How to maintain the sequence in the custom table

Question

Hi,
We have custom table where we will store the standard text name based on different flags and it will be fetched the value according to the condition.
Example code
SELECT SINGLE field1
                  field2
             INTO  ( vaiable1 variable2 )
             FROM custom table
            WHERE tdobject = iv_signature
              AND bukrs    = vbdkr-bukrs
              AND vkorg    = iv_vkorg
              AND vkbur    = iv_vkbur
              AND lland    = vbdkr-land1
              AND fkart    = vbdkr-fkart
              AND kschl    = iv_kschl.
  CHECK sy-subrc <> 0.
  SELECT SINGLE field1
                  field2
             INTO  ( vaiable1 variable2 )
             FROM custom table
            WHERE tdobject = iv_signature
              AND vkorg    = iv_vkorg
              AND vkbur    = space
              AND fkart    = vbdkr-fkart
              AND kschl    = iv_kschl.
  CHECK sy-subrc <> 0.
SELECT SINGLE field1
                  field2
             INTO  ( vaiable1 variable2 )
             FROM custom table           
            WHERE tdobject = iv_signature
              AND vkorg    = iv_vkorg
              AND vkbur    = space
              AND fkart    = vbdkr-fkart
              AND kschl    = space.
The solution I created to avoid the select is, i have created the FM with all parameter. Addition to the FM, I have created a Table as well to maintain the flag.
New table                                                                               
TDOBJECT   TDID BUKRS VKORG VKBUR KUNNR      MWSKZ AUART VGBEL_AUART KTGRM LLAND FKART WERKS KSCHL STNAME                                                                               
FOOTER                                                                           X     X           ZNET_DICI_FTR_FI  
FOOTER                                                                           X     X           ZNET_DICI_FTR_NL  
FOOTER                X     X                                                    X                                   
i.e. say example if we maintain the value in the custom table based on the first select query. Then we need to maintain the flag in the table which was created newly.
Note In the both field the key fields are same.
The problem now is we have plenty of select query for different condition, i though of maintain the sequences of the entries. But my worry is how many sequence number will be maintained and in what bases it will be maintained.
Could you please help me to resolve this problem?

Hi,
I got your requirement as,
whenever a new entry is made in the table, one sequence has to be maintained somethign like serial number and everytime it has to be incremented. If it is so, then you can go for an additional field as serial number. Then get the max serial number from the following select query:
select max(serial) from cust_table
into v_serial.
Now, when you make a new entry, just give (v_serial + 1) to serial number...
Please let me know if i understood wrongly... or what you want...
