Hi Mahesh,
I do not believe this is possible on SAP standard screens using just the extensibility explorer and change transactions.
Usually when using the UI designer for a custom UI this would be difficult (but not impossible) to.
For a custom screen, when I bind the read-only state of a list column to a boolean flag in line level, the behaviour would be as follows:
The entire column is read-only or read-enabled, depending on the state of the flag of the *selected line*. The *selected line* part is the important bit.
Thus if you select a line where the flag is true, the entire column (i.e. all line items) should change to read-only.
If you select a line where the flag is false, the entire column should change to read-enabled.
I do know a work around for this behaviour for custom screens but not for SAP standard screens.
Best regards,
Ludger
