Hi,
         In many master data infotypes the data is stored in the form of repetitive structures. For example infotype 0008, the structure wage type line is available for 20 times, that is an employee is eligible for having 20 different wage types based on his benefits. When evaluating repeat structures, you must ensure that all fields are entered. In the case of the Basic Pay infotype, 20 * 5 = 100 fields are queried.
To use this method of evaluation, define a field string whose structure corresponds to the fields in one line of the repetitive structure.
Example for understanding the repetitive Structure
     Say, for an employee you want to know that for what all wage types an employee is eligible for the latest period you mentioned on the selection screen.
  Using LDB (PNP)
Program:
  Report zhr_repstru.
  Tables Pernr.
   Infotypes 0008. 
u2022     You have to declare a structure same as repetitive structure in the 0008 infotype
   Data: begin of s_wagetypes,
                Wagetype type p0008-lga01,
                Amount      type p0008-bet01,
                Hours         type p0008-anz01,
                Unit            type p0008-ein01,
                Ind             type p0008-opk01,
            End of s_wagetypes, 
u2022     Selecting data from the Data base       Get pernr
u2022     Getting the latest record based on the selection period.
      RP_PROVIDE_FROM_LAST P0008 SPACE PN-BEGDA PN-ENDDA.
u2022     Now knowing for what all wage types the employee is eligible.
Do 20 times varying s_wagetypes from p0008-lga01 next p0008-lga02.  If s_wagetypes-wagetype is initial.
o     Here the data is stored sequentially, i.e., if the employee is eligible for 5 wage types then all the 5 wage types are stored sequentially in lga01 to lga05 respectively. So, if say the lga05 is initial then it is understood that, employee is eligible for only 4 wage types and from lga05 to lga20 structures will be empty so, we need not process further
            Exit.
        Else.
           Write: / s_wagetypes-wagetype,
                        S_wagetypes-amount.
        Endif.
Enddo.
