Is it possible in BAPI to ignore a reqd field in table while uploading data

Question

Dear SAP Guru's,
A GL account had "allow posting without tax code" unchecked, which meant that tax code had to be specified in order to post balances/data in that GL account.
But during cutover, while uploading balances using BAPI, the conversion team was able to load the balances into the GL account without specifing tax codes to such GL accounts.
Is there such a posibility in BAPI to change the code to ignore a required field during data load??If so what is it?

Answer 1

No, sorry, I mean I copied the data vector (model.getDataVector()) to an other vector, not the model. And the problem is that the serialized data did not reflect the changes if I just change vecor values, so this is why I reinstantiated the full model. I think this is rather a java io issue, not a swing issue, it seems any object I serialize will not be refreshed if I just change some attributes in it and not the full variable. Can this be true?
On the othe hand
table.setAutoCreateColumnsFromModel( false );
quite simplified my framework, which is great!
The old framework looked like this:
public BaseTblModel resetModel() {                    
removeListeners(tm);
removeListeners(tb);          
tm = new TrackTblModel();     
tb.setModel(tm)
reinstallEditors(tb)
addListeners(tm);
addListeners(tb);     
return tm;
Now with table.setAutoCreateColumnsFromModel( false ); it looks like as simple as:
public BaseTblModel resetModel() {                    
tm = new TrackTblModel();     
tb.setModel(tm)
return tm;
So it would be better If I could leave out this step as well, because I do it just because of the mentioned serialization problems.
