make bol browser fields changeable

Hi,

i want make fields changeable mode, after i retrieve the data from data base by using search query...in transaction code GENIL_BOL_BROWSER.

After i get fields as change mode, i want to modify them...which should be save in database.

i have created custom component set and Z class by copying 'MP' standard component set and its standard class 'CL_CRM_MPIL' and here i have taken super class 'CL_CRM_GENIL_ABSTR_COMPONENT',.

Here I am able to retrieve the data for advanced search and search query objects. by using methods 'GET_OBJECT_PROPS', 'GET_MODEL', 'GET_DYNAMIC_QUERY_RESULT' and 'GET_OBJECTS'.

But here i do not know which method to use for make the fields changeable, which are fetched from data base.

please anybody help me that....how to make the fields as editable and how to save them in database..

Thanks,

Reshma.
