Parameter ID 'WRK' not working in MM02, why ?

Im using Field Exits because in a client we have to validate that fields have to be filled for a especific werks and material, and the user cant change tab with that field empty.

The thing is that in the code I put

IF INPUT is INITIAL.

GET PARAMETER ID 'MAT' FIELD l_matnr.

GET PARAMETER ID 'WRK' FIELD l_werks.

...

l_matnr is filled but l_werks not, and I dont know why, when I enter MM02 i put a material number and the screen selected ask me werk, vkorg... so I enter the data, besides I can see the werks in the other tabs inside the MM02.

I found a post with exactly the same problem but was not answered.

so, gurus this is a SAP bug or what ?

    Hi,

    Try to export the value to database and import from database

    EXPORT <f1> [FROM <g 1>] <f 2> [FROM <g 2>] ...

    TO DATABASE <dbtab>(<ar>) [CLIENT <cli>] ID <key>.

    The parameter id might be cleard some where.

    Regards,

    Niyaz

    • Hi Niyaz, I dont have the value, that is exactly my problem, Im using a Field Exit in a MM02 screen, and I need the value of werks that I put entering MM02.

      The problem is that the PARAMETER ID is EMPTY when it should be "1000" for example, dont know if this is normal or if it is a bug.

      The funny thing is that Matnr is working, why matnr works and werks dont ?
