ls_out-line.
CONDENSE ls_out-line.
ENDIF.

ENDIF.
ENDIF.

AT LAST.
IF l_in_len <= l_free_len.
APPEND ls_out TO lt_out.
ELSE.
IF whole_words = abap_true.
APPEND ls_out TO lt_out.
ELSE.
IF l_diff > 0.
APPEND ls_out TO lt_out.
ENDIF.
ENDIF.
ENDIF.
ENDAT.
ENDLOOP.

ct_tab[] = lt_out[].

ENDFUNCTION.

If you use it like this:



The inner table would have no useless space:



And it would have allowable weight, so FM ‘SO_NEW_DOCUMENT_ATT_SEND_API1’ would easily send derivable e-mail.
