Hi Raj
In case of stadnard monitor, I think there is no possibility to store date in to other table.
In case of custom monitor, technically it may possible, you need to think of better data
management design and update mechanism.
If the requirement is not storing data, rather you wan to re-use stored data, I recommend to
analyze some way to retrive data from stored data. (/SSF/PTAB, /SSF/BTAB<as of ST-A/PI R).
For example, if your requirement is, including IDoc number in noitification mai, then you can
refer to SAP Note 1609090.
Here by using notification Badi, the sample codes<Function Module> retrives stored IDoc data.
So like this way, there is possibility to retrive stored information.
Best Regards
