Problem in Logical Databse Call via Function Module - Urgent

[aaruljothi]

Hi Experts,

To use the Logical Database(LDB) in the function module(Custom) I am using the function module - LDB_PROCESS. But I didn't get any output. I am attaching the code. Please Help me in this.

DATA : W_LDBNAME LIKE TRDIR-LDBNAME.

DATA : IT_CALLBACK LIKE TABLE OF LDBCB WITH HEADER LINE,

IT_SELECTIONS LIKE TABLE OF RSPARAMS WITH HEADER LINE,

IT_PERNR TYPE TABLE OF PERNR WITH HEADER LINE.

MOVE 'PNP' TO W_LDBNAME.

IT_CALLBACK-LDBNODE = 'PERNR'.

IT_CALLBACK-GET = 'X'.

IT_CALLBACK-CB_PROG = SY-CPROG.

IT_CALLBACK-CB_FORM = 'CALLBACK_PERNR'.

APPEND IT_CALLBACK.

CLEAR IT_CALLBACK.

IT_SELECTIONS-KIND = 'S'.

IT_SELECTIONS-SELNAME = 'PNPPERNR'.

IT_SELECTIONS-SIGN = 'I'.

IT_SELECTIONS-OPTION = 'EQ'.

IT_SELECTIONS-LOW = '100178'.

APPEND IT_SELECTIONS.

CLEAR IT_SELECTIONS.

CALL FUNCTION 'LDB_PROCESS'

hi,

i guess the statement "* SELECTIONS = IT_SELECTIONS"

is commented in the code ....uncomment that statement and i think u may get the output

Thanks,

Hi Jyothi,

I think adithya is right b'coz we have to pass the values for the selection screen after executing that with out that we may not get the data.so check it out whether it works or not .

Hi,

I think Arul commented the 'it_selections' while trying out.. I couldn't get the fm work for PNP.. it worked fine with the FI LDBs.. just didn't seem to like the PNP..
