Insert records to DDIC table from internal table

Hi Experts,

I have a DDIc table with following table structure. Here I assign seven fields as primary key.

Update Date        - Update runtime system date (PK)

Update Time    - Update runtime system time (at start of run) (PK)

Plant        - WERKS (PK)

Material        - MATNR (PK)

MRP Element type    - MDEZX-DELKZ (PK)

MRP Element    - MDEZEX-EXTRA  (PK)

Date        - MDEZX-DAT00  (PK)

Quantity        - MDEZX-MNG01

Cumulative Quantity    - Calculated cumulative.

Noe my internal table contains 65 records. After inserting records, I checked DDIC table. There is only 7 records added. Because of primary key combination.

How to add all the records to DDIC table?? How to set PK combination to add all the records?

Any possible solution will gratefully accepted.

Regards,

Arindam Samanta.
