Binding table parameter from method to multi-line container e lement in task

Tue Jul 6 11:42:03 EDT 2004

Hi,

I think I figured out what caused my problem (or better, how to solve it):

The basis of my workflow is a standard SAP workflow for handling price blocks in invoices (WS20000397, Treatment of inv.
blkd for price, Log.IV). We made some changes to this workflow.

In the workflow a (standard SAP) multi-line container element is used: 'NonClearableItems'. It is defined as data type
reference table RSEG_BUZEI (thus no field is specified, which means a reference to a whole table or structure). When
using a container operation to assign an empty value to this container element the following error is displayed:
"Operation '=' between data type 'u' and 'u' not allowed".

I changed the data type definition: table RSEG_BUZEI and field BUZEI. Now it's possible to use the container operation to
set an empty value for the container element. Also I changed the parameter of the methods and the container of the
standard tasks involved (this works for me because the structure RSEG_BUZEI only consists of one column). All works fine
now. Still I do not know how I should have solved my problem in case the structure consisted of more than one column
(then specifying the field BUZEI would not be sufficient).

Regards,

Fred
