Hi ...

I need to perform a validation check before a record inserted / updated into my own table.

It was done through a maintenance view.

What I am doing is to code a function ( under Screens - access through SE80 )

process after input.

... codes

--> i put my function here.

... codes

module set_update_flag on chain-request.

I am just wondering what happen over here.

In the function I developed, will SAP call this function 1 record at a time OR all the records that changed in the table in batch ?

Thanks.

hello D ,

yeah , SAP will execute ur functions.

one thing u need to remember while adding add.functionality in TMG screen , when u re-generate these screen , ur codes will be goes off..

sample codes looks like

 
Process after input. 

  loop at extract. 
    module liste_init_workarea. 
    chain. 
      field ytable-versnc *module versn.*--> ths is my validatin module for field versnc 
      module set_update_flag on chain-request. 
    endchain.
