Key assignment in MDG

[Pawan_Mahto]

Hi,

I had selected Key Assignment for an Entity as "Key Can be Changed; Internal Key Assignment possible"  as an option initially and now the requirement changed so i need to change Key Assignment to "Key Can not be changed; No internal Key Assignment".

During change I am getting an error stating: "Data model XX is already active and entity type XXXXX is contained in the active version. In this case, you may no longer change the type of key assignment for entity type XXXXX."

Does any one came across same error or do you know How can change this to meet my requirement?

Thanks,

Dear Pawan ,

It could be standard MDG Limitation . I guess you are using FLEX mode for this entity .

If you are in FLEX mode the May be you could delete all the data in your generated tables and try it .

Because of already existing data the framework is giving this error .

Thank you .

Correct, with an activated data model, this is not possible.

http://go.sap.com/docs/download/2015/07/ba10f64d-5b7c-0010-82c7-eda71af511fa.pdf mentions report USMD_DELETE_DATA_MODEL

This report deletes the active data model including all active data (for flex entities) and inactive data. This data will be lost (change request as well as active data for flex entities).

Afterwards, I assume changes to the key assignment will be possible again.

Best regards, Ingo Bruß

I am using reuse mode not the flex..will it work in that case as well?

That's independent of Flex vs. Reuse
