How to get the metadata of a SQL VIEW

Hi Colleagues,

Lets say we replicated two tables MARA and MAKT from ABAP to HANA with out changing any Table and their field names.

Lets say MARA consists of following fields :

MATNR, VPSTA,ERSDA,ERNAM,LAEDA,AENAM,VPSTA,PSTAT,LVORM,MTART,MBRSH,MATKL,BISMT,MEINS,BSTME,ZEINR,ZEIAR,ZEIVR,ZEIFO,AESZN,BLATT

Lets Say MAKT consists of following fields:

MATNR,SPRAS,MAKTX,MAKTG

An SQl view MARA_MAKT is built on these two tables MARA, MAKT

Now the following fields are selected as INPUT or OUTPUT attributes of SQL View from both tables.

MATNR,MTART,MBRSH,MATKL,MEINS,SPRAS,MATKG

Now the during the generation of SQL view the INPUT/ OUTPUT Attributes are renamed as below

MATNR- MaterialNumber

MTART- MaterialType

MBRSH- IndusSector

MATKL- MaterialGroup

MEINS-  BaseUOM

SPRAS- LanguageKey

MATKG- MaterialDesc

Lets say the SQl view named as MARA_MAKT is generated successfully.

Now is there any way where we could read the below information any where from

HANA CATALOG or ABAP API's OR SQL PROCEDURES,

1) Based on the SQL VIEW name can we get the information of the correspoding table and the field from which the input attributes formed.

Ex: We give the SQL view Name.

Lets say  MARA_ MAKT.

Question1

Can we get the correspoding ABAP dataelements for all the attributes of MARA_MAKT.

ForExample the below info is req:

INP/OUTATTRofSQLVIEW      ABAPDATAELEMENT

MaterialNumber                       MATNR_DE

MaterialType                           MTART_DE

IndusSector                             MBRSH_DE

MaterialGroup                         MATKL_DE

BaseUOM                                MEINS_DE

LanguageKey                          SPRAS_DE

MaterialDesc                            MATKG_DE

Question2:

Can we get the correspoding tables or table field names of all the attributes of view MARA_MAKT

ForExample the below info is req:

INP/OUTATTRofSQLVIEW      ABAP_TABLE_NAME         ABAP_FIELD_NAME

MaterialNumber                              MARA                                      MATNR

MaterialType                                  MARA                                      MTART

IndusSector                                    MARA                                      MBRSH

MaterialGroup                                MARA                                      MATKL

BaseUOM                                       MARA                                      MEINS

LanguageKey                                 MAKT                                      SPRAS

MaterialDesc                                   MAKT                                      MATKG

Question 3:

Can we get the time stamp information when the MARA_MAKT is created or Changed and what is changed.

Question 4:

Is there any generic approach where we can get the information for all the above 3 Questions for any view SQL view or ATTRIBUTE View or CALCULATION View

Thanks,

Vasavi.
