Hi,

The field statement for the individual screen field T_HEADER-DOCNO checks for the changes and executes the module 0200_GET_DOCNO_DETAILS .

The chain .. endchain statement checks for change in any one of the screen fields grouped together with the embedded field statement. If any one field's value is changed, the relevant module is executed.

And when a warning / error statement is triggered within this module, it has the effect on all the fields inside the " chain .. field: .. " statement.

This question should have been posting in UI programming.

Also, check out the help documentation for the key words: CHAIN and FIELD.

With Regards,
