Invoice script changes

Question

Hi all,
I am changing invoice script. My requirement is to select message depends on payment type.
I did check vbdkr structure, but couldn't find payment method type field ZLSCH.
I have to read this from table T052.
SELECT SINGLE FROM T052  WHERE ZTERM = VBDKR-ZTERM.
How can i use this statement in script?
Thanks

Hi
You cannot use the select statment directly in sapscrpit. You need to do the changes in the driver program .If the driver program is standard program then create a subproutine pool as below.
In the layout set use the code
/: DEFINE &V_TEXT& = ' '
/: perform payment_terms in program z_subroutine
/: using &VBDKR-ZTERM&
/: CHANGING &V_TEXT&
THEN DISPLAYE THE &V_TEXT&
In the subroutine pool wirte the below code.
Form payment_terms using it_input structure itcsy
                                changing it_output structure itcsy.
DATA : ZTERM TYPE ZTERM,
           V_VALUE TYPE          "DEFINE THE LENTH REQUIRED.
READ TABLE IT_INPUT INDEX 1.
ZTERM = IT_INPUT-VALUE.
SELECT SINGLE <FIELDNAME> FROM T052
INTO V_VLAUE.
WHERE ZTERM = VBDKR-ZTERM.
IF SY-SUBRC EQ 0.
READ TABLE IT_OUTPUT INDEX 1.
IT_OUTPUT-VALUE = V_VALUE.
MODIFY IT_OUTPUT.
ENDIF.
endform.
Hope the above pseudo code help you to resolve the issue.
