hi experts,
i used bapi to update the changes made in data of table control in modulepool.
like i <b>changed serial number and short text of equipment</b> . <b>now when
i simultaneously go for transaction ie02 i,e equipment change in another session with table control open in other session , and now i changed data of particular equipment number in ie02 , now when i use refresh button in table control that change should be affected. how would be the logic for the refresh button</b>
<b>when i use the refresh button in the table control , screen should be refreshed or filled with updated data. so what is the flow and logic for that.</b>

just refresh the internal table associated to the table control. So in PBO when it is trying to load the records from internal table to the table control, it will not have any records so it will be blank.
The basic concept behind table control is In the PBO it will load the records from internal table and in the PAI it will load back the updated records into internal table. So, if you make internal table empty it will not have records in the PBO to load the table control and it will be blank.
