Export of applicationfiles - filename

Hello,

We want to export applicationfiles from DMS. This can be done easily with CV04N, and then use Distribution function. Applicationfiles are then written to the folder that is configured.

Problem is, the filenames generated by the system are meaningless (running number). The recipient of the files needs to know the relation between applicationfile and metadata (DIR data).

We would like to have the filename to be built up like this:

DOKNR_DOKAR_DOKTL_DOKVR_DAPPL_ddmmyyyy_nnnn (where nnnn is running number). We are aware there is no standard functionality for this.

How to achieve this (FM, BAPI etc)?

Will reward points.
