Answer 1

Its mandatory to have loop endloop in both events
PBO and PAI
loop your internal table similarly.
Please check it should be below format
PROCESS BEFORE OUTPUT.
* Set PF Status for screen 100.
  MODULE status_0200.
* This module will initialize the field
  MODULE init_0100.
  LOOP AT t_custmat_asg INTO w_custmat_asg
      WITH CONTROL tc_1
      CURSOR tc_1-current_line.
* It will count the record in internal table
    MODULE set_linecount.
* Screen Modifications
    MODULE status_check.
  ENDLOOP.
PROCESS AFTER INPUT.
* Module AT EXIT-COMMAND
  MODULE exit_0200 AT EXIT-COMMAND.
  LOOP AT t_custmat_asg .
    CHAIN.
      FIELD :
      w_custmat_asg-check,
              w_custmat_asg-kunnr,
              w_custmat_asg-name1,
              w_custmat_asg-asgtyp,
              w_custmat_asg-productcls,
              w_custmat_asg-sctegry,
              w_custmat_asg-ctegry,
              w_custmat_asg-parent,
              w_custmat_asg-frmdate,
              w_custmat_asg-todate,
              w_custmat_asg-frecster,
              w_custmat_asg-salesrep,
              w_custmat_asg-flag,
              w_custmat_asg-username,
              w_custmat_asg-udate.
* Validation For Forecaster.
      MODULE validate_forecaster.
* Validation For Salesrep.
      MODULE valiate_salesrep.
* Validation for Customer
      module validate_customer.
* Validate null value
      module validate_null_vals.
* Validation For Data Changed On The Screen
      MODULE data_changed_0200 ON CHAIN-REQUEST.
    ENDCHAIN.
  ENDLOOP.
