BDC issue - passing space

Hi,

I am recording (using T.Code: SHDB) a transaction, where there is a Table control. when i select the record, the indicator is 'X' and then i proceed with function buttons. After finishing the work with that record, i have to deselect the record, i.e. i have pass space ('') for the indicator.

But the passing of space is not valid with BDC recording. i.e. the BDCdata will not get appended with the field name and value.

Can anyone suggest solution for this or an alternative.

regards

satya
