Hi experts,

2001    0200	02    30    *    *******CHANGING IT9201 ACCORDING TO IT2001,0200
2001    0200	02    31    I    MOD,9201,0200,,(P2001-BEGDA),(P2001-ENDDA)/D
2001    0200	02    32    W    P9201-BEGDA=P2001-BEGDA
2001    0200	02    33    W    P9201-ENDDA=P2001-ENDDA

But if  I change P2001-BEGDA  and P2001-ENDDA system don't react to these changes and P9201-BEGDA and P9201-ENDDA still the same. what is wrong on my dynamic action ?

Thanks in advance,
