EAM_ASSETATTR_GRP_PUB.insert_assetattr_grp Error 'EAM'

Hi Gurus,

Facing a problem in capturing the API error while assigning the attribute group to the asset group by calling EAM_ASSETATTR_GRP_PUB.insert_assetattr_grp. The API is returning the message as 'EAM' with status 'E'. Below is the sample code :

PROCEDURE create_attribute_group (

      p_eam_attr_grp_rec IN xxajc_eam_attr_grp_cnv_valid.rs_eam_attr_grp_rec_type

   )

   IS

      --

      lv_err_msg                xxajc_common_errors.error_message%TYPE :=NULL;

      lv_err_status             VARCHAR2(1);

      lv_source_object_type     VARCHAR2(10)                        := 'API';

      l_association_id          NUMBER;

      lv_return_status          VARCHAR2(1);

      lv_msg                    VARCHAR2(1000);

      lv_record_status          VARCHAR2(1);
