Hi,
We can achieve the IT105 and SU01 update in the Dynamic actions itself.
In V_T588M -
You can write a dynamic action as follows -
P P0000-STAT2='0'
I MOD,0105,0001,,(P0000-BEGDA),(P0000-BEGDA)/D
F ZUSRCHG
Where the function ZUSRCHG would be the custom sub-routine which will call the BAPI BAPI_USER_CHANGE to change the Valid to date.
