BADI for CRM CASE save

Hello Folks,

I am new to SAP CRM Case Management and I am looking for any BADI which would be triggered when a CASE (SAP CRM CASE which is not one order) is Saved.

I have certain requirement which I would like to implement in a BADI rather than the EH_ONSAVE event of the CASE.

Please suggest any BADI through which I would be able to change the Header data and also its RELATED object data.

I did find BADI CRM_ICM_REL_C, but it is triggered multiple times and not only on save.

Another BADI SCMG_CHNG_BFR_STR_C gets triggered on CASE save but I don't get any data in the interface method and hence not able to use either.

Any help is much appreciated.

Thanks,
ND
