Data available to User Exit

[former_member445996]

Hi All,

How can I find out if a particular set of data is available in a User Exit? For example, SAP stores Serial Numbers in an internal table, how can I find out if that internal table is available in the user exit.

Regards

You must look at the user exit function module and see the parameters that are provided. These parameter represent the data that will be passed to this function module. Of course, you are not limited to this data, there is a trick using field symbols.

User-exits as well as badi's use predefined interfaces.

Example:

EXIT_SAPLV56S_001

FUNCTION EXIT_SAPLV56S_001.

This means you have these structures and internal tables to play with.

Also you should pay close attention to which of these structures are allowed for changes. You should be able to get more information from the help (in he SMOD or in SE18).

In old user exits (forms in standard code like mv45afzz form save_document_prepare, it is an open concept, meaning you can change a lot of things, but it is not recommended.

Good luck,

Leonardo
