datasource - postload function on temporary tables.

Hello,

On postload function (table component function) can I do:

this.write(); (On temporary table).

What I get is:

Record with RecId 1616 in table 'MyTable' has mismatching Sequence field values. Original value was 84, new value is 7.

Cannot edit a record in <MyTable> (<MyTable>).
The record number does not comply with the original number. If the table uses entire table cache, this may be caused by the cache being flushed. Restart your job if this is the case.

Why? and what I can do instead?

Thanks :)
