Making condition type unmandatory for free item categories

Question

Hi all,
I've created a form routine in RV64ANNN the requirement is when we create or change sales order....we have few item categories were in we need to make a concern condition type unmandtory if items with those item category is created...else if make the condition type mandatory.........example...............this is done for only one pricing procedure......in V/08 tcode and there i've assinged our routine number for that condition type which needs to be changed dynamically.
say we have Sales doc type ZXXX for this sales doc type lets say we have item category ZITE1 and ZITE2.......and lets say the Condition type is ZCOND(whether the condition type is required or not is done by checking in tcode V/08 and this is always checked).now when the user enters creates a item 1 with item category ZITE1 and leaves the amount field blank it will however ask to enter the amount.......now here is the problem............if user creates second line item with item category ZITE2 its againing asking to enter the amount for that condition type.............this is happing even after i've desinged the below code.............
DATA: l_kobli TYPE kobli.
IF komk-kalsm = 'ZINFAM'.
*Sale Doc ZORA
IF komk-auart = 'ZORA'.
IF komp-pstyv = 'ZTAN'.
l_kobli = 'X'.
ELSEIF komp-pstyv = 'ZZNN' OR
komp-pstyv = 'REN'.
l_kobli = ' '.
ENDIF.
*Sale Doc ZORB
ELSEIF komk-auart = 'ZORB'.
IF komp-pstyv = 'TAN'.
l_kobli = 'X'.
ELSEIF komp-pstyv = 'REN' OR
komp-pstyv = 'TANN'.
l_kobli = ' '.
ENDIF.
*Sale Doc ZRE
ELSEIF komk-auart = 'ZRE'.
IF komp-pstyv = 'REN' OR
komp-pstyv = 'RENN'.
l_kobli = ' '.
ENDIF.
*Sales Doc ZCOR
ELSEIF komk-auart = 'ZCOR'.
IF komp-pstyv = 'KRN' OR
komp-pstyv = 'RENN'.
l_kobli = ' '.
ENDIF.
*Sales Doc ZCI
ELSEIF komk-auart = 'ZCI'.
IF komp-pstyv = 'KEN'
l_kobli = 'X'.
ELSEIF komp-pstyv = 'TANN'.
l_kobli = ' '.
ENDIF.
ENDIF. "Sales Doc Check
READ TABLE xt683s WITH KEY kvewe = 'A'
kappl = 'V'
kalsm = 'ZINFAM'
kschl = 'ZPOR'.
IF sy-subrc = 0 .
xt683s-kobli = l_kobli.
MODIFY xt683s INDEX sy-tabix.
UPDATE t683s SET kobli = l_kobli WHERE
kvewe = 'A' AND
kappl = 'V' AND
kalsm = 'ZINFAM' AND
kschl = 'ZPOR'.
ENDIF.
ENDIF. "Pricing Procedure check
CLEAR: l_kobli.
The table which has this mandatory checked is T683S and the field is KOBLI........i've debugged it the routine come up well with item category ZITE1 and the table gets updated with KOBLI = 'X' but when i navigate the screen in VA02 or in VA01 to second item created with item category ZITE2...the table logic does'nt goes and updates the above table............Suggest me with some solution........
Thanks in Advance.....
