Set 1 row in an assignment block to read-only

[nisha_vinod]

Hello Experts,

I have the following requirement for an Assignment Block :

-------------------------------------
A       AA
B       BB
C      CC
D      DD
E      EE
-----------------------------------
T1    T2
-----------------------------------

Here the last rows indicate sum of the column values and it need to be read-only field but it should be sets with the column sum.

Any suggestions as to how to achieve this requirement?

Hi Nisha,

Depending on whether tablview is model/value node and when should the sum be calculated - you can write in do_init_context or do_prepare_output or on event handler of some button (if it's on button click).

Looping on the collection wrapper - create one more entity when you reach last row of collection - keep adding sum to a variable, create new entity in last, set attribute of the entity column with the sum and add it to collection.

Also, to make only last row editable - you can either implement iterator and write code to enable/disable in IF_HTMLB_TABLEVIEW_ITERATOR~GET_COLUMN_DEFINITIONS method of iterator class or write code in GET_I method to make the field disabled if the column name of tableview is 'SUM' or whatever name has been fixed for it.

Thanks,

try to set a debug point in get_i method of the attribute.

The sum should be calculated when you do an action. On action you can set a value of a global parameter and read that parameter in get_i method and return the value as false.
