Create Foreign Key with Function module RPY_FOREIGN_KEY_INSERT

[former_member741166]

Hi,

I have to create a foreign key through an ABAP program (not through DDIC functionalities!) on a SAP NetWeaver 2004s system.

I have already found the Function module RPY_FOREIGN_KEY_INSERT but it doesn't work. It runs without any errors but the foreign key is not generated, even when call the Function module DDIF_TABL_ACTIVATE after RPY_FOREIGN_KEY_INSERT to avtivate the table again ( i also tried it with a COMMIT WORK).

Has anyone worked successfully with this Function module and can tell me how it works (e.g. how the parameters of the tables FORKEY_FIELDS and FORKEY_INF have to be set)?

Thank you very much for your help,

Jessica

Hi,

The best approach to this issue is to use the function module "RPY_FOREIGN_KEY_READ". First construct the table the way you want through the DDIC tools and then test this function module and you will get a clear idea of the values you need to pass in the interface.

Hope this helps,

Sudhi

Hi Sudhi,

thanks for your answer! I just created a table with a foreign key through DDIC and read the information with "RPY_FOREIGN_KEY_READ". Then I deleted the foreign key and called the function module "RPY_FOREIGN_KEY_INSERT" with the identical values which have been readout before but the foreign key was not created.

Hi,

I tried it too but unfortunately it is not working for me either. I am not sure why! In principle and theory it should work.

The table gets activated though!

That's true g. But nice to hear that I am not the only one with this problem.
