i did it in the screen 1000 , however when i execute it , i got the error : NO INPUT HELP IS AVAILABLE .
what im doing wrong ???

Answer 1

screen 1000 is standard selection screen do try to change it..
If you are refering to standard datalement then you will get the F4 help automatically
example
a)
    tables :  mara.
parameters :
          P_MATNR  TYPE MARA-MATNR .
b)    if you are refering to custom field then you need to add seacrh help at table level or programtically you can use below syntax.
      PARAMTERS :
       P_MATNR  TYPE  ZFIELD MATCHCODE OBJECT H_T134.
Please let me know if you need further info.
