Selection screen for custom table

Question

We have developed a custom table and user want to have a selection selection screen similar to SE16. There are 9 fields in the table and user can enter data to the selection screen with any combination. My question is how do I filter based on the user input ? DO I need to write multiple SQL for different combination of selection screen parameter within IF ELSEIF statement ? If so then there will be huge number of SQL within IF & ELSEIF statment for 9 selection parameter. Please suggest if you have any better ideas.

Answer 1

Even after using select-option along with IN statement in where clause , it did not work.
I used following selection screen defination :
SELECTION-SCREEN: BEGIN OF BLOCK B2 WITH FRAME TITLE TEXT-002.
SELECT-OPTIONS: P_PCBUS FOR MARA-ZZPC_BUSINESS NO-EXTENSION NO INTERVALS,
                P_PCBUS1 FOR MARA-ZZPC_BUS_SUB1 NO-EXTENSION NO INTERVALS,
                P_PLNFMT FOR MARA-ZZPLNG_FORMAT NO-EXTENSION NO INTERVALS,
                P_PRDB FOR MARA-ZZPROD_BRAND NO-EXTENSION NO INTERVALS,
                P_SEASCD FOR MARA-ZZSEASON_CODE NO-EXTENSION NO INTERVALS,
                P_SNP FOR MARA-ZZSUP_NET_PATH NO-EXTENSION NO INTERVALS,
                P_MAT_DC FOR MARA-MATNR NO-EXTENSION NO INTERVALS,
                P_MAT_MG FOR MARA-MATNR NO-EXTENSION NO INTERVALS.
SELECTION-SCREEN: END OF BLOCK B2.
and SQL statement :
SELECT ZZPC_BUSINESS
      FROM ZTB_RTL_TO_WHS
      INTO TABLE TA_ZZPCBUS
      WHERE ZZPC_BUSINESS =  P_PCBUS
      AND  ZZPC_BUS_SUB1  IN  P_PCBUS1
      AND   ZZPROD_BRAND   IN  P_PRDB
      AND  ZZPLNG_FORMAT   IN  P_PLNFMT
      AND  ZZSEASON_CODE   IN  P_SEASCD
      AND  ZZSUP_NET_PATH  IN  P_SNP
      AND  ZZD_MATNR       IN  P_MAT_DC
      AND  ZZM_MATNR       IN  P_MAT_MG.
While executing program, I only enterd value for the field P_PCBUS. Though record present for that value, I rcvd SY-SUBRC = 4.
ANy Idea?
