Dynamic Actions - Delete other infotype record

Hi,

I add a Delete infotype record at Dynamic Actions as below:

Infty Action No Maintain Func Name

0008 08 305 I DEL,0007,,,(P0008-BEGDA),(P0008-ENDDA)/D

However, it did not follow the P0008-Begda and P0008-Endda. For example, if IT0007 has two records but IT0008 has three records and user is delete the third record of IT0008 where the IT0007 does not has the same begda and ennda. However, the dynamic action still will delete one of the IT0007 record that is not same date with IT0008. Is it because the DEL,0007,,,(P0008-BEGDA),(P0008-ENDDA)/D

is not correct? Please suggest how to make it work. Thanks.
