multiline attribute problem

[Dart, Jocelyn]

Koenraad,
Why not use the WAPIs - i.e. SAP_WAPI_READ_CONTAINER and SAP_WAPI_WRITE_CONTAINER in your method?
Regards,
Jocelyn Dart

Subject: multiline attribute problem
 
 
Hello all
 
We have a problem with a multiline attribuut.  The situation is as
follows:
 
1.  multiline (table) attribute in wf container filled with elements
2. binding with task and method container works normal
3. in the method the multiline (table) attribute is cleared and refreshed,
so all table elements are deleted
4. binding between method and tasks works...  table in task container is
cleared (set by SWC_SET_TABLE macro)
5. binding back to the wf container of this empty multiline (table)
attribute does not work...   Elements in wf container are not cleared.
 
After talking to OSS support it seems that this is SAP standard.  A empty
attribute is seen as "no data" and is not copied back to the wf container.
A possible solution is Note 387516 which modifies SAP standard.
 
We are wondering if there isn't a macro like function to directly modify
(clear the attribute) the wf container, so we are not obliged to modify
SAP standard.
 
Kind Regards and hoping for a solution....
