JDBC: Complete IDOC too large for Oracle DB

Question

Dear all,
I received IDOCs from SAP system that should be stored into a Oracel DB.
The IDOC should be saved as complete XML structure in a single DB field.
I have two problems:
1) The IDOC contain all fields. If a field is empty, it will be transmit like <ERSDA>/</ERSDA>
     This makes the IDOC very large. This is because of a filtering process in bd53 that
     have  to be keeped.
2) We should save the complete IDOC in on DB field. So I took an xsl mapping to copy the
    complete source into on target field. The DB could only store 4000 characters in one field, but
    our IDOC got more characters.
So I have to downsize the source IDOC (favorite) or have to split the target. But this would make it
very complexe I think.
Can someone give me a hint for filtering the not necessarily fields in PI??
As an alternative we could store every single segment of the IDOC in a single row of the DB.
That would be easy if we would read the IDOC data directly from SAP table, but as IDOC XML it
is almost not technically feasible, is it?
Any hints?
Thanks
Chris

Thanks for replies.
@all:
Is there an option to get an IDOC like it is saved in SAP system in
table EDID4?? There is an IDOC split in segments.
@Baskar
The target field is already CLOB data type. But the admin told me, that the maximum
numbers of characters is reached by 4000 chars.

It got this / for fields that should not be change. But our target system does not need this infos. But
the SAP system will not change this.

Where do I use this option? In IDOC sender channel I could not find it.
>IDoc(segment)-->anystring function-->DB Field(Target).
What does this mean? Will you filter the segements of an IDOC?
If I could split a complete IDOC into single segments it would help.
Can you please tell in detail what you mean?
Thanks
Chris
