Dynamic Column name change based in filter selection

HI TEAM,

We have a requirement the coloumn names need to change based on filter used.

Example :

We will be using Client as filter hence when the client is changes the coloumn names need to change according to the client requirement.

Please note that the data type remains the same for all the clients we will only need to have the column names changed according to the client ( We have closed to 200 clients that uses the same report however different column names according to their requirement ) All assistance is appriciated I dont want to create 200 different reports it becomes an overhead for changes in future.

Thanks,

Sudhir.M
