I guess your callback routines in both the function calls to LDB_PORCESS have WRITE statements. Instead, export the data using the EXPORT to MEMORY option. At the end of the secoond function call, use the statement IMPORT from MEMEORY & then manipulate the data to write it out to a list in whatever format you like.

lt_callback-cb_form = i_callback_form.

APPEND lt_callback.
