Problem with IF statement in SAP Script

[#1]

Hi all,

in my SAP Script form two IF statments are evaluated in different ways. Please see the image below.

Both LV_PSP_LEN and LV_HLTST_LEN are calculated in one ABAP subroutine via PERFORM ... ENDPERFORM call.

Seems like the second comparison uses only the first digit of LV_HLTST_LEN.

I tried this values:

LV_HLTST_LEN = 3 => processor evaluates IF &LV_HLTST_LEN& LE '3' to true

LV_HLTST_LEN = 9 => processor evaluates ELSEIF &LV_HLTST_LEN& LE '9' to true

LV_HLTST_LEN = 16 => processor evaluates IF &LV_HLTST_LEN& LE '3' to true

LV_HLTST_LEN = 44 => processor evaluates ELSEIF &LV_HLTST_LEN& LE '9' to true

Please give me some hints to solve my problem.

Regards,

Hubert

Hi Hubert,

What type of fields are LV_HLTST_LEN and LV_PSP_LEN? If they are numeric fields, maybe you should remove the quotes in the if/elseif conditions:

/: IF &LV_HLTST_LEN& LE 3

H1 ,,&LV_HLTST&

/: ELSEIF &LV_HLTST_LEN& LE 9

H2 ,,&LV_HLTST&

/: ELSEIF &LV_HLTST_LEN& LE 16

H3 ,,&LV_HLTST&

/: ELSE

H4 ,,&LV_HLTST&

/: ENDIF

Kind regards,

Rudy.

Hi Rudy,

I don't know wich type SAPscript uses for variables but I think it should use the same type for LV_HLTST_LEN and LV_PSP_LEN.

The interface of the data-delivery-FORM is given by

FORM get_delnote_print_data TABLES in_tab  STRUCTURE itcsy
                                                         out_tab STRUCTURE itcsy.

where ITCSY-VALUE is of type CHAR(255).

The values for both LV_HLTST_LEN and LV_PSP_LEN is calculated like

READ TABLE out_tab ASSIGNING <ls_out_param> WITH KEY 'LV_HLTST'.
IF sy-subrc EQ 0.

    ...
    lv_size = STRLEN( <ls_out_param>-value ).
    READ TABLE out_tab ASSIGNING <ls_out_param> WITH KEY 'LV_HLTST_LEN'.
    IF sy-subrc EQ 0.
        WRITE lv_size TO <ls_out_param>-value.

        SHIFT <ls_out_param>-value LEFT DELETING LEADING space.

    ENDIF.

ENDIF.

thanks,

Hubert

Hi Hubert,

The STRLEN function usually returns an integer. However, itcsy-value is indeed of type CHAR...

Can you try to remove the single quoites from the IF/ELSEIF conditions and see if it works then?

Kind regards,

Rudy.

Hi Rudy,

checked, but did not work.

BTW:

- assigning interger to char converts the int to char

- same approach with LV_HLTST_LEN and LV_PSP_LEN: LV_PSP_LEN works fine, LV_HLTST_LEN does not.

Regards,

Hubert

Hi Hubert,

You are right about the conversion to char. But I'm not sure if your first IF-statement really does work correct.. In the SAP help on the SAPScript IF-statement, there is a note:

• If a syntax error occurs in the interpretation of this command, then the command is not executed. This may have an unexpected effect on the subsequent text output. For example, if the IF statement is incorrect, then all following ELSEIF and ELSE commands will be ignored, since the opening IF command is ‘missing’. This will cause all the text lines attached to the ELSEIF and ELSE commands to be printed.

According to this note it should print &LV_HLTST& multiple times then. I don't know if this is the case.

Anyway, I checked some standard SAP forms and noticed that they close the IF-statement with a period sign:

Maybe that is you syntax error? Can you try to add period sign at the end of each condition?

Kind regards,

Rudy.

Hi again Rudy,

thanks for your continous support.

I checked the form with [Form] -> [Check] -> [Definition]. Result was both times (with and without period sign at end of IF, ELSEIF and ENDIF statement): "No errors found in form ZMM_ABRUF_LEFER"

According to this, the evaluation of the logical expressions did not change with period signs.

&LV_HLTST& is only printed once, with size of the paragraph selected by log.exp. (H1 in case of LV_HLTST_LEN = 16 )

Best regards,

Hubert
