Filter in SLT for last 3 months data

Hello all,

There is a requirement to get only last 3 months data in SAP HANA for table FAGLFLEXA.

This needs to be done based on posting date field. So, it seems the below will need to be done –

1. 1.       If 1^st of every month drop data otherwise do not drop complete data from table FAGLFLEXA in sap hana. (This is for taking in account the performance when loading data in SAP HANA so dropping data everyday is not recommended)

1. 2.       Calculate 1^st day of the previous 3^rd month (example if 15^th April 2013, then calculate 1^st Jan 2013).

1. 3.       Now take records where data is from 1^st Jan 2013 to 15^th April 2013 in above example.

This will need to be done under tab IUCC_***_RUL_MAP in transaction IUUC_REPL_CONTENT.

Can you please help me to write the code for this?

If there are any other suggestions, please let me know.

Thanks.
