REG: Filtering the value from IDOC segments

Hi All,

Requirement: I have same segments repeating multiple times in IDOC and based on the field value of ATNAM i.e. " Glassglo " it has to filter and populate the ATWRT filed value in the taget element else it has to pass constant value.

Example :  Source Segment  :  YY_Class     -    ATNAM        value    pollo

                                                                            ATWRT                       5467

                                                  YY_Class -       ATNAM        value    Apllo

                                                                            ATWRT                      256

                                                   YY_Class -       ATNAM        value    Glassglo

                                                                            ATWRT                      65974

It has to filter the segment and pass the value 65974 to the target element OLD_GLO else constant value. Please help me in providing the solution.

Thanks & Regards,

Ravi.
